• Social license to operate highlights need to reassess industry practices.

• Certain tack and riding styles risk injury, stress, fear, biomechanical dysfunction.

• Riders may influence horses via their emotions, fitness, skill level and education.

• Unidentified lameness and health concerns threaten ridden horse welfare.

• To promote welfare, precautionary principle should be applied when lacking evidence.

Equestrian sport’s social license to operate has come under scrutiny due to concerns surrounding the well-being of ridden horses. Inappropriate equipment use, such as harsh bits or overtight nosebands, can negatively influence well-being by generating inescapable pressure or pain on the sensitive structures of the horse’s head and limiting natural behaviours. Restrictive equipment may also be used to generate exaggerated, stressful and uncomfortable head and neck positions such as hyperflexion. Saddles must be properly fitted to both horse and rider to ensure appropriate distribution of kinematic forces across the horse’s back and promote the horse’s comfort.

The rider’s balance, body control, ability to cue the horse, decision-making capabilities and understanding of equine behaviour can also influence the horse’s experience under saddle. Physical health conditions such as ulcers or unidentified lameness can cause pain, stress and mechanical damage if left untreated, which may be further exacerbated by riding. The ridden horse’s well-being is a multifactorial and complex equation.

However, riders must seek to understand these nuanced aspects of well-being, and act on the precautionary principle (stating that a practice should not be assumed harmless until it is proven to be so) if there is not yet enough evidence on a subject to draw firm conclusions. Such directives will safeguard the welfare of ridden horses and the social license to operate for equestrian sports.

When Position Becomes Pressure: Behind-the-Vertical Effects on Behaviour

Horse sports are often under public scrutiny, especially when it comes to horse welfare. This study looked at how the position of a horse’s head and neck while being ridden affects their behaviour, particularly signs of discomfort or resistance. 🐴

Researchers observed elite dressage horses during competition warm-ups and tests, as well as horses shown in educational videos. In total, they analysed 191 rides via video footage frame by frame and recording how far the horse’s nose was in front of or behind the vertical, the angle at the poll, and behaviours such as unusual mouth movements and tail swishing. 🎥📊

They found that when a horse’s head and neck were held more “behind the vertical,” the horses showed more conflict behaviours, which can indicate discomfort or stress. A key point was identified at around 7.5 degrees behind the vertical, where these behaviours became more likely to increase. Stallions showed more of these behaviours than mares and geldings, while factors like age, breed, and bit type did not make a clear difference. 📉

Overall, the study suggests that paying close attention to head and neck position during riding can play an important role in supporting the horse’s comfort and welfare, especially in competitive dressage.

This study was limited by the range of head and neck positions observed, as most horses were ridden with their nose behind the vertical, which means the suggested cut-off value may not accurately represent the full range of riding positions. In addition, the warm-up phases were not standardised and video angles varied, which may have affected how consistently head and neck positions could be measured across all rides.

When “Bad Behaviour” Is Pain: Rethinking Behaviour in Sport Horses

This review examines “undesirable” and aversive behaviour in sport horses as a potential manifestation of underlying pain, with a particular focus on equine gastric ulcer syndrome (EGUS). 🐴🩺

The authors discuss how behavioural changes may reflect pain, fear, or learned anticipatory responses rather than “bad behaviour,” and highlight the challenges of interpreting behaviour given the influence of training, rider skill, breed, personality, and arousal. Current behavioural and pain assessment tools, including the Ridden Horse Pain Ethogram, are reviewed, with caution advised regarding their application outside the populations in which they have been validated. 📊

The evidence linking EGUS to aversive behaviour is mixed. While some studies and clinical reports associate conditions such as girthiness, changes in ridden behaviour, and eating patterns with gastric disease, other work finds weak or inconsistent relationships, particularly for glandular disease.

Recent findings using the Ridden Horse Pain Ethogram provide preliminary support for an association between gastric lesions and aversive ridden behaviour. The review emphasises that musculoskeletal disease, EGUS, and dental disease are the three most important differential diagnoses when evaluating pain-based behavioural complaints. 🦷📉

The authors advocate a multisystem, bias-aware diagnostic approach that integrates lameness evaluation, gastroscopy, and dental examination, rather than focusing on a single body system. They stress the importance of distinguishing between ongoing pain and learned behavioural responses, particularly in chronic conditions, and highlight the role of behavioural modification alongside medical treatment.

The review concludes by calling for improved definitions of clinical “healing,” greater use of objective outcome measures, and further research into tools, including wearable technologies, to better link behaviour, pain, and welfare in horses. 🔬📡

Why Do Owners Train the Way They Do?

The way horses are trained has implications for equine welfare and training success, yet little is known about the factors that influence horse-owners’ choice of training approach. Limited understanding in this area will hinder the development and dissemination of evidence-based training advice to owners. Consequently, this study aims to identify demographic and attitudinal factors that influence horse-owner training approach selection. 🐴

A 22-question online survey collected information from 1,593 horse-owners about their demographics, equestrian activities, goals and beliefs. Participants rated how likely they were to use six different horse training approaches on a five-point scale. 📊

Several factors were associated with reported training approach use, including age, gender identity, goals, activities, industry role and whether they had training in animal behavior. Beliefs about equine sentience, cognitive ability and whether science should inform horse training correlated with likelihood of applying aversives. 🧠

This study provides insight for further research and development of educational strategies to reduce the use of training approaches that may compromise equine welfare.

This questionnaire-based study is limited by self-selection and response bias, so the findings may not represent the wider horse-owning population. The results reflect reported intentions rather than actual training practices and lack information on how methods are applied or on horse-related factors that may influence training choices.

Are We Looking in the Right Place?

• Humans follow a horse-specific visual search pattern: eyes, ears, then nose/mouth. 🐴
• Eyes play a significant role in assessing equine emotional states. 👀
• Moderate pain was assessed with similar accuracy across participant groups.
• Non-equestrians faced challenges with recognizing the absence of pain.

In daily interaction with horses, humans primarily rely on facial expression as a non-verbal equine cue for emotional information. Difficulties in correctly recognizing these signals might arise due to the species-specificity of facial cues, possibly leading to diminished equine welfare and health. This study aimed to explore human visual search patterns when assessing equine facial expressions indicative of various pain levels, utilizing eye-tracking technology.

108 individuals, classified into three groups (affinity with horses (N = 60), pet owners with no affinity with horses (N = 32), and individuals with no affinity with animals (N = 16)) participated in the study; with their eye movements recorded using eye tracking glasses they evaluated four photos of horses with different levels of pain. 📊

Participants’ accuracy was measured by comparing their ratings to a “gold standard” reference score. They also looked at how they viewed the images, including how many times and for how long they looked at specific areas (eyes, ears, nostrils, and mouth) across the four photos.

Highlighting the critical role of the eyes as key indicators of pain, findings showed that the eyes played a significant role in assessing equine emotional states, as all groups focused on them for a longer time and more frequently compared to other facial features. Also, participants showed a consistent pattern in how they looked at a horse's face, first focusing on the eyes, then the ears, and finally the nose/mouth region, indicating a horse-specific pattern.

Moderate pain was assessed with similar accuracy across all groups, indicating that these signals are broadly recognizable. Nevertheless, non-equestrians faced challenges with recognizing the absence of pain, possibly highlighting the role of experience in interpreting subtle equine expressions.

Future work could further investigate why humans follow this visual search pattern and whether they recognize the significance of a horse's ears. Additionally, emphasis should be placed on developing targeted training interventions to improve equine pain recognition, possibly benefiting equine welfare and health. 🔬

Differences in lighting, background noise, and viewing conditions could have influenced focus, and some participants compared posters with each other, which may have biased their scores. The study also used only one photo to represent each pain level, meaning results may partly reflect the unique features of those specific images rather than pain level alone. Future studies should include multiple photos per pain category to improve reliability and generalisability.

Stabled but Not Social: The Welfare Cost of Isolation

• Social contacts reduce stereotypies in horses housed individually. 🐴
• Horses with social contacts show fewer negative behaviours with humans.
• Horses with social contacts are less vigilant when groomed by humans.
• Emotional state can be positively influenced by social contacts. 💚
• Social contacts, even temporary, improve the welfare of horses.

The housing conditions of domestic animals influence their welfare; their emotional state can be negatively affected if their needs are not met. This can lead to behavioural changes or disorders that can damage the animal–human relationship. In social species such as horses, Equus caballus, social contact is a fundamental need that is severely restricted by individual housing. Thus, this study aimed to evaluate the impact of socialization on the emotional state of horses in different contexts.

They studied 20 adult horses housed in individual stalls. The horses were divided equally into two experimental conditions: horses without social interaction (isolated condition) and horses with the opportunity to interact temporarily with a conspecific (social condition). For 4 months, the horses under the social condition interacted in pairs for 1 h daily in a meeting box.

Throughout this period, the behaviour of the entire sample of horses in individual stalls and during grooming sessions with humans was recorded. In addition, a judgement bias test was conducted at the end of the study period. In the individual stall, we collected indicators of poor welfare such as hypervigilance, apathy, aggressiveness towards humans and stereotypies. During grooming, we observed negative and positive behaviours, alertness levels and general attitude.

Horses in the social condition exhibited fewer stereotyped behaviours in the individual stall than the isolated ones. During grooming, they expressed fewer negative behaviours, spent less time in a vigilant state and showed a less tense attitude. In the judgement bias test, horses in the social condition showed an optimistic bias compared with the isolated horses.

These findings indicate that horses that are allowed to interact socially perceive their environment more positively than their isolated counterparts. Temporary but regular social contacts positively affect the emotional state of horses in various contexts, indicating an overall improved welfare. 📊

This study is limited by its small sample size and the fact that horses were assigned to conditions based on owner preference rather than randomisation. Additionally, the work was conducted in a specific management and seasonal context (sport horses housed in individual stalls during winter), so results may not directly translate to other housing systems or times of year.

Strap Tighter, Move Shorter: Noseband Pressure and Stride Reduction

Noseband tightness has received increasing attention within equitation science, but there is still limited research examining how it affects horse behaviour or performance. This study aimed to measure peak pressure under the noseband in live horses at three different levels of tightness and to assess how noseband tightness influences limb and back movement. 🐴📊

Eight horses were tested, with noseband tightness set using the International Society for Equitation Science (ISES) taper gauge at three standardised settings: two fingers, one finger, and zero fingers. Peak pressure under the noseband was measured using pressure sensors, and motion capture technology was used to analyse limb and back kinematics. 🎥📏

Peak pressure increased as the noseband was tightened, with pressures at the one-finger and zero-finger settings showing increases of 54% and 338%, respectively, compared to the two-finger setting. As noseband tightness increased, stride length decreased, showing a significant negative relationship. On average, stride length decreased by 6.2% at the one-finger setting and by 11.1% at the zero-finger setting when compared to the two-finger setting. 📉

In conclusion, tightening the noseband increased peak pressure and had a negative effect on horses’ movement, particularly stride length.

The study had several limitations, including analysing movement only from the side, which captured forward–backward limb motion but not side-to-side or rotational movement, as well as unavoidable measurement error from skin movement and differences between horses in training level.

How Strong Is the Human–Horse Bond? And Can We Measure It?

Research on human-animal interactions has established that numerous benefits can result from human relationships with diverse companion animal species in the domains of physical, social and psychological outcomes. 🧠🐾

Therefore, numerous animal-attachment scales have been developed to measure the extent of individual human’s attachment to their companion animals. Validated attachment scales exist for humans with dogs and cats. However, to date there has been limited research into the attachment that forms between an owner or keeper and their horse, and few attempts to create an instrument that is capable of capturing its different domains. 🐴

This study describes the development of the Human-Equine Attachment Scale (HEAS) and investigates its reliability and validity in the context of owner attachment to horses used for casual and competitive riding. The scale was tested with over 3,600 horse owners in the UK.

They completed a 25-question survey where they rated how strongly they agreed with different statements about their relationship with their horse. The questions were based on well-known measures of how people bond with animals, adapted specifically for horse ownership, with a few extra questions added to reflect the unique aspects of owning and caring for a horse. 📊

The researchers tested how well the questionnaire worked and removed a few questions that overlapped too much with others. The final version measured six main parts of the human–horse bond and showed good overall reliability, meaning the scale gives consistent and trustworthy results. ✔️

The subscales indicated 1) companionship, 2) personal wellbeing, 3) dependence, 4) status, 5) growth and 6) sacrifice were key factors within the scale. The study establishes HEAS as a coherent and psychometrically robust measure of human-equine attachment, with potential for utilisation in social science and health related research, and to support research to improve successful pairings between horses and humans. 🤝

The sample may be biased because participants were recruited through a science-focused equine website, which may not reflect the wider horse-owning population. The questionnaire was also only completed once, so future studies should check whether people give similar answers over time.

Tightening the Girth: What Happens Beneath the Saddle?

Horse tack, including the girth (the strap that holds the saddle in place), can influence how comfortable and free-moving a horse feels when being ridden. 🐴

This study investigated how different girth designs and levels of girth tightness (tension) affect pressure beneath the saddle and forelimb movement during a rising trot. Six regularly ridden horses were tested using two girth types: a straight design and an anatomical (shaped) design, at two levels of tightness. 🐎

Changes in girth type or tightness had minimal effects on forelimb movement. However, increased girth tightness resulted in a noticeable shift in saddle pressure towards the cranial (front) region of the back. This shift in pressure may be relevant, as it could contribute to discomfort or back-related issues over time. 📊

Overall, the findings indicate that although girth design and tension do not appear to immediately alter movement, higher girth tension can influence saddle pressure distribution, with potential implications for long-term comfort and performance. The main limitation of this study is the small number of horses.

When Care Conflicts With Performance

There is concern amongst the public, equestrians, animal welfare organisations, and horse-sport governing bodies regarding the welfare of performance horses 🐎⚠️, but equestrian culture appears slow to change.

The present study seeks to increase our understanding of human factors underlying the persistence of welfare-compromising management and training practices within the performance horse world 🧠📚. Individual, semi-structured interviews focused on equestrians’ attitudes were conducted with 22 equestrians from classical equestrian disciplines in the US, Canada, and the UK 🌍.

Five main themes were identified: perception of welfare issues; conflicting conceptions of a good life; objectification of the horse; instrumentalisation of horse care; and enculturation 🔍.

Participants perceived and were concerned about horse welfare, but expressed dissonance-reducing strategies, including trivialisation, reframing and justification 🤔. Participants shared conflicting conceptions of a good life and described how equestrian activities may infringe upon horse welfare.

Objectification of horses was among the attitudinal factors identified that may permit persistence of harmful practices, while the instrumentalisation of care theme showed how management practices often focused on performance and the horse’s job more than care about the horse 🏆➡️🐴.

Finally, enculturation (the process of adopting attitudes and behaviours of a culture) in equestrianism may be fundamental to maintaining practices and attitudes that compromise horse welfare 🧩.

These findings provide an enhanced understanding of why horse welfare issues persist in classical equestrian disciplines and may inform future human behaviour change strategies to promote improved horse welfare ✅📈.

This was an exploratory qualitative study meant to provide a foundation for future studies and not intended to be generalised across broader equestrian populations ⚖️.

How Early Is Too Early? Training Young Horses and Welfare Concerns

The early career start of racehorses, the pretraining of two-year-old Warmblood stallions for licensing, and individual housing of young horses raise animal welfare concerns 🐎⚠️.

This study assessed pretraining practices and trainers’ opinions on housing of young horses, minimum age to commence training and pretraining injuries 🧠📋.

Qualitative interviews with trainers of Warmblood stallions and Thoroughbred and Trotter racehorses (n = 10 each) were conducted 🗣️.

Pretraining of Thoroughbreds and Trotters began at 18 months, whereas licensing preparation of Warmblood stallions began at 29–30 months. For horses not achieving the expected results, procedures for Warmblood stallions differed from racehorses. Warmblood stallions not meeting expectations were often castrated and trained as riding horses, whereas Thoroughbreds and Trotters remained in training, but intensity was reduced.

Warmblood trainers did not report injuries requiring pretraining interruption. Thoroughbred and Trotter trainers suggested tendon damage as an occasional problem 🦵.

Group housing was not utilized because of the risk of injury due to agonistic behavior, especially among stallions, difficulty of individual feeding and disruption when horses were removed and returned. Straw bedding was used in 28 out of 30 yards and horses were fed 8–10 kg of hay/day 🌾. Except for three yards, horses were provided contact with neighbors through bars in stall walls.

Trainers largely fulfilled legal welfare requirements but horses had limited free movement and social interaction. None of the trainers agreed with the suggestion of a minimum age of 30 months for training ⚖️.

The study used semi-structured interviews, which are useful for exploring views but are limited by small sample sizes and researcher influence. Responses became predictable, suggesting sufficient interviews, but awareness of welfare debates may have shaped answers. Yard visits helped verify consistency between reported practices and observations 👀✅.

How Horses Spend Their Time — and Why It Matters

The time-activity budget is a key indicator of animal welfare ⏱️🐎. This meta-analysis integrated 14 studies (1979–2020) with 364 horses under wild, natural-living, and stabled conditions to evaluate feeding, resting, standing, and locomotion

The study aimed to categorize daily behavioural patterns in equines, with emphasis on feeding behaviour 🌱.

Feeding was greater

• in free-ranging (56 %) than stabled horses (38 %),
• in grouped (54 %) vs. isolated (39 %),
• in females (64 %) vs. males (48 %),
• and in grazing (56 %) vs. hay-fed horses (39 %).

Resting was higher

• in young, small, grouped, and grazing horses

Standing was more common

• in stabled, isolated, adult, larger, and hay-fed animals

Locomotion increased

• in free-ranging, grouped, and grazing horses
   

Management promoting foraging, social interaction, and locomotion enhances equine welfare

The study is limited by its small dataset, differences in behavioural measurement methods, and missing environmental details, which may introduce variability and restrict interpretation ⚖️. Its heavy focus on Northern Hemisphere research also limits how well the findings apply to global horse populations and management systems 🌍.

Why Social Contact Matters for Breeding Stallions

The obligation to ensure the welfare of domestic horses is evident 🐎⚖️. Social bonds are an essential part of the daily life of feral horses.

In human-controlled conditions, stallions usually live alone in a barren environment of individual boxes or paddocks, with contact to conspecifics limited to visuals. Still, many stallions do not have regular access to paddocks and pastures 🚧.

This provokes frustration and stress, which has been shown to contribute to the development of stereotypies, self-mutilations, abnormal sexual behaviour and reproductive problems ⚠️.

This review highlights how domestic environments may negatively diverge from the natural conditions necessary for the healthy behavioural development of stallions. We address stallions' welfare and reproductive problems that may arise from their lack of social contact.

These issues are discussed along the stages of a stallion's life under free-ranging conditions 🌿.

We postulate that today's breeding stallions must be enabled to enjoy the positive aspects of a bachelor stallion's life. This should include adequate consideration of the stallions' reproductive behaviour, including contact with a sexually receptive mare 🤍.

This will not only improve animal welfare but also ensure optimal semen quality and fertility ✅.

Can Humans Replace the Herd?

It is assumed that horses have a strong herd instinct that cannot be suppressed by any form of social support from humans 🐎👥.

The aim of this study was to assess the behaviour and heart rate parameters of horses that received various forms of human support during short-term social isolation 💓.

The research material consisted of 12 clinically healthy recreational Warmblood mares and geldings. The test was carried out four times 🔁.

The research test consisted of two parts, which began in the presence of accompanying horses and under conditions of social isolation, with and without support provided by a human (types of contact: tactile, vocal, tactile and vocal).

Behavioural observations were carried out on a five-point scale, and the heart rate parameters were measured 📊.

It was concluded that social support provided by humans in tactile, vocal, or tactile and vocal forms during the isolation of horses from the herd does not have very significant effects, especially in mares. The geldings respond much more favourably than the mares.

In addition, at this point in the research, it can be suggested that vocal support may have the best effects 🗣️. The more emotionally balanced the horses are, the more pronounced these effects should be ✅.

The study did not include stallions, young horses, different environments, or human influences on upbringing and training, so it is unknown how these unexamined factors might have affected the results ⚖️.

Do Horses Grieve the Loss of a Companion?

As a social species, it would be anticipated that horses may display altered behaviours toward dying or dead conspecifics 🐎💔. However, there is remarkably little literature on this subject.

The aim of this study was to identify behavioural changes in horses who have experienced the loss of a companion equid. An online survey was used to collect data on the housing and management of the equids, information on the surviving and deceased equid (including relationship), the passing of the deceased equid, and the type and duration of immediate and sustained behavioural changes in the surviving horse.

The survey was completed for 325 surviving horses. Horse owners reported multiple changes in behaviour in the surviving horse within 24 h of the companion’s death; most often related to arousal, behaviour directed towards other equids and people, alertness to stimuli and vocalisation.

Multiple logistic regression models indicate that horses who had shared an affectionate relationship, rather than simply tolerated each other, were more likely to change their excitement to interact with others or at feeding time and behaviour towards humans. These behavioural changes often persisted for 6 months after the death of their companion ⏳.

Horses who had witnessed the death of their companion were more likely to show alterations in time spent sleeping and feeding within 24 h of death, compared to before companion death. These surviving horses were also more likely to have a change in excitement towards interacting with others and/or around feeding time and vigilance 👀.

Whether or not the surviving horse had spent time with the dead body did not affect its behaviour in the first 24 h of loss. However, within 6 months after the death of the companion, horses who could spend time with the body had no change in vocalisation and excitement to interact with others and/or to feed time. Conversely, horses who could not spend time with the body were more likely to show a change in arousal and vigilance.

These findings indicate that horses may express grief-related behaviours, but further independent empirical evidence is required 📚. The death of a companion can have negative consequences for the survivor’s welfare, and this study may help owners manage emotional welfare better during this difficult time ❤️.

This study relied on owner-reported behaviours rather than direct observations, which introduces possible recall bias and the influence of owners’ emotional responses on the surviving horses' behaviour, despite efforts to minimise these effects through careful participant selection, “not sure” response options, and item-specific questioning ⚖️.

Can Sight, Touch, and Smell Really Detect Poor-Quality Hay?

Hay is a major part of a horse’s diet, but if it contains too much dust or is contaminated with harmful microorganisms like mould or bacteria, it can cause serious breathing problems 🐎🌾.

Horse owners and caretakers often check hay quality using sight, touch and smell, but it is unclear whether this simple method can detect hay that might be harmful.

In this study, researchers collected 50 hay samples from horse owners and examined them using both sensory examinations, as well as specific methods to measure dust levels and check for potentially harmful microorganisms.

The results showed that hay with an abnormal smell was more likely to produce high levels of dust, and hay with visible dirt or debris was more likely to contain potentially harmful bacteria or fungi.

This research highlights the value of basic sensory assessments as a rapid and low-cost means to monitor hay hygiene and protect horses’ respiratory health 💨.

Results should be interpreted cautiously given the modest sample size, subjectivity of sensory scoring, absence of clinical data, and limited explanatory power of the models ⚖️.

Forced or Free? How Choice Shapes Horses’ Responses to Touch

This study explored how therapy horses respond to different kinds of touch—patting, stroking, and scratching—on different body areas when the interaction is either forced or chosen by the horse 🐎🤝.

Ten therapy horses were touched by experienced and less experienced participants in two conditions: (1) forced touch, where the horse was tethered and the person had to touch all areas in a fixed sequence, and (2) free-choice touch, where the horse was loose and the person only touched the horse if it approached.

Horses showed more signs of discomfort—such as oral behaviours, restlessness, and tail swishing—during forced touch, although they shook their heads less in this condition. Tail swishing also varied by body area, being least frequent when the hindquarters were touched.

In the free-choice condition, horses were much more likely to hold their heads low and less likely to keep their ears focused on the person, suggesting a calmer, more self-directed posture.

Heart rate was higher during free-choice touch, but heart rate variability showed that horses were more physiologically relaxed with less experienced handlers. Overall, the findings indicate that forced touch was not perceived positively, emphasising the importance of giving therapy horses choice and control during equine-assisted services ✅.

This study examined how horses responded differently when touch was forced versus when they could choose to engage, but it did not separate the effects of touch itself from the influence of choice. Because all testing occurred outdoors on short grass, the horses’ natural grazing behaviour may also have affected how often they stayed within reach, highlighting the need for future research to isolate the effects of touch and choice more clearly ⚖️.

Do Stable Lights Affect How Horses Sleep?

Modern horse management often involves long periods indoors under artificial light, which may affect sleep and circadian rhythms 🐎💡.

This study compared the effects of a customised LED lighting system (blue-enriched light by day, dim red light at night) with standard fluorescent lighting on sleep, blink rate, and circadian gene activity in ten riding school horses.

Behaviour, blink rate, and hair samples were recorded over four weeks in a cross-over design 🔄.

Lighting type had no effect on total sleep, recumbency, wakefulness, or clock gene expression, though horses under LED light showed slightly more daytime wakefulness.

Dim red night lighting did not disrupt normal sleep or rhythms, suggesting tailored LED systems may support healthy day–night cycles in stabled horses 🌙.

However, results should be interpreted cautiously due to the small sample size, individual variation in sleep behaviour, and possible exposure to natural light during the control phase ⚖️.

Life After Racing: What the Data Tell Us About Former Racehorses

Owner/keeper submissions for 8,256 horses were analysed 🐎📊 and extrapolated to a national estimate of ~33,600 former racehorses, of which ~80% are currently traceable.

While 98% of horses held passports 📘, only 64% were registered in the current owner’s name despite 90% awareness of the requirement.

Most horses were owned (91%), predominantly geldings (74%), aged 5–14 years, and used mainly for leisure, hacking, or unaffiliated competition 🏇.

Respondents expressed strong support for digital identification/e-passports 💻, but knowledge gaps and variable compliance were evident—particularly around change-of-ownership and notification of death.

These data provide a baseline to strengthen lifetime traceability, guide education and policy 📚, and evaluate aftercare outcomes over time.

However, as a single time-point, self-reported dataset with uneven response to sensitive items, results should be interpreted cautiously ⚖️ and validated with repeat censuses and complementary qualitative work.

Are Riding Lesson Horses Really Worse Off?

Riding lesson horses have generally poorer welfare than other types of horses. 🐴 A survey was distributed to operators of Canadian riding lesson facilities to identify management trends that may influence the welfare of lesson horses, as well as to understand the demographics of the Canadian lesson herd and the people responsible for their care.

📋 The survey received 154 responses representing 13.2% (n = 1550) of the total estimated Canadian lesson herd. Tests determined relationships among quantitative responses and thematic content analysis analyzed qualitative responses. Responses suggested that Canadian lesson horses largely receive species-appropriate care with daily access to group turnout and regular attention from veterinarians and farriers.

🌱👩‍⚕️🦶 A high level of concern for the health and comfort of lesson horses was demonstrated through use of complementary and alternative veterinary medicine, dietary supplements, joint injections, and/or ulcer and pain-management medications.

💊🩺 Qualitative responses highlighted financial challenges and client expectations as significant obstacles to ensuring the welfare of lesson horses.

💰⚠️ This increased understanding of the landscape of the Canadian riding lesson industry provides new avenues for further research, suggesting that the reportedly poor welfare of lesson horses may not be related to management but other factors unique to the life of lesson horses.

🔍 This study is limited by typical survey biases—including self-selection, nonresponse, misinterpretation of questions, regional sampling imbalance, and low engagement from several provinces and territories—which may affect how representative the results are of the wider Canadian lesson industry. 📝⚠️

🔥 For the first time ever, AI has successfully decoded horse emotions from their faces.

Animal affective computing is an emerging new field, which has so far mainly focused on pain, while other emotional states remain uncharted territories, especially in horses. 🐴💭

This study is the first to develop AI models to automatically recognise horse emotional states from facial expressions using data collected in a controlled experiment.

🤖📹 They explore two types of pipelines: a deep learning one which takes as input video footage, and a machine learning one which takes as input EquiFACS annotations. The former outperforms the latter, with 76% accuracy in separating between four emotional states: baseline, positive anticipation, disappointment and frustration.

📊 Anticipation and frustration were difficult to separate, with only 61% accuracy. 😬

However, results should be interpreted cautiously given the study’s context-specific design, unmodelled individual factors (e.g., breed, age, sex), and limited generalisability beyond the experimental setup. There are also a limited number of EquiFACS Facial Action Units (FAU) that are needed to associate with a specific affective state, so the training of the AI system may have gaps or flaws. ⚠️🔍

Did you know rein type could almost double rein tension?

Rein tension can affect the comfort and performance of vaulting horses.

This study measured rein and lunge line tensions in 39 international-level horses cantering with different rein types permitted by FEI rules, including side reins with or without elastic, fully elastic reins, draw reins, and reins fixed to the noseband (see the paper for equipment classification). Rein type significantly influenced total tension, which ranged from 6.2–11.7 kg, with right-side tension consistently higher.

Greater tension was associated with increased mouth opening, a behavioural sign of discomfort.

Draw reins produced the lowest total tension and least mouth opening, though individual differences remained high.

These results highlight that rein type affects both tension and comfort, reinforcing the importance of appropriate rein selection for horse welfare.

However, as some horses were unfamiliar with certain rein types and surface conditions varied slightly, further research is needed to confirm these findings under standardised conditions.

Stereotypic behaviours, such as crib-biting and weaving, can be seen in horses kept under restrictive management, but their physiological basis remains unclear. 🐴

This study investigated whether stress-related salivary biomarkers differ between Thoroughbreds with and without stereotypies.

🧪 Saliva was collected at rest from three groups: ten high-level competition horses without stereotypies, eleven high-level competition horses showing stereotypies, and five non-competing leisure horses with stereotypies. Cortisol concentrations were highest in competing non-stereotypic horses, suggesting that intense training may elevate stress hormone levels.

📈 In contrast, alpha-amylase (sAA) activity was significantly higher in non-competing stereotypic horses, indicating heightened sympathetic nervous system activation.

⚡ Butyrylcholinesterase (BChE) activity did not differ between groups. These findings suggest that both competition level and stereotypic behaviour influence physiological stress responses, supporting saliva biomarkers as valuable non-invasive welfare indicators in horses.

🧬 The small sample size and lack of repeated measures mean this finding should be interpreted cautiously. ⚠️

🐎 Equestrians offer a pivotal avenue of rehoming for Thoroughbred horses that retire from the racing industry.

However, behavioural attributes considered advantageous in racehorses may be inappropriate in equestrian mounts. Understanding the behaviour of off-the-track Thoroughbreds (OTTTBs) is critical to the welfare and safety of horses and handlers. 🧠💛

This study explored behavioural characteristics in OTTTBs compared with other ridden horses, using owner-observed information from the Equine Behaviour Assessment and Research Questionnaire (E-BARQ) database. Behaviours associated with boldness, compliance, rideability, trainability, and responsiveness to acceleration and deceleration signals were analysed. 📊

OTTTBs demonstrated more boldness, with lower compliance and responsiveness to deceleration signals, than other horse breeds in this study. ⚡🐴 These findings illustrate both the equestrian potential of OTTTBs and the behavioural challenges they can present. The study highlights the importance of further research into the relative influences of breed and life experiences on behaviour in OTTTBs, to enable training and management practices to be evidence-based for enhanced equine welfare. 🔍📚

Results should be interpreted cautiously given the potential for self-reporting and sampling biases, as well as the inability to infer causality between temperament, experience, and behaviour within the scope of this study. ⚠️

🐴 Feeding strategies must meet horses’ needs without compromising welfare, especially in group housing where limited hay can cause aggression and injury.

🌾 This study compared three feeding regimes in 18 mares: traditional (three 2-hour daytime meals), portioned (six 1-hour meals across 24 h), and ad libitum slow-feeding with hay nets.

🧠 Horses using slow-feeders showed activity time budgets resembling natural conditions, while portioned feeding appeared more frustrating, showing no reduction in agonistic behaviours and reduced lying time by approximately 11 min/day compared with other systems.

💚 Traditional and slow-feeding regimes supported calmer interactions.

⚖️ Portioning into smaller, frequent meals did not reduce stress, while slow-feeding emerged as a more suitable, welfare-friendly strategy that warrants further investigation.

📊 As the study was short-term and limited to mares in small groups, further research is needed to confirm these findings under varied conditions.

🐴 Horses can regulate their own exercise intensity, influenced by social and motivational factors.

🎥 This study tested whether seeing another horse trotting would increase effort.

🐎 Seven horses completed a 2×2 crossover trial after treadmill familiarisation, viewing either a trotting horse video or a racetrack image without horses.

❤️ When shown the trotting horse, heart rate, plasma lactate, and alert behaviours (ears forward, raised head angle) increased significantly compared to control conditions.

🧠 The visual stimulus was well tolerated and activated anaerobic lactic pathways, suggesting horses perceived and adapted to a social environment.

👀 These results indicate that social visual cues can safely encourage forward movement, offering a welfare-friendly alternative to whip use.

⚖️ However, because treadmill speed could not be freely regulated and researchers were not blinded to conditions, further studies are needed to confirm these findings and assess how horses self-regulate movement in social contexts.
