My mission is to always advocate for the horse and to constantly strive to enhance the quality of life for horses and their owners, through a compassionate, evidence-based osteopathic approach.
I strongly believe in the interconnectedness of the whole horse, and that the body, the mind and the spirit are inherently linked, creating a delicate balance that must work harmoniously, in order to achieve true health and wellbeing. I believe that all these elements need to be fully nurtured and understood, for a horse to thrive with resilience and good health, which in turn leads to strongly bonded harmonious partnerships with their human companions.
I am hugely passionate about promoting the longevity of horses and I seek to empower horse owners with the most up to date knowledge and resources, while fostering a nurturing environment that promotes healing, comfort and overall health.
Where required, I will always challenge and discredit the numerous myths that exist within the horse industry and I will always encourage owners to ask themselves why, when things are not going right! Horses do speak to us in their own language, if only we are willing to listen! It is my mission to give your horse a voice!
Expert Care
I am extensively trained and experienced, with a well-rounded education and approach to equine health.
Compassionate Environment
I treat every horse as if they were my own, providing a calm, relaxing and supportive atmosphere.
Client Education
I believe informed horse owners make the best decisions for their horses, and I’m here to guide you.
Join me in my commitment to holistic equine healthcare. Together, we can ensure your horses lead happy, healthy lives.
I offer a range of evidence-based equine services designed to support your horse’s unique needs, including:

𝗟𝗮𝗺𝗲𝗻𝗲𝘀𝘀 𝗱𝗼𝗲𝘀𝗻’𝘁 𝗮𝗹𝘄𝗮𝘆𝘀 𝗹𝗼𝗼𝗸 𝟯-𝗹𝗲𝗴𝗴𝗲𝗱!! 🙈I have just watched a sales advert for a horse, which prompted me to write this post! 🥴The horse is essentially being advertised as a very quiet, very slow-going type, who is happiest taking life at a very leisurely pace. Having watched the sales video though, I see something very different! 😬😵💫To my trained eye, the horse appears lame on multiple limbs. His movement is short, restricted and laboured. He looks extremely tense through the body and despite being asked to do very little work in the video, he is noticeably huffing and puffing.Then underneath the ad, all the comments are positive 🫣“He’s fabulous.”“Beautiful horse.”“How much?”“What a lovely boy.”And, being truthful, I find it quite astonishing! 😳🫣 … But then again, maybe I shouldn’t! 😔Research suggests that more than 47% of sport horses in normal work may be lame, with that lameness going unrecognised by their owners or trainers.When you consider that, then maybe a comment section full of people admiring a horse whose movement, to my eye, is very clearly abnormal, shouldn’t be surprising at all! 🤷♀️I also think that it raises a much bigger welfare issue. … How many horses are being described as lazy, slow, reluctant, lacking impulsion, or on the opposite end of things ~ difficult, cold-backed, or “that’s just how he moves”, when what we are actually looking at is musculoskeletal discomfort? 🙈😔Lameness recognition is not just about being able to pick out the lame leg. Sometimes the first, and most important skill, is recognising that the horse in front of you is not moving comfortably, or in any way normally at all!And it struck me just how common it is that significant gait abnormalities are being missed when a horse isn't obviously hopping lame on one leg! 😢I don't personally believe there is such a thing as a lazy horse. There is likely to be good reason a horse like this is reluctant to go forward. That reason may not always be pain, but surely our first response should be to ask "why", rather than to simply conclude that the horse is lazy.Pain, weakness, fatigue, poor balance, lack of fitness, fear, confusion, poor saddle and tack fit and learned behaviour can all look like a reluctance to go forward.And, sometimes what gets described as a lovely, quiet “plod” may actually be a horse that finds movement very physically difficult.Before we label the horse, we need to question such behaviour. Lameness does not always present as a dramatic head nod, or a horse barely able to weight-bear. When more than one limb is involved, particularly with bilateral or multilimb problems, the picture can be much less obvious. Instead of seeing one clearly lame leg, you might see a horse that is generally short-striding, stiff, guarded, reluctant to go forward or simply moving as though everything is really hard work! … And because there isn't one leg screaming “THIS ONE”, the movement is inclined to be interpreted as the horse being lazy, quiet, a plod, slow or just “that type”.That is why I think we need to stop judging soundness by asking "which leg is lame?” The important question is "does this horse move like a comfortable horse?” In the horse I watched today, my answer would unfortunately be a big fat NO! 😢Obviously, nobody can diagnose the cause of lameness from a sales video. A proper veterinary examination would be required for that. But we absolutely can recognise abnormal movement, tension, restricted gait and signs that warrant further investigation.Maybe it's time that basic lameness and pain recognition should be a compulsory part of learning to care for horses.… Always ask yourself WHY!! ❤️🐎❤️

In some horses, adjacent processes can come into contact or can overlap, potentially resulting in bony changes, inflammation and pain. However, radiographic evidence of kissing spine does not always mean that a horse is experiencing clinical back pain.A young horse needs adequate nutrition, progressive conditioning and sufficient muscular development to support and stabilise the spine. The abdominals, multifidus and other epaxial muscles all contribute to dynamic stability of the thoracolumbar region.A weak, poorly conditioned youngster is more likely to fatigue and struggle to maintain appropriate posture under load. If that horse is repeatedly worked beyond its level of strength and conditioning, especially under saddle, it may spend more time travelling with the thoracolumbar spine in extension, a position that reduces the space between the dorsal spinous processes.Add to this inadequate nutrition and poor topline development during a period of growth and you have a horse being asked to tolerate repetitive mechanical loading without the muscular development and conditioning we would ideally want to support that workload.Kissing spine is, as I said, multifactorial and radiographic changes can also be found in horses without clinical back pain, interestingly. Conformation, breed, genetics, saddle fit, rider influence, training, concurrent lameness and many other factors can be involved.Understanding the different factors that can influence spinal health is vital during a horse's growth and development, when the musculoskeletal system is still maturing.Young horses need time to grow, adequate nutrition to develop and progressive conditioning to build the muscular strength that's needed to support a healthy, functional back as they mature. Their backs are no exception to the demands of growth and development.𝐑𝐞𝐟𝐞𝐫𝐞𝐧𝐜𝐞𝐬Pilati, N., Pressanto, M.C., Palumbo Piccionello, A., De Angelis Corvi, F. and Beccati, F.

𝗪𝗵𝘆 𝗰𝗵𝗮𝗳𝗳 𝗵𝗮𝘀 𝗮 𝘃𝗮𝗹𝘂𝗮𝗯𝗹𝗲 𝗽𝗹𝗮𝗰𝗲 𝗶𝗻 𝗮 𝗵𝗼𝗿𝘀𝗲'𝘀 𝗱𝗶𝗲𝘁I recently came across a social media post suggesting that chaff has no place in a horse's bucket feed. As an equine nutritional consultant and veterinary nurse, I disagree and the current scientific evidence doesn't support such a blanket statement either.The foundation of good equine nutrition is simple – feed a forage-based diet that is high in fibre, low in sugar and low in starch.So the question is …If fibre is exactly what we should be feeding horses, why then would it suddenly become a bad thing just because some of it is placed in a bucket?Good-quality chaff is chopped forage. Whether it's grass, alfalfa or straw, it is still a source of fibre. It doesn't stop being forage because it's shorter in length.When used appropriately, chaff can increase the fibre content of a bucket feed, encourage horses to chew for longer, slow down greedy eaters and increase saliva production. That extra saliva helps to buffer stomach acid and supports normal digestive function.Alfalfa deserves a special mention, as it naturally contains higher levels of calcium and protein than many other forages and research has shown it can help buffer stomach acid, making it a useful dietary component for many horses prone to equine squamous gastric ulcers.Another benefit is that fibre can provide an alternative source of energy to cereal starch. Rather than cereal based diets, nutritionists prefer to obtain as much energy as possible from digestible fibre where appropriate, keeping the overall diet more in line with the way horses have evolved to eat.What about choke?Choke is sometimes mentioned whenever chopped fibre is discussed, but the evidence doesn't suggest that good quality chaff is, by itself, a common cause of choke. Choke is usually multifactorial, with factors such as poor dentition, bolting feed, inadequate chewing, dehydration and previous episodes of choke all increasing the risk. Good feed management is key. Personally, I always prefer to dampen bucket feed with water, particularly for older horses, greedy eaters and those with compromised dentition, in order to encourage slower eating and to produce a softer feed.Of course, not every chaff is the same. Grass chaff, alfalfa chaff and straw chaff all have different nutritional properties. Some products are molassed, while others are not. Choosing the right one for the individual horse is important. Likewise, not every horse has the same nutritional requirements. A veteran with poor teeth, a performance horse, an overweight native pony and a horse with PPID or Equine Metabolic Syndrome should not all be fed the same feed.Good-quality chaff has a valuable place in many horses' diets. The key, as with any feed, is in choosing the right product for the right horse. That's what evidence-based equine nutrition is all about ❤️🐎❤️𝐑𝐞𝐟𝐞𝐫𝐞𝐧𝐜𝐞𝐬Committee on Nutrient Requirements of Horses (2007) Nutrient Requirements of Horses. 6th edn.

When one limb becomes painful, the horse instinctively redistributes its weight and alters the way it moves in order to protect that area. Initially, this might simply change the horse's gait. However, if the primary problem persists, the extra load placed on other limbs and tissues can eventually lead to true compensatory pain and lameness elsewhere.This means that a horse can present with a genuine forelimb lameness, while the primary issue actually originates in a hindlimb, or vice versa, for example. As equine therapists, this shows how important clinical reasoning is. Rather than asking, "Which limb is lame?", we must also ask "Is this the primary problem, or is it a compensation?"The equine body functions as an interconnected system. Pain in one region can influence posture, muscle function, proprioception, movement patterns and load distribution throughout the body. Muscles, fascia and joints do not work in isolation, they all work together.This is why a thorough assessment should always consider the whole horse, not just the area that first catches our attention. Static assessment, dynamic assessment, movement quality and the horse's overall posture all provide us with valuable pieces of the puzzle.There are recognised compensation patterns, often referred to clinically as 'the law of sides', which can help explain how pain in one limb influences movement elsewhere. These patterns are valuable clinical guides, but they are definitely not absolute. Every horse compensates differently depending on the nature of the injury, its duration, the horse's conformation and many other factors.When we focus only on the obvious lameness, we risk treating the consequence rather than recognising the primary source of dysfunction.Our role is not to jump to conclusions, but to think critically, assess systematically and appreciate that the horse's body is a connected, adaptable system.Sometimes, the answer isn't in the limb that looks lame but in understanding why that limb has become lame in the first place ❤️🐎❤️𝐑𝐞𝐟𝐞𝐫𝐞𝐧𝐜𝐞𝐬Persson-Sjodin, E., Hernlund, E., Pfau, T., Andersen, P.H., Forsström, K.H., Byström, A., Serra Bragança, F.M., Hardeman, A., Greve, L., Egenvall, A. and Rhodin, M.

"𝗜𝘁'𝘀 𝗼𝗻𝗹𝘆 𝗯𝗿𝗶𝗱𝗹𝗲 𝗹𝗮𝗺𝗲𝗻𝗲𝘀𝘀" … 𝗥𝗲𝗮𝗹𝗹𝘆?!This is a phrase that is unfortunately still heard in the equestrian world, but it's also one that can be misleading. It refers to the belief that some horses are not truly lame but that the rider, the bridle, or the tack somehow creates the appearance or illusion of lameness. In other words, if the horse only looks lame under saddle, it isn't considered a "real" lameness 🫣Well current evidence suggests otherwise. When a horse is ridden, its posture, balance and movement change. The additional weight of the rider, together with the demands of working in a contact, bending, collecting and engaging the hindquarters, places different loads on the musculoskeletal system. If there is an underlying orthopaedic problem, these changes can simply make it more apparent.The bridle or the rider does not create the lameness. Instead, ridden exercise can reveal an underlying problem that isn't as obvious when the horse is loose, on the lunge, or moving without the weight of a rider.This is why it is important that horses that are "only lame when ridden" deserve careful veterinary investigation rather than having their signs dismissed. These cases are more common than many people realise.Research by Dr Sue Dyson and colleagues has transformed our understanding of the ridden horse. Many behaviours once labelled as naughtiness, resistance, or poor training are now recognised as potential indicators of musculoskeletal pain. A thorough assessment should consider the horse, the tack, the rider, and the way they interact, but the possibility of genuine pain should never be overlooked.Our horses communicate through the way they move. Sometimes they whisper before they shout. The question is… are we listening? 🤔

Often I can see lameness, biomechanical compensation, suboptimal management, or the nutritional gaps, for example, that have been dismissed as "normal". … but sometimes, the moment I suggest that a "naughty" horse could actually be in pain, or that the current management could possibly be fueling the very problem they want me to "fix," the mood can shift 😔 It can be an awkward, isolating spot to be in! 😔🫣However, I'm not there to be liked; I am there to advocate for the horse, no matter how exhausting it can be when the people who hired me for my professional input suddenly don't want to hear it, because it challenges the very way they’ve always done things! It can be very frustrating to watch people reach for a band-aid ~ a stronger bit, a pair of draw reins, punishing behavioural reactions instead of considering physical or emotional stress, a quick-fix, when I know there’s a root cause beneath the surface that needs to be addressed … but the thing is ~ I simply cannot un-see it! 🫣🧐👀Once you look at the scientific evidence, at the actual biology and physiology of the horse, you can’t just ignore the obvious. I know without a doubt that if we don't address the root cause, nothing actually changes for that horse, except maybe temporarily. And if I don’t speak up, then who will? The horse certainly can't! 🤷♀️😔It can be a lonely path being the one who refuses to play along with "tradition" when it is in fact, failing the animal 😔 Science allows us to move beyond assumption, habit and anecdotal evidence, and instead lets us to make decisions based on what is objectively shown to improve the horse’s quality of life. Following the evidence base does not mean abandoning experience; it means combining experience with critical thinking, curiosity and a willingness to evolve when new information emerges. I fully intend to keep educating myself and to keep following the scientific evidence, because that is the only way we can truly progress.I know that change can be hard and it can be uncomfortable. Nobody likes it and almost everyone tries to avoid it, often clinging to the old status-quo because it definitely feels safer and dare I say easier! Sometimes, we cling to these 'old ways' because they were taught to us by our mentors who we deeply respected and challenging them can feel like a personal attack on our history, or our teachers. But time and time again, I see that the changes we fear are the very ones that lead us to a better, healthier life for the horse. It isn't easy to challenge how things are done, but growth is rarely comfortable 😱I believe that the equine industry will only move forward when we stop being afraid of making people uncomfortable. When we start thinking deeper and stay open-minded. When we question ourselves and always ask ourselves "why"! … Because for our beloved horses, it’s the only way forward!! ❤️🐎❤️
𝗪𝗶𝗻𝗱-𝗦𝘂𝗰𝗸𝗶𝗻𝗴 𝗶𝗻 𝗛𝗼𝗿𝘀𝗲𝘀: 𝗠𝗼𝗿𝗲 𝗧𝗵𝗮𝗻 𝗝𝘂𝘀𝘁 𝗮 '𝗕𝗮𝗱 𝗛𝗮𝗯𝗶𝘁'Behaviours such as wind-sucking and crib-biting are often dismissed as simply a “bad habit” or boredom behaviour in horses. However, the scientific evidence suggests the picture is far more complex than that. These behaviours are classified as stereotypic behaviours. That is repetitive behaviours that are thought to develop in response to factors such as stress, management, feeding practices, or a reduced ability to perform natural behaviours.Research has shown a significant association between wind-sucking/crib-biting and gastric disease, particularly Equine Gastric Ulcer Syndrome (EGUS). While not every horse that windsucks will necessarily have ulcers and not every horse with ulcers will windsuck, the relationship between gastric health and stereotypic behaviour is considered very important.The current thinking is that in many cases, wind-sucking develops secondary to factors such as:□ Gastric irritation or ulceration□ High concentrate/high starch diets□ Restricted forage intake□ Stable confinement □ Stress and frustration□ Altered digestive comfortFor years, it was often believed that wind-sucking itself caused ulcers. However, modern evidence supports the opposite direction more strongly, that is that gastrointestinal discomfort and management factors may contribute to the development of the behaviour in the first place.Interestingly, wind-sucking can also have a self-soothing effect for the horse. Studies suggest it can increase saliva production, potentially helping to buffer stomach acid, while also influencing stress and reward pathways within the brain. This could help explain why some horses continue to perform the behaviour even after ulcers or management issues are addressed.This is one reason why simply preventing the behaviour mechanically (for example with anti-cribbing collars) without considering the horse’s overall management, diet, forage intake, stress levels and gastric health may fail to address the underlying issue.In many cases, these horses benefit from a more holistic review of: • Feeding practices • Forage availability • Starch intake • Turnout and social interaction • Stress levels • Gastric health • Musculoskeletal comfort and painAs always, every horse is an individual and wind-sucking is more likely to be multifactorial rather than having one single cause. Still, it is important that we move away from the outdated idea that these horses are simply performing a meaningless "bad habit." The behaviour itself may not be the problem, but rather a clue to something deeper.𝐑𝐞𝐟𝐞𝐫𝐞𝐧𝐜𝐞𝐬 Nicol, C.J., Davidson, H.P.B., Harris, P.A., Waters, A.J. and Wilson, A.D.

𝗘𝗾𝘂𝗶𝗻𝗲 𝗚𝗮𝘀𝘁𝗿𝗶𝗰 𝗨𝗹𝗰𝗲𝗿 𝗦𝘆𝗻𝗱𝗿𝗼𝗺𝗲 (𝗘𝗚𝗨𝗦)Equine Gastric Ulcer Syndrome (EGUS) is something most horse owners have heard about but recognising the signs can be challenging, as they can be vague and non-specific.The only way to definitively diagnose gastric ulcers is through veterinary gastroscopy (scoping). However, horses will often give us good clues that something may not be quite right. The more signs present together, the more suspicion it can raise that ulcers may be at play.Possible signs associated with EGUS can include:• Poor performance• Reluctance to go forward• Behavioural changes or becoming “grumpy”• Girthiness• Sensitivity around the abdomen• Resistance during ridden work• Tail swishing, ear pinning• Tension• Difficulty maintaining condition or weight loss• Dull coat• Reduced appetite or picky eating• Leaving hard feed unfinished• Eating hay but avoiding concentrates• Mild recurrent colic• Teeth grinding• Excessive salivation• Changes in temperament• Poor topline development• Intermittent loose droppings• Stressy or anxious behaviour• Reduced willingness to work• Spooking or overreactivity• Lying down more often than normal• Poor recovery from exerciseSome horses with ulcers show very obvious signs, while others can appear almost completely normal. Equally, many of the signs listed above can also occur with several other conditions including orthopaedic pain, dental disease, poor saddle fit, inappropriate management, stress, or other medical conditions.This is why it is so important not to jump straight to assuming “ulcers” without proper veterinary investigation.Risk factors that can contribute to EGUS can include:• High starch diets• Long periods without forage• Lack of turnout• Stress• Changes in environment/routine, or major life changes e.g. changing homes• Stereotypical behaviours e.g. windsucking • Intensive training• Frequent travel• Heavy competition schedules• Chronic pain or discomfort elsewhere in the body• Illness• NSAID (non-steroidal anti-inflammatory drug) use• Multiple handlers/caregiversThe horse’s stomach was designed for near-constant forage intake. Modern management often challenges that system significantly.If you suspect ulcers, speak with your vet. Gastroscopy remains the gold standard for diagnosis and allows for appropriate medical treatment, as well as management changes that should be put in place.

𝗦𝗶𝗺𝗽𝗹𝗲 𝗮𝘀! 🤷♀️Because the horse is a biotensegrity system, his structure is maintained by continuous soft tissue tension (muscle, tendons, ligaments & fascia), with bones acting as compression struts (Levin, 2002; Schleip et al., 2012). This means that the horse's muscle doesn’t just create movement, it creates and maintains the actual structure itself. So when the muscle isn’t there, the horse doesn’t just lose strength, he loses stability, ability to distribute load, force transfer and shock absorption. In other words, he loses the ability to function under athletic demand. So it's not that he will just be less developed and it's not that he will just need a bit of topline, or some manual therapy; he simply cannot perform as an athlete! When the system is underdeveloped, the body cannot organise itself effectively under load. The thoracic sling loses its ability to support the trunk, resulting in a dropped posture through the forehand. The back is no longer able to stabilise and transfer force efficiently, so instead of transmitting energy from the hindlimbs forward, that energy is dissipated through the system. The hindlimbs may still be able to generate force, but without a stable and co-ordinated system to receive and transfer it, that force is not used effectively. As a result, load becomes unevenly distributed, increasing stress on certain structures and leading to compensation. This is not simply a training issue, but a serious structural limitation, with a system that cannot organise or support itself under load … and if the system cannot do that, then it simply cannot perform. Not because it won’t, but because it physically can’t.Research into fascial and musculoskeletal systems supports this, showing that the body functions as an integrated tension network, not as isolated parts (Schleip et al., 2012; Elbrønd, 2015).A horse is not born an athlete, it becomes one through appropriate, repeated biological stimulus. The same also applies to human athletes. No one is born with the strength, co-ordination and load tolerance required for performance; these are developed over time through progressive training, adequate nutrition and adequate recovery. Horses should be treated no differently. The musculoskeletal system is biologically active and adapts to the demands placed upon it. Muscle, tendon, ligaments, fascia and bone all require appropriate, repeated loading, in order to develop the strength, co-ordination and resilience necessary for performance. Without this normal stimulus, the system remains underdeveloped and unable to support athletic function.Although manual therapy can improve comfort and movement quality, it does not build the tissue required for performance. There is absolutely no shortcut around this. Tissue capable of performance can only be developed through progressive loading, appropriate nutrition and time for adaptation.”While much of the foundational work on biotensegrity and fascial networks originates from human research, these principles also apply directly to the horse and are increasingly reflected in equine-specific models of locomotion (Elbrønd, 2015).𝗥𝗲𝗳𝗲𝗿𝗲𝗻𝗰𝗲𝘀Elbrønd, V.S. and Schultz, R.M.
