![]() The front feet are usually most severely affected, but 1 or all 4 may be variously affected. Trembling, sweating and anxiety are sometimes observed. ![]() There will be a strong or bounding digital pulse, and the hooves feel warm, indicating increased blood flow. This is most noticeable if the horse tries to turn around. The horse or pony tries to transfer body weight on to the heels and hind legs, by standing with the forelegs well out in front of the body, and the hind feet up under itself with an arched back. Usually, as the pain in the feet increases, an active horse stops moving about, stays in the one place in the paddock, or is observed lying down at an unusual time of the day. The horse lifts one foot then another unable to get comfort on any foot for very long. Some owners notice the horse is shuffling its feet this is a classic laminitic sign and should always be investigated. With very mild laminitis a change in normal behavior may be all that is noticed, and it can take some time before anyone realises you are dealing with a laminitic horse. With severe laminitis it is clear that something is wrong because your horse will be obviously uncomfortable, even if you do not realise at first what the problem is. DO THIS WHILE YOU ARE WAITING FOR THE VET. THIS IS THE TIME WHEN COLD THERAPY (ICE AND WATER) FOOT BATHING IS MOST EFFECTIVE. NEVER WAIT UNTIL THE NEXT DAY TO RING THE VETERINARIAN DO IT AT THE VERY FIRST SIGNS, EVEN IF YOU ARE UNSURE WHETHER IT IS LAMINITIS. IN ALL CASES OF LAMINITIS, IF THE ACUTE PHASE CAN BE KEPT TO 12 HOURS OR LESS, DAMAGE WITHIN THE FOOT WILL BE GREATLY REDUCED. Laminitis causes unrelenting pain and a characteristic, often severe lameness, usually worse in the front feet. Shearing forces damage the arteries and veins, and the corium of the sole is crushed as the bony column of the limb descends deeper into the foot and the hoof capsule slides up over the pedal bone. The weight of the horse and the forces of locomotion drive the pedal bone down into the weakly attached hoof capsule. This leads to partial or complete separation of the laminitic bond.ĭetachment of the laminae (laminitis) allows a variable amount of movement of the hoof capsule around the pedal bone. Therefore, laminitis the disease would be better described as “acute laminar degeneration” which is due to a complicated, interrelated sequence of events including enzymatic breaking of the bonds between the sensitive and insensitive laminae. The outer hoof capsule can no longer suspend the rest of the foot within it. A comparison is walking through the sole of a pair of shoes or wearing through your socks. This accurately describes the phenomenon of the pedal bone sinking lower in the hoof capsule due to the horse’s own body weight tearing the weakened laminae. Founder means to send to the bottom to sink (like a ship). However, many horses experience inflammation of these structures without developing the acute disease and chronic changes we all recognise as laminitis.įounder and laminitis are exactly the same disease process. Laminitis is inflammation of the sensitive laminae of the hooves. The function of the laminae is to bind to each other and to keep the pedal bone suspended within the hoof capsule, and to allow for normal hoof wall growth over the stationary bone. The sensitive laminae attached to the pedal bone, and the insensitive laminae attached to the inner hoof wall. There are two types of laminae in the horse’s foot. I hope that information within this site will be of help to you. I travel widely to teach or assist horse owners with farriery issues whenever I can. I am currently working in my own mixed practice in Victoria, Australia and maintain a small number of farriery clients. My goal is to pass what I am learning on to you for the benefit of your horses. “The more I know, the more I know I don’t know”. The wide range of horses I have handled, the many jobs I’ve had and the countries I have visited has enhanced my basic foundation of horse knowledge. Throughout this time I supported myself solely by farriery, and since graduation the mix of farriery and veterinary has been very rewarding. Then, in my mid 30’s, I decided to return to school and complete year 12 and then put everything into becoming a Veterinarian. I performed a wide variety of equine work including mustering, droving, clipping racehorses, yearling preparation, stud work and held an owner/trainer’s license before settling into farriery in my late 20’s. I was foaled in 1962 in Victoria and left school to work in the horse industry.
