🐴Hypermobility in breeds where you wouldn't expect it
Hypermobility doesn't only occur in long-lined, long-legged sport horses. It also appears in breeds that look robust and compact. In fact, it often occurs in these breeds.
Examples include the Friesian horse, Irish cobs, and various types of draft horses. The Friesian horse has been increasingly refined over the last 30-50 years, developing from a “work horse” into a sport horse. This could be an explanation for the increased hypermobility. In Irish cobs and different draft horses, there hasn't been a selection for sport qualities in particular. The original horse has been largely preserved, yet we still see an increase in hypermobility.
All these horses show the same hypermobility traits as sport horses: hypermobility in the spine, the pastern joints, and possibly in the other leg joints.
One characteristic is quite specific to the robust workhorses; that is how the tissue feels. The tissue is softer, more fluffy-like. This says something about the amount of collagen fibres (connective tissue) in the muscles.
Young animals have relatively little connective tissue in their muscles, which is why veal is more tender than the meat of an adult cow. As the animal gets older, more connective tissue develops, creating thicker layers and making it stiffer.
You feel this as tissue resistance. This is different from tonus (tension) on the tissue.
Muscle tissue with few collagen fibres feels softer and provides less stability. This means the horse has to work harder with its muscles to stabilize its body and this is a tough job because the body of a draft horse is relatively heavier than that of a sport horse.
This means stabilization takes more energy, and the horse can handle less load.
In addition, hypermobility can cause all sorts of other issues related to, for example, sugar metabolism, the immune system, and the nervous system. So if your horse has complaints that are hard to explain, it's a good idea to keep hypermobility in mind, even with robust draft or draft-like horses.
