Navicular Disease Is A Serious Problem
Horse owners rightly fear the problem of founder in their animals. One cause of navicular disease, foundering usually affects the front feet of a horse, resulting in lameness which can be permanent. There are other causes of navicular problems which are still being researched by equine health experts.
The term 'founder' is used to describe the discomfort a horse experiences when it eats too much rich grass or grain. The result is an inflammation of the digestive tract and of the front feet of the animal. Severe cases can result in death and/or permanent damage to the feet. A horse allowed unlimited access to lush grass or the feed room can quickly develop symptoms of founder.
Horses allowed to get too fat are also at risk. Overweight animals are prone to foundering. Excess weight also puts undue, constant stress on the feet, especially the front ones which naturally bear most of the animal's weight.
Although ponies are more susceptible than horses to grass founder, all equines are at risk. Maintaining a proper weight is important, since keeping a horse in a dry lot makes everyone miserable and can result in other problems, like anemia or vices like cribbing. Regular exercise is helpful in keeping weight under control and improving the circulation to the feet.
Concussion is another cause of navicular separate from over-feeding. The result is the same, however - inflammation of the foot that can result in lameness that may be temporary or permanent. Horses asked to pound along on hard ground for extended periods or asked to jump over and over may develop problems with the tendons and bones in their feet. Heavier horses, like warmbloods, are especially susceptible. These horses are often exceptionally talented at showing and jumping, which makes their susceptibility to lameness a true tragedy.
Other causes include standing too much, as when a horse is confined to a stall and not allowed sufficient time out at exercise. Forcing growth with rich feed, as is commonly done with thoroughbred youngsters destined for the yearling sales, can have detrimental effects. Race horses and show animals are routinely stalled for their protection, given demanding training schedules, and kept on high energy feeds.
Proper trimming and shoeing is important. The natural balance and angles of the foot and leg must be maintained for optimum soundness. If the toes are allowed to get too long and the heels to slope too far forward under the foot, stress is put on the deep tendon that passes over the navicular bone and attaches to the coffin bone, another internal part of the hoof. Heels should also be allowed to spread naturally; contracted or too-narrow heels lead to foot problems.
Lush grass is a danger to all horses and ponies and should be limited. Feed rooms must be securely closed to keep greedy horses out. Exercise programs should be designed with the animal's age and conformation in mind, and riding done over firm but yielding ground. Owners who want their horses to stay sound should learn how to make sure their farrier is doing a good job.
