Horses over the age of 15 are especially prone to arthritis since cartilage begins to wear out faster than it is produced at that age. Older horses also are affected by tendons and ligaments that become more elastic, which can result in tears, joint instability and inflammation. Another factor that contributes to the disease is abnormal growth such as toes that turn out or crooked legs. This type of growth causes cartilage to wear out unevenly. Other at-risk categories include horses that are overworked or generally not physically fit.
Arthritis is treatable and manageable if it is detected early enough.
Because of this, it is important to know the warning signs. Some of the symptoms include mild swelling and heat in a joint, general decreased range of motion, or increased stiffness before warming up. After exercise, horses with arthritis may exhibit either slight lameness or have an obvious limp. Other signs include changes in performance such as a decline or changes in the horse s general attitude. When these signs are present, it is important to have the horse examined by a veterinarian to determine if the horse has developed arthritis.
