The most common cause of hind leg lameness in dogs is a cruciate ligament injury or degeneration. When an injury occurs it can be painful and also predispose the dog to other conditions. Dr Glenn and Bec discuss the cruciate ligament, why injuries occur, how to prevent an injury, the different treatment and management options. Dr Glenn sees a couple of cruciate ligament cases each week, indicating how common it is and why dog owners need to be aware of this potential injury.
