Canine Mobility has its roots in helping one dog overcome his knuckling problem and learn to walk normally again. The unique design of the AKD differs from other available products in that it brings the affected leg forward while simultaneously lifting the toes, effectively reducing or eliminating knuckling. In addition, tension from the shock cord as the dog walks promotes strengthening of atrophied or weakened hind leg muscles. The device is effective, comfortable, easy to use and has a proven track record of promoting canine rehabilitation. Please read our terms and conditions.
