According to Kilgore Small Animal Hospital, intervertebral disc disease, also referred to as slipped discs, is a common condition in dogs that causes weakness of the hind legs and pain and stiffness. Slipped discs are more common in dogs with shorter legs and longer backs. If discs slip suddenly, it is referred to as acute disease.
