The term " slipped" is really an incorrect statement. Disc's can herniate or bulge. If your dog has a disc problem, getting them to their Vet is urgent. Symptoms such as dragging leg, refusal to drink or eat, accidents in the house. Once the Vet has evaluated the dog and it is determined that surgery is not essential, then chiropractic adjustments, exercises and acupuncture are what is needed. The sooner all this begins the quicker will be the recovery.
