Burger the dachshund comes to the V.E.C. with a highly sensitive and pained back. It’s up to Dr. Debbie James to diagnose the problem as soon as possible and get Burger into surgery to prevent paralysis in his hind legs. Then, Dr. James receives a Bengal cat named Simba, and something has struck a nerve with his ability to walk. Later, when young Saint Bernard puppy Harley’s legs begin to fail, Dr. James takes her under the knife to repair her spine and get her back on her paws.
