Dr. Claude Lessard is a hospital veterinarian whose own pit bull, Opal, is in need of urgent care.

Tasi is out of control and aggressive toward everything. She's also in danger of being put down unless Cesar can help her owners to rehabilitate her. Next, he drops in on Ebbie Lou, a miniature schnauzer that's about to be banished from doggy daycare because of her disruptive, exited energy. Can Cesar calm this canine and get her a reprieve?
