Aquatic therapy for dogs is a form of rehabilitation and athletic conditioning. In both cases, canine aquatic therapy prevents injury, lessens pain, strengthens muscles, and restores or enhances mobility. Dogs do not have to live near water or like to swim to undergo aquatic therapy, which occurs indoors in a shallow tank. Aquatic therapy for dogs is also known as canine hydrotherapy, canine aqua training and canine underwater training.
