Sheba is a 7 year old German Shepard Dog. She was significantly overweight weighing 55kg which was approximately 20kg over her ideal weight. As a result of this she developed a degenerate condition in her right carpal joint (her wrist joint equivalent). The referring veterinary surgeon was proposing a surgery to fuse the joint to stabilise the problem but could not operate with the dog so overweight. This created problems for the general anaesthetic and increased the chances of complications in recovery from the surgery. Sheba was put on a diet and had regular hydrotherapy sessions. She progressed very well and lost 20kg of weight. In addition, the weight loss improved the condition of the carpal joint so significantly that she no longer needs surgery.
