My Tawny (lab) was once called Tubby, but we changed her diet to a Lite dog food, the seniors was too high in protein for her. We also reduced her food by 1/2 cup per day and supplemented with cooked frozen veggies, no sodium, lite biscuits and more exercise. She now wiggles when she walks not waddles, and looks great. She moves alot better, she has had surgery on both knees, cruiate ligaments. 13 and going strong.
