Marty, 13 year old, has been on a diet for four months along with insulin shots twice a day and has not been loosing weight. His glucose is steadily coming down and the vet is happy with his numbers. We have decreased his food (Purina Pro-Plan DM) to 1/4 cup twice a day but still has not lost weight. In fact he has gained a pound over the last three weeks and acts like I am starving him. He is 20 pounds. Any suggestions?
