I have a chubby puppy (grown dog) and he needs to lose 30 pounds but it is not as if he is lazy or overeats because he is on a strict diet and has been on a special food. He is out every day on the farm running around with every one else and getting his steps in. I think he gets calories transdermally or by photosynthesizing because his caloric intake is so strict; we watch it SO closely and make him come inside and wait when the outside dogs are fed, etc., and he will be inside and home all day, inside with full bowls of food, while we are gone and he will not eat the food, just to eat it because we come home and the bowls will still be full. So I think he is just a Big Boy. But he does need to shed a few pounds. So that is my goal– to get my little Henri-Luc a bit Littler.
