We have a dog with a huge fluffy coat, and we had no idea he had gotten fat because with all that fur you can't really see his body, and we're pretty active with him so it's not like he sits around a lot. When the vet very kindly told us that he had gotten fat, we despaired because obviously there is no way that you can possibly have your pet lose weight. Oh wait, no we just fed him less. I guess we were the ones who had been putting too much food in his bowl! Who would have thought that you could just put less food in the bowl, and the pet would lose weight? Shocking, I know, but somehow our dog became normal weight again within six months.
