Is she getting enough protine? My pup is a rescue and we found out he has some diet issue. We thought he was done growing, then when we got him on better food, he got bigger again. Now he can pull me accross the room with his rope toy!A year in December! Did your pup stop growing at a young age? Mine did.. She is the height of most pits and yet she is super skinny. But maybe her mix is just making her skinny!
