As for too much protein? I really believe that complete proteins should be the main source of energy/kcal in their diet, not carbohydrates, and a large portion of complete protein at that. As incomplete proteins from vegetables and grains produce large amounts of waste that both the liver and kidneys have to deal with. Which in turn, adds additional stresses on both organs , which are already an issue in the Yorkie breed.

That is why I always push complete proteins, as they are easier on the body as compared to incomplete proteins.

Another point of contention with me is the use of "crude protein". Crude protein represents all forms of protein whether it is digestible by our pups or not. So the amount of protein that is in the bag might not actually get into the pup!

......and there it is , I think that I have answered both questions you asked. If you have more, I am still here studying,,,,LOL
