I am so bummed that I bought the 50 pound bag of food when I got him, the food they were feeding him. It isn't horrible, it is grain free. I looked yesterday and it is 1.10% calcium and .90% phosphorus. Is that bad? It is called Holistics. I also don't know if I am feeding him too much. I think I am. His stools after eating are solid, but he has 1-2 a day that are not totally solid. He is pooping 4-5 times a day and I know that is too much. I am prepared to change, I think to the Earthborn (maybe a shelter will take an opened bag of food?). I feed him 2 cups 2 times a day.
