Hi I have a quick question my 2 year old baby boy has not been eating his dry food for a day and a half (its the one he has since birth) but he has been eating the 2 chicken popper treats that I leave for him before I go to work, he is drinking normal, acting like himself and going potty normal. I know if I give him chicken he will eat, it but do dogs grow out of their dry food ???? Thanks ...
