My 6 yr. old Yorkie, Mya, has developed some digestive issues. She has had diarrhea on/off for three weeks and after seeing the vet and trying to reintroduce her current food (Royal Canin Adult Mini) the diarrhea issue returns. Food change needed. She is very, very, finicky so any advice will be welcomed. She does not like canned food. And I think I want to stay away from chicken. Does anyone use Natural Balance Pet Foods or Canidae? Mya only weighs 4 lbs. and needs the tinier bites type of food. Any ideas out there?
