Thanks for your reply. X ray of abdomen showed all clear and normal with the bowel with no masses or anything unusual outside of heavy gas pockets. His stools are well formed and normal size. He eats well and drinks normal amounts. He is just not a food motivated dog. If he is not hungry at the time, even his favorite things wont appeal to him. Very picky but I will try the butter on veggies. He likes butter pretty well. Your thoughts on Candida are something that never occurred to me. Will pursue this avenue for sure. Appreciate your time and info.
