You could try some sample packs of the Chicken Soup adult formula to see how he does on it, or even just buy a small bag of it. My 5 yr old Yorkie does ok on the Chicken Soup, but she seems to be able to eat almost anything. The only food I really had any issues with was StrongPoint Naturally Premium. When I tried that food, she started leaving little clumps of black hair all over the house (on the carpet), and it stopped when that food was gone and I moved on to another brand of food. Never had that issue before or since, so it must have been something in that food. A lot of places have sample packs of foods that they can give you to try. Good luck. |
