Cinnamon barely ate the first month. I started cooking chicken, vegetable, and oatmeal. He finally started to eat a bit more but no big deal. Two days ago someone gave me a small sample of "Natural Balance" in a beef sausage. He really liked this but it's not meant as a diet. Today I found "Royal Canin" canned puppy food. I mixed a little of the sausage crumbled up, the Royal Canine Yorkshire #29, and the canned puppy food. WOW!!! He ate the entire bowl and wanted more. I am thrilled.
Maybe you can give this a try. Good luck.
