My dog sitter taught me a trick. When my collie doesn't feel like taking his pills, which I wrap in Sara Lee's White Whole Wheat bread cuz it's nice and doughy, I just give the other dogs a piece of the bread. Romie sees that and then gulps the next piece which contains his pills, because Heaven forbid another dog should get what is rightfully his. So, if you let your 2 year old have a sniff or bite out of his dish perhaps it will make his dinner more desirable to Buford, which is what I used to call my little Bif, as a nickname. Best of luck.
