Oh that is too funny!
"Another trick a friend of mine used was while his dish is on the side pretend your trying some and make a big "yum yum" show of it, then put his bowl down. Leave it while he looks or sniffs then pick it back up and do the "yum, yum" show again. Repeat it 3-4 times each feed. It worked for her within a week. My friend had many problems with her boys, Olde English Sheepdogs, and got a trainer in to help. This was just one trick that worked"
But it works with children also!
