For the past year or so, we have been putting a meat flavored supplement called Nupro on our dogs' food. We started it because Loki and Heidi were so picky about eating and they liked it. They all like it, but we have found something they like better. My husband hunts and we always have numerous packages of ground venison in the freezer. We fry and crumble it, put it in the frig and top the dogs' food with a tablespoon of it. They tear into their food like there's no tomorrow and I think it is good for them too!
