I have to give each dog a treat in their own separate kennel. If there is any left when the dogs are let out of their kennels then I just have to lock the kennel shut so the others don't steal what isn't theirs. All 3 of my dogs prefer the other dog's treat regardless of the fact that all 3 are identical items. For some reason they think somebody else's treat is better. My female beagle is the absolute worst one of the bunch though.
