ok this is dum but funny
when i was a young man out working all the time making a living.
sometimes i have a wad of cash in the pocket.
i would wave it in my dogs face (i was probably drunk) and say something like "look at all this money, you dont have any money, thats why all you get to eat is that dry chit, if you did have money you would be eating streak n hamburgers". when i say that last part he would get all worked up and try to get the money in my hand. it was seriously funny

anyway if your curious he had a varied diet.
sometimes i say to him "want me to fry u a egg? he get all excited and jump up n down
