My guys always get their own burger whenever we go through the drive-thru, actually they always get something from any drive-thru. It's usually a plain hamburger or cheeseburger, sometimes mc nuggets.
If we go to the vets or any partially tramatic event or if they were on their best behavior for an event I make a special trip there just for them.
I allow all my dogs to eat people food so their systems are used to it. Granted I don't give them a lot of people food but they do get some just about every day.
