My dogs are junk food puppies, when I let them be. I give them the option to try any fruits or veggies I'm eating at the time, but they aren't too crazy about them. My Pit Ginger will take a cheese burger and leave the tomatos (just like her mommy). Her eyes and pupils get huge when she sees that burger getting closer to her mouth. We call that her "cheeseburger eyes". She's not quite sure what to think about olives when she first gets them in her mouth. She seems to think anything I'm eating she should at least try, then drop on the floor if she doesn't like it
