I asked my vet this same question and you'd be surprised at the things that they are NOT allowed to eat. Mainly you should stick to apples and carrots. The vet told me no oranges to high in vitamin "C" for dogs, no bananas, or strawberries or anything like that...way too sweet for them, no grapes or onions. Baiscally he said just stick to apples and carrots there are lots of different things out there that may be okay for us but defently not okay for these little guys.
