Dogs do very well on beans and rice. Many dogs are eating slices of coconut, banana, orange, avocado, apple. The more a dog bonds with his adopter, the stronger his urge to eat what his adopter eats.

Ice Wolf is right, the Web is full of references to people feeing fruit to pets with no ill effects. But you know how it goes: "If some is good, then more is better."

This thread reminded me of how my brother-in-law used to toss green grapes one at a time to his Weimaraner, who gobbled them up eagerly. Then B-I-L would throw a green olive.

Bastard.
