I'm aware that there a few things dogs should never be given, especially chocolate and onion. My vet has said that I can give Bentley (7 months) baby carrots, broccoli, green beans, to name a few. I have a bag of trail mix with dried banana slices that I don't care for. I was about to toss them out but wondered if that would be OK for him for a snack or treat. I have no doubt that he'd eat it because he'll eat anything that he perceives as human food.
As for chocolate, we make sure we keep that away from him, but a friend's beloved pet, a beagle I believe, consumed an entire bag of Snickers fun-size bars while they left her alone in the house. Scared them to death, but she had no reaction.
