Carrots and bananas are ok, in moderation..good for treats. Things that are bad, or can kill your dog, are chocolate, especially dark chocolate, because of the theobromine ingredient, onions, human drugs like Aleve (naproxen)grapes and raisins. If I've forgotten anything, someone will add it.
mine love carrots. Rasins and grapes are also bad. I get the baby carrots, and give them almost everynight before bed. They love them, and when they hear the bag, they come running and sit to get one lol
our vet told us that peanuts can be bad for dogs that it can make them have hair loss. and we have a dog that loves peanuts and grapes, we try keep her from eating them but we have small children that like to give food away to the dogs. and for some reason i have a pom that gets really bad gas off of balony and hot dog wennies.
