Most people enjoy spoiling their dogs and giving them treats, including giving them "people food," as it is called. There is nothing wrong with this if you remember dogs are not small humans. Canine bodies are different from human bodies, some human foods can sicken dogs and even kill them. Check with your dog's veterinarian if you are in doubt. Several types of fruits and vegetables are harmful to dogs and should never be eaten. Additionally, any food that causes your dog to have diarrhea should be off limits.
