These foods can cause severe illness or death in dogs. I didn’t know this until I became a student at Animal Behavior College. Some may know this and some may not, but I thought I’d share because I don’t like seeing sick dogs, especially if it can be prevented. Foods to avoid are: Apple seeds, candy and gum — containing sweetener Xylitol, cherry pits, chocolate, garlic (in large amounts), macadamia nuts, mushrooms, onions, onion salt, onion powder, peach pits, plum pits, persimmons, raisins, grapes, walnuts. I hope this helps someone.
