 Does Thanksgiving favorite make your dog sick? Stuffing. Yup, it contains onions and garlic, which can be super toxic to your furry friend. Plain pumpkin. Nope, this is a tasty nutritious treat. Go for it. Pumpkin pie filling? Yes. This often includes xylitol, which can be deadly to them. Turkey. Depends. If it's on the bone or has skin on it, it's a no-no. If it's plain, they can enjoy it. Mashed potatoes and ham? Yes, these rich foods can cause pancreatitis or other digestive problems. Plain potatoes or plain sweet potatoes? Nope, these are fine. Alcohol. Do you really have to ask? Don't let your dog be part of the surge and emergency vet visits this Thanksgiving.
