Yes and no. Plain roasted turkey is part of many commercial dog foods and is not toxic to canines. However, few of us roast a turkey without added butter, spices and stock make with onions and garlic. Here are a few tips for safely serving turkey to your dog: skip the skin which is fatty and any bones which can cause digestive issues; and a small serving (a slice) is enough. Always talk to your vet about adding food scraps into your dog’s diet, especially if your dog has a preexisting health conditions like diabetes. Do not feed "sides" such as stuffing or casseroles that contain other ingredients such as breads, onions, garlic or spices.
