As Thanksgiving approaches, pet owners should be cautious about sharing holiday foods with their furry friends. While small amounts of turkey, mashed potatoes, and gravy may be safe, deep-fried turkey and turkey bones should be avoided. Certain foods like onions, garlic, grapes, raisins, chocolate, and the artificial sweetener Xylitol can be toxic and even deadly to pets. If your pet ingests any of these harmful substances, contact your vet immediately for assistance.
