Nothing could be more iconic than a dog with a bone. However, both raw and cooked bones are a hazard to canines. Avoid the four Bs: Baked, Broiled, Barbecued, or Boiled bones have a tendency to splinter and endanger your dog’s digestive system. While good for nutrition, small pieces of raw bones also tend to disrupt the digestive system. Additionally, many dog breeds have tooth and jaw structures not suitable for chewing bones. To get the collagen and other essential vitamins your dog needs, consider feeding them unflavored gelatin and vitamin supplements.
