Canadian Brand. K9 Choice Beef Knuckle Bones are a great way to add variety and enrichment to your dog's routine. These edible bones offer a longer, more engaging mealtime that encourages chewing, helping provide a boost of calcium and essential minerals while also delivering a valuable mental workout. Always supervise your dog based on their chewing style, as some may be overly aggressive or try to gulp the bone. Never feed cooked bones, as cooking makes them brittle and prone to splintering, which can cause injury.
