Canadian Brand. K9 Choice Dino Bones are a whole beef leg bone that helps support your dog's dental health by naturally cleaning teeth as they chew. If you don't brush your dog's teeth, chewing bones can help reduce tartar buildup, which may contribute to bad breath, cavities, gingivitis, and costly dental procedures. Chewing for just 1015 minutes can also stimulate saliva and digestive enzymes. Always supervise your dog based on their chewing style, remove small worn pieces, and never feed cooked bones as they can splinter and cause injury.
