Designed to clean your dogs teeth as they chew and provide them with essential vitamins and minerals for a balanced diet. Bristles and grooves wrap around teeth for greater surface area. Chewy texture promotes teeth sinking into the treat all the way to the gum line for a more thorough cleaning. Knuckle ends help the dogs grip the treat with their paws for easier chewing. Not intended for dogs less than 5 lbs. or less than six months of age. Available: 12 oz., 27 oz., 36 oz.
