Great-Tasting, gluten-free formula made from natural ingredients with no plastic, no sugarcoated or salt and no artificial color. Edible and highly digestible.The pressure put in by a dogÕs jaw is significant, when directed directly down can put tremendous anxiety on the teeth. It is advised that non-edible chews be huge enough to motivate chewing from the side instead of the top and bottom. If your pet is between sizes, pick the larger size. If you have more than one pet in your home, select chews suitable for the biggest, greatest chewer. If your pet is an especially strong chewer, a larger chew might provide more of a difficulty. Bear in mind to supervise the use of all chews and toys!
