It is important to select the appropriate chew type, size, and formulation based on your dog's age, breed, chewing style and weight. The pressure exerted by a dog's jaw is considerable, and when directed straight down can put tremendous stress on their teeth. It is recommended that non-edible chews be large enough to encourage chewing from the side rather than the top and bottom.
If your dog is between sizes, choose the larger-size chew item. If you have more than one dog in your household, select chews appropriate for the largest, strongest chewer. If your dog is an especially strong chewer, a larger chew may provide more of a challenge.
