It is important to select the appropriate chew toy type, size, and formulation based on your dog's age, breed, chewing style, and weight. The pressure exerted by a strong chewer's jaw is considerable, and when directed straight down can put tremendous (as much as 450 psi) stress on the dog's teeth. It is therefore recommended that nonedible chew toys be large enough to encourage chewing from the side rather than the top and bottom. If you have more than one dog in your household, select chew toys that are appropriate for your largest, strongest chewer. See our Chew Style Guide for more details.
