It's important to select the proper size & type of chew for your dog's age, weight & chewing strength. Non-edible chews should be large enough to encourage chewing from the side rather than top & bottom. If you have more than one dog in your household, select chews appropriate for the largest, strongest chewer. Always supervise the use of all chews & toys. Products not intended to be eaten or ingested. If you think your dog swallowed a piece, take the product away and contract your veterinarian. Inspect before giving to your to dog to make sure it's whole and intact. Check frequently & replace if worn or damaged or if it becomes too small to chew safely. Hand wash with warm soap water & rinse thoroughly.
