To keep your chews clean give them a scrub with a brush under warm water, using mild, non-toxic detergent, and rinse thoroughly.
Check your dog's chew regularly, make sure it's whole and intact, with no missing pieces. Always replace if the knuckle ends are worn down, or if it becomes too small to chew safely.
These non-edible chews are made with nylon. They are NOT intended for consumption.
