I don’t use dental chews for my pets. I brush their teeth once a day with chicken flavored toothpaste, they consider it a treat. (YouTube has excellent how to videos). I have had very good results.
I consider dental chews to be breath fresheners, at best. They do nothing to remove tarter from the back and sides.
I don’t use bones anymore either, due to the risk of broken teeth and GI disturbances I encountered.
