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 and water additives 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.
PS: I like Petrodex 6.2 oz tube, Chewy.com has a good price. The trick is to brush at least once a day. Small breeds tend to have lousy teeth. The daily brushing will make a BIG difference. I don’t bother with chews, powders or any of that gobbledygook, it is the abrasive scrubbing motion that does the work, I even have one of my dogs used to a battery operated toothbrush which provides good brushing motion.
I add a splash of water to their food also, it helps to cleanse, a lot of dogs don’t drink enough water and small breeds are prone to bladder stones if they don’t consume enough.
