This has three slightly different shaped "greenie" like bones that you give your dog over three days, as they each clean differently.

I did as the instruction, and I didn't notice any difference on the dogs. I think you could get the same results from giving rawhide or a greenie.

My dogs liked the taste and ate the bones. It took them as long as a greenie to chew, which is about 5 to 10 minutes depending. They did manage to bite little pieces off and then ate those pieces as they chewed.

I guess they have a scraping effect, but it is best to just brush their teeth. Perhaps I don't see it since I brush the teeth a lot, so there isn't a lot of buildup. Also, most of these and any other chew doesn't help remove the tartar (yellow hard stuff). I think it probably removes some of the plaque.

The tartar needs to be scraped off with a scaler.

Pros: Dogs like the taste

Cons: You need to use it in order

Much easier then brushing. We give them one every few months to keep their teeth clean

Pros: easier than trying to brush

Cons: sometimes they make a mess w/ them
