We are trying to be good about it, we have a brushday every week, but some weeks it just doesnt happen, I use the three sided brushes, I like them because it cuts down on the time you have to dig around in there, and they are pretty good with it. And I think it works because the two older dogs, well not old but no puppies, about 5 years old, both of them has teeth as a two year old says the vet. Never had to have a vet clean them either. So I am a believer in it, even though I could be better at not skipping a week here and there.
