Four Paws has a nice minty toothpaste which I use daily to brush Bud's teeth.
I also use Petzlife twice a week to keep them tartar free.

It works wonders.
I also give him a breath cookie after brushing that has parsley and other
natural ingrediants for his breath. He has never had bad breath to date.
I get them at the pet store.
