I use Petrodex poultry flavor toothpaste (they have beef too)...at first, they hated brushing, but after regular brushing, they seem to trolerate it. I use those little finger brushes & the tiny cat toothbrushes for the back teeth. Just lift up their lips on both sides to brush the front & lift up one side of the lip to brush the back & insides. Top & bottom...hope that helps. It would be nice if someone made a video of it.
