I found something that seems to work well for Winifred. They are called Mini Dingo Dental Bones. They come in a pack of 7 and they are labeled Day 1 thru Day 7 down the side of the pack. They help that stinky breath, too. They are cheaper at Walgreens than the other places. I tried to brush Winifred's teeth once and three of us couldn't hold her still enough to do it.
