I missed this thread earlier, but it's so timely because I just bought Logan a toothbrush/toothpaste and finger scraper (for me). Although she eats a rawhide bone every night, has normal breath, I noticed that some of her teeth from the canines on towards the back of her mouth, had brown spots. She has a very narrow arch in her mouth, unlike Cody, whose mouth was wide. Logan let me use the scraper- I did it slowly while praising her- but didn't like the toothbrush (she tried to eat it) in her mouth except for the front teeth. I used beef flavored, non flouride toothpaste. I only did it for 5 minutes tonight to get her used to it so she wouldn't run when she sees it. How long did it take you guys to get your dogs adjusted to it? Logan isn't too keen on my playing with her mouth. She uses her paw to move my hand.
