Charlie's teeth are pearly white since I've been brushing them since a pup. Desta's teeth are horrible for a 3 year old, she has bad breath, and does not enjoy toothbrushing. When I do brush, there is a bit of blood on the toothbrush coming from her upper molar on one side. Having done some research, I've decided to buy a bag of chicken wings next week when I need groceries and test the BARF belief that soft bones from chicken wings, backs and necks do a fabulous job of cleaning teeth and making gums healthy. Fed raw of course. I'm a little squeemish I guess like most people, but have read enough information to give it a try. The other alternative for healthy teeth naturally is raw recreational beef bones. However, I read many more reports about dogs breaking their teeth on hard large beef bones, and almost no reports on dogs choking on raw chicken bones. If raw chicken wings are the pearly teeth miracle that the BARFer's claim, then I'll probably join the local raw feeders coop to buy wings/backs/necks in bulk and give Charlie and Desta a raw chicken breakfast 3 or 4 days a week. We'll see how it goes.
