Review on Japanese-Made MIND UP Toothbrush for Dogs: Kenko Care, Easy to Use! by Mayur Kreps

Finally a toothbrush that fits in my 4 lb Chihuahua's mouth! Pro groomer tip: If your dog hates brushing his teeth like I do, wait until he's asleep. Do not attempt this if your dog is hyperactive and running around. Don't chase them with your toothbrush and don't turn them into a game! That will make it much more difficult. I wait for my chihuahua to fall asleep and bring him a toothbrush and just brush his teeth from the outside, keep his mouth closed and lift his lip (try not to get near the tongue unless he's behaving really good). But be careful if your dog is easily startled or bites. I always speak to him in a high voice and comfort him at the same time. It doesn't matter if all the teeth don't come through right away. It is better to whiten your dog so that he does not have a bad experience. Dampening your toothbrush before applying toothpaste is easier on your gums. Be careful with your gums because they can bleed just like ours!
