My Husky teeth were yellow and her breath smelled really bad before using this toothbrush. Now I don't mind her doggy kisses. It was very easy to use and strong enough to withstand her wolf like bites. She seemed to enjoy the flavor as well. I would recommend this to anyone who has trouble brushing their dog's teeth with a regular dog toothbrush and toothpaste. You just put some tooth paste on the brush and let your dog chew on it for 5-6 minutes.
