Denyel,
Im glad that you posted this question. I was wondering the same thing. My yorkie is 9 months old and i still need to learn so much. I use Pet Dental toothpaste and i tried to brush her teeth everyday which is not easy cause she tries to brake loose. I was using tearless puppy shampoo, but im getting something better soon, maybe i will try vellus i have heard is very good. I do use detangle spray everytime i brush her hair.
