For years, our twelve year old 6 pound dog has required 2 people to do a sub-optimal job of brushing his teeth. The vet would talk to me like I was irresponsible, and finally I asked HIM to show me a way I could brush his teeth alone. He managed, but also had the vet intimidation on his side. That technique only worked a couple of times before the amazingly great evasive maneuvers returned. Also valuing my relationship with my pet, I did not want to hurt him. I had starting as you are supposed to, when he was a baby, allowing him to lick toothpaste off my finger. He just never accepted the brush, of any kind. He has lost teeth, as his breed is prone to dental problems. I am happy to say he is likely this new "brush-less" method, which I stumbled upon because I like Biotene products for myself. Now, I just have to hope the next dental exam will show we are good in that department!
