Dharma is five months now and I've been brushing her teeth since she was three months. My vet told me to do so; that way she started to get used to it while she still a baby. Yorkies's teeth tent to decay easier and faster then any other bredeer. I do brush her teeth every day. I do it after she've play a lot and become tired. Night time since to work better for us. Good Luck
