Our doggy is a Chauwawa and lost some teeth. Missing top canine teeth from falling off back of chair. Than was spade and before the vet could do that, had to pull 7 more teeth. They figure she is between 9 and 12 years old. We figured she was about 7, because the pound told us, she was a little over a year old. Plus she would have more gray hairs if 9 to 12.. Bink is her name..
