Tubby and Peanut have only gotten dry food their entire lives. I didn't want to start them on the canned stuff because when I first got them there was no way I could afford to buy canned. Both have teeth that are in great shape except Peanut somehow "lost" one of her "fangs" and Tubby has horrenously bad breath which means he needs to have them cleaned, but they are good strong teeth for a 14 and 16 year old.
