Patti Tustin, CA 2/5/2011 10:57:02 AM My little 3 lb. Chihuahua has a mouth so small I can barely get my finger in her mouth let alone a toothbrush. I tried, didn't work so now I get her teeth done twice a year by non-anesthesia group at my Vet's office done by a group that does this kind of cleaning. It is all watched over by my Vet. The last time it was done, 81 dogs and several cats took part. We will be going again in a week. Before my Chi, I used to take my greyhound to have hers done. Racetrack Greys usually have bad teeth. Doing anything like this is better than doing nothing about your dog's teeth.
