I know we desparately need to get two of our dog's teeth cleaned. At the vet yesterday, we made an appt. for our little Lhaso (he's 5) and in good health, so I'm not worried about him. But my cav, Sasha has had a couple surgeries - one to permanently tie back part of larynx, and I'm worried about a dental cleaning (i.e. anesthesia)again. Any suggestions on my worries?
