wow that is sad
yeah went to a meetup with a bunch of yorkie owners and many got their dogs teeth cleaned anesthesia free as one girl in our group her uncle is a dentist and felt it was ok to do it this way.
I think if my dog had health problems like ct or heart i would do anesthesia free cleanings as every one raved about how good there dogs were and the person told them if there was a loose tooth etc and to check with vet etc.
I do the dental cleanings with a dentist but i am going to also look at anesthesia free as well after hearing so many good reviews
It is always so sad when we try to do the right thing and something goes wrong
