DR Laura, it's hard to answer your question on Annabelle's respiratory problem and the dental surgery. The broken tooth needed to be removed if only to stop any pain it might be causing and to see if there might be an abscess causing the issues. I thought we had solved the problem, then I had to take her to the vet because her nostrils were closed off with gunk, and there was clearly still a problem. I think the air purifiers are helping, since O think it's now an allergy issue, but every other daqy or so, she has her sneezing fits, so . . .
