Thanks guys! Lowers came in great. Actually, she lost them both before the adult teeth peeked through the skin, so there was a short period there where the lower canines were completely absent and she looked really goofy. Anyway, this is part of the reason the uppers are concerning me - they really are showing NO inclination of going anywhere!
We have an appointment with our vet in 4 weeks. She is going on holidays as of today, and we won't let anyone else do it. Also, the pup is on Prednisone for "Puppy Strangles" and we have begun the taper but the vet really wants to see her down to 2.5mg Prednisone every OTHER day before she'll do even a minor surgery. And she will still put her on oral antibiotics as a precaution. So we're balancing doing it sooner with waiting an appropriate amount of time with respect to the Prednisone.
Bad timing for everything. LOL
(And again, while she is a show/performance puppy, she is NOT a breeding dog.
