UPDATE:
The vet said that we'll try the antibiotics for one-two more weeks since it cleared it up last time. She thinks maybe he wasn't on them long enough to completely get rid of it. She really doesn't want to have to put Marty through the biopsy and auto-immune testing so she's trying to be very thorough before taking that step.
I hate the waiting, but if it will spare Marty pain, then I'll wait another two weeks... |
