Julie, no, I think it was a time frame restriction, and the vet felt that any TBD would require doxy anyway, so we just treated accordingly, knowing that using the doxy wasn't harmful to the dog. However, after a month of doxy, we saw no improvement, so assumed that TBD was not at fault.
Honestly, not knowing exactly what to press the vet for kind of left me vulnerable to what he believed, rather than doing what needed doing. After many hundreds of dollars on fungal tests, I'm told that they aren't all that accurate anyway. Seriously?
So, working with the money available we tried to test for most likely and treat for TBD regardless of testing. Also, tick illnesses are kind of rare here, so it wasn't high on the list. My guess was blasto, which is also almost unheard of, but the specialist thought crypto more likely. I even suggested distemper, but the symptoms didn't follow closely enough, and with vaccines, almost unheard of also.
$2000 later I still don't know what it is or isn't, but the recent recovery is promising, my only long term concern being her eye.
Overall, I felt that the vet should have assigned more seriousness to the issue, we lost a lot of time with hmms and haws...some tests took 10 days to get back, etc
Just as this was setting in, she was supposed to go off to Martha McHardy for training, now I'm ot sure she'll ever get to chase woolies
But, we were close to calling it done, and she started to come around, so even if she loses the eye, she's still here and happy again
