Question
AnswerDear Picky,
I think the following two articles will help:
www.bio.miami.edu/hare/sneezing.html
and especially:
www.bio.miami.edu/hare/culture.html
It's possible that the bacteria causing your bunny's upper respiratory infection are not sensitive to the antibiotics you're using. (What is the name of the medication?) If that's the case, then a culture and sensitivity test will help tremendously.
Also, sneezing can sometimes be caused by dental problems, which you can read more about here:
www.bio.miami.edu/hare/dental.html
If you don't feel your present vet is very experienced with rabbits, you might be able to find a vet who is more familiar with rabbit medicine here:
www.rabbit.org/vets
I hope this helps. Please write back if you have any other questions.
