Haley I am so sorry about Max . I know how you feel because of what has been going on with Babette. This AM I called a rabbit vet recommended by the Wisconsin House rabbit society ..his name is Barney Smith and he is out of the same office in Verona where I took Beau.I talked to him once before because I was told that he will take calls from people who do not have good vets in their area. I told him everything about Babettes problem.....this is what he said 1) If she responded to the Baytril it is probably bacterial (vet I saw Sat said it was probably viral pneumonia) 2. She should be on the meds longer than a week (I got another weeks worth by saying I may need it for another bunny so Angela you were on top of things)). babette is actually better. I have to listen with a stethescope to hear the rasp in her lungs. Dr. Smith said that if it doesn't resolve soon I should get x-rays and that would also tell whether it was cardiac related. I asked him if he would agree to do a phone consultation with another vet and he said he would. Haley...just make sure that you have a good vet..I don't know where you live but I sure both Max and babette get over this. Did Max get this after his teeth surgery??
