Ummm...that is all the advice you got for that money? My first suggestion is to find a real rabbit vet. I am not here to flame anyone...vets in particular....but those that have never dealt with ear issues in a rabbit don't really understand the forces at work. I think
www.rabbit.org may still have a listing of suggested vets.
I am not a big fan of Baytril in any situation. And there is a possibility, and we run into this a lot, that if it is a bacterial infection that the pathogen may be resistant to Baytril. I rarely use Baytril now due to resistant bacteria. And the not eating and pooping not related? With the pain and stress of head tilt....I think it's related. The pain and discomfort are quite high and we do see their appetite depressed. With ear infections, they are very tough to treat, they are long term treatment and require aggressive attacks from multiple fronts. Unless it is a very puny infection, which I doubt considering the sudden onset and degree of tilt, Baytril just ain't gonna do it. Some good pain meds will do wonders for this rabbit I'm sure.
As others have mentioned, hydration is essential. Sub-q is best but orally by Pedialtye is better than nothing. And if she will eat greens....dandelion greens are always around here for sick rabbits....they also help with hydration. Offer any bunny safe food in a buffet.
Keep in mind that I am not a vet, but I would really like to see this bunny on much more aggressive antibiotics and pain meds. Ear infections can penetrate the ear drum and cause deafness and can also invade the brain.
It might not hurt to treat for EC after the tilt clears up...dont' want to do too much at once. The most favored treatment is Fenbendazole (Panacur). It is the latest and greatest of the "bendazoles". It has to be administered every day and we have done so up to 60 consecutive days. However, despite the "success" stories you see all over the internet, truth is that this drug is not that effective. Has to do with penetrating a blood/brain barrier (odd that the parasite has no problems doing it). Our experience in treating with Fenbendazole has been limited in success and disappointing to say the least. We have even used a "cocktail" of different drugs with not so muchsuccess. I am in the process of working with a drug called Marquis that appears, on paper at least, to possibly be more effective. Amazing how one of the simplest organisms on earth can be such a pain to deal with. EC is quite a challenge.
But for now, until we get a handle on this...I am still thinking vestibular infection and I think further diagnosis is in order. I suggest a much more detailed look in those ears to see what is going on.
Feel free to PM me if you need more detailed info. I am somewhat limited in this since I am not a licensed vet but I will do what I can to guide you in the right direction.
