Even before you get a vet appointment – and please please get a vet appointment ASAP – go to a petstore and look for a dog/cat dewormer with the ingredient fenbendazole, or go to a feedstore. Feedstores sell it in large tubes for horses. If you get it from a pet store if will probably be in a powder form and you’ll need a fine scale to weigh the correct dose. The tubes that the feedstores sell also require a fine scale to measure the dose. Like LBJ10 said – it won’t hurt to treat for EC if it is not EC. But if it is EC and you don’t treat it for EC, lots of irreversible damage can be done. There is no definitive test to say it is EC causing the symptoms. Most rabbits are exposed to EC and will test positive. They only way to know for sure – is with a brain tissue biopsie from a dear rabbit. Obviously not your preferred choice. It could be an ear infection like Tobyluv said, and not everyone who pears down the rabbits ear will see it. If it is middle or inner ear – you won’t see if by looking in the ear. Middle/inner are what could cause these symptoms. So ideally – you want your bunny to be on 28 days of Fenbendazole (Panacur), 28 days of baytril, and 28 days of Metacam is also a good idea – since inflammation from EC causes a lot f damage. Metacam is an NSAID that helps with inflammation.
