I suggest you find yourself a competent rabbit savvy vet asap, as your current vet appears to not have the foggiest idea as to what he needs to be doing to treat your poor bun. Previously I used a what I call GP vet, but they for the main are all rubbish and my rabbit was completely misdiagnosed, on 4 separate incidents. It was only when the last vet thought it would be kindest to put Roger to sleep, that I knew I had to have a second opinion, and so contacted a rabbit rescue in my area to see who she recommended. She then put me in touch with an amazing rabbit vet, who has a rabbit clinic, everything surgically is all geared up for rabbits, all he does is rabbits, and people travel from all over the country to him, as he has got such a fantastic reputation and so much experience and knowledge. As soon as he saw Roger and made the correct diagnosis and was given the correct medication, Roger started to improve dramatically within 24hrs. Please be aware that all other vets apparently only spend one afternoon out of their 5yrs training on exotic pets, which is the category rabbits come under, and really have little or no real knowledge of rabbits at all. I am currently campaigning with the Royal Veterinary College, for vets to receive more training for rabbits, as they are the 3rd most popular pet, and vets probably see them on a daily basis, but have no idea as to what they are doing. I wrote to the Practise Manager of the vets who wanted to put Roger to sleep, advising her of what was actually wrong with Roger, and what their vet had been contemplating, and to be fair she said me a really lovely letter, a cheque refunding all the monies I had paid them, and assurring me that they would be reviewing their policies for treating rabbits. If they did then brilliant, but to be honest they would never be able to offer me the service and support that Simon does, and I would never use such a Practise again, because their surgical instruments etc all tend to be more geared up for dogs, which is the animal they mostly operate on, but I now know that that poses too much of a risk to rabbits, and so would not use such vets again.
