Bunnies need yearly physicals, too

Most of your columns are about dogs and cats, but I am hoping you can shed some light on a problem I have noticed lately with my rabbit. She is about 3 years old and is not spayed. Recently, she has developed a raw rear end and I wonder if it has to do with her not being spayed. The area is red and somewhat swollen. What could it be and what do you suggest that I do? How often should I have a rabbit seen by a vet and is it really necessary? Also, are there any vaccines that I should get for my bunny? I have not had her seen or gotten her any shots before so any advice would be much appreciated.

Veterinarians, myself included, are usually familiar with common rabbit maladies and some veterinarians are more knowledgeable than others when it comes to rabbits. If your local veterinarian is not well versed in the care of rabbits, there are those who specialize in exotic species, including rabbits. The fact that your rabbit is not spayed is not likely the cause of her current problem, although possible. However, spaying a rabbit can have many beneficial effects. Spayed rabbits are known to typically live longer lives with reduced risks of breast or other reproductive-linked cancer or urinary tract infections. Spayed and neutered rabbits are also easier to manage because they are often calmer and less aggressive. They also will have less behavioral issues like urine spraying or marking and mounting. Spaying is typically done at around 5-6 months of age, which is younger than your rabbit.

Is your rabbit indoors or outside in a hutch? That would allow me to have a better sense of possible causes to what you see. Possibilities that come to mind are wet tail caused by urine scalding, fecal matting and something transmitted by various bugs like fleas, mosquitoes and flies called myxomatosis, which is a virus. I would suggest that you do have your rabbit seen by a veterinarian to rule out possibilities. There may likely be a need to clip and clean the area. Keeping it clean and dry is important for the healing to begin. Various medications may also be needed.

As for checkups and vaccines, I would advocate for an annual physical exam, as in other species. There is little need for any vaccines although there has been a recent increase in cases of Rabbit Hemorrhagic Disease Virus nationally and there is a vaccine now available. I always suggest vaccinating based on risk and if your rabbit is solitary with you, there is little need. Good luck.
