Why is my rabbit suddenly acting aggressive towards my new puppy?

It doesn't say how old your rabbit is, but if you got her as a baby then she has likely become sexually mature. In female rabbits, this can cause them to become aggressive and not like to be handled. The best and easiest way to solve this problem is to get her spayed. This will remove the hormonal influence on her behavior and help her to settle down. Once she has been spayed you can start working with her and getting her used to being handled and patted again. Keep these sessions short and positive, and use a bit of her favorite food (a little bit of banana is a favorite of my bunnies) to keep it a positive experience.

I am so sorry that this change is happening - it is never easy when one pet starts to be aggressive to the other. I don't know when the last time that you had a wellness exam performed on your rabbits, but I think that would be a good place to start with these two. Sometimes a more dominant animal will "pick on" the other if it isn't feeling well - this is often picked up by the animals in the house long before it is noticed by the humans in the household. Your veterinarian would perform a physical exam, and then could also perform some blood work to evaluate systemic health. Since it looks like your rabbits spend some time outside, they may also evaluate the feces for any evidence of parasites as well that they may pick up. I would also recommend weighing both of the rabbits - it sounds like a lot of the negative interactions occur when food is present, and this may make it hard for your lop to get adequate amounts of food, and weight loss can occur. Additionally, there may be a process going on in the dominant rabbit that is making it need more nutrition and, therefore, is becoming more aggressive about food items. One thing that you may try while waiting to get into the vet is separating the rabbits with a physical barrier that they can still see through - then if they still want to lie next to one another against the barrier they can, but the lop can get away easier if getting picked on. You can feed them near the barrier as well, in case they are social eaters. This may make them feel more comfortable than being completely separated from one another.

Thanks for reaching out about Zoomie. Most likely it is because she is an intact female, and is fighting for territory and dominance. She needs to be spayed to prevent uterine neoplasia anyways, so now would be a good time. If she continues to be aggressive to the dog and cat, something bad is bound to happen, so isolate her for now. Good luck.

It sounds as though you are described territorial behavior. Female rabbits that have been spayed usually don't develop this type of behavior once they get to be several years old. She may be becoming defensive or fearful if she has an illness she is trying to hide and therefore protect herself. Some illnesses to consider in this case are dental diseases, urinary tract diseases or sometimes skin issues. If she has not had a recent (3-4 months or less) veterinary examination, I recommend starting with an examination to ensure there are no health issues involved. Beyond that, you could consider placing her in a new cage or hutch, feeding her directly from your hands (if possible to do safely) and giving more social interaction time outside of the cage.

Sorry you are having this issue. She is most likely being territorial as she is becoming sexually active. Females can get very territorial and aggressive when they reach this stage. My honest recommendation would be to have her spayed - that will diminish any sexual drive and that may help decrease territorial behavior. I suggest you read these articles. They may help you try to correct this behavior. I still recommend spaying her..... http://rabbit.org/faq-aggression/ http://www.wikihow.com/Socialize-Your-Rabbit Hope this helps. Best wishes!

Puppies can sometimes be A LOT for senior dogs and it can take some time for them to get use to one another. If there were any food, treats, toys or special people near by Buddy could have just been acting protective over these. Also, with Buddy being older, if they puppy is always playing, jumping on him, or nipping at him, he may have been just trying to tell the puppy to leave him alone or trying to set some boundaries. Also, if he is arthritic and he knows the puppy jumping on him hurts, he could have reacted to prevent this. I would continue to keep them separate until you know they can be left alone together. I would definitely feed them separately as well. I would be sure you are still spending plenty of alone time with Buddy as he may be feeling frustrated that his home life has changed with the new addition. I would continue to have short but frequent times of them being together. You could also start Buddy on an anti-anxiety chew like composure or composure pro and get him a calming collar like sentry or adaptil. If these don't help, talk to your vet about anti-anxiety medicine like fluoxetine or trazadone. I hope this helps!

Thanks for reaching out about Mr. Magoo. It is unusual for rabbits who are castrated to become aggressive after living together for some time. Environmental stresses can shift hierarchies and start aggressions. Adrenal tumors can produce testosterone and lead to aggression. Not all rabbits get along, forever and they might have to be separated. An examination with a veterinarian with experience in rabbit could probably help you. Good luck.
