My rabbit has a swollen testicle, weak leg, and is lethargic. What's wrong?

Updated on September 23rd, 2025

Pet's info: Small Animal | Rabbit | Male | unneutered | 4 years and 9 months old

My rabbit has a swollen blue testis and the other one has shrunk. He is lethargic and one of his hind legs (opposite to the swollen testis) has weakened, due to which he has trouble walking. Please, kindly help my rabbit. Please suggest some meds. We don’t have any vets who treat rabbits.

Thanks for reaching out about Snowbell. This is probably not a simple condition so a veterinary visit needs to be scheduled, even if not experts in rabbits. A swollen testicle can be an infection, tumor or other, but due to the nature of rabbit pus, just antibiotics rarely sure this. Recommendation is probably castration. As for the leg, radiographs are probably needed to determine what is going on, fracture/dislocation/spinal problems. Each has different treatments.
Good luck.

Wow, this looks very serious. The left testicle is very swollen. I agree with you. This doesn't add up. He obviously has two testicles in these photos. There is not an undescended testicle. I suggest the vet take him to surgery and castrate him. A hernia into the tunic of the testicle is possible. This is not likely to resolve on it's own. Sorry, we cannot be of any additional help. We would need to examine Snowbell in person. We can only tell so much from photos and your description of events/treatment.

My male rabbit has a swollen, red testicle. What should I do?

Oh goodness. This sounds like he is very painful and possibly even infected. I would highly encourage you to have him examined by your veterinarian. He may be in need of antibiotics and pain medication. Best of luck and I hope he improves soon. Thank you for using Pet Coach.

My rabbit is lethargic and won't wake up when touched. Is he sick?

Thanks for reaching out about Snowball. This is mildly worrisome and a veterinary visit is a good idea to assess. Arthritis or spondylosis can make it difficult to stand quickly. Encephalitozoon cuniculi is a parasitic infestation common in outdoor rabbits and can lead to some neurologic problems. Metabolic disorders can also lead to lethargy. Continue to monitor for water and food intake. Good luck.

My young rabbit has a swollen leg, is limping, and not eating.

I am so sorry to hear about Rambo. I would be concerned he is shivering and not eating due to pain or discomfort. We would be worried about a possible broken bone, an abscess or wound causing swelling, cellulitis, edema, and more. Your bunny needs to go to a vet for an examination. They will palpate his leg and may recommend an x-ray if they feel a broken bone is possible.

My rabbit has black, hard testicles. What's wrong and what to do?

There is a problem with both testicles. The hard and black areas are areas of necrosis (tissue death). This is very serious. Likely due to an infection of some sort. It is very hard for us to recommend treatment for someone to use in a country we are unfamiliar with. I have no idea what products you have available to use. I checked Amazon and it looks like you can get Betadine Ointment 5%. I suggest you apply a thin layer of this ointment twice a day. If it starts to look worse at any time or it does not resolve he needs to see a vet. Be sure his cage is clean and dry at all times. Sitting in urine can cause this type of infection.

Why is my neutered rabbit's genital area swollen after surgery?

Thanks for reaching out about Basil. If there is swelling around the genitals and he is already neutered, a veterinary visit is highly recommended as soon as possible. If he was castrated recently, there is a concern over an abscess or seroma in the scrotum or a hernia. A hernia could be a medical emergency, if intestinal tract has herniated. Monitor appetite, defecation and urination. Good luck.

Why is my mini lop rabbit's tummy swollen, sneezing, and lethargic?

Sneezing is a sign of an upper respiratory infection, it's very common in rabbits. the swollen abdomen could be the beginning of a bloat, which is a dangerous condition as well. you need to take hi to the vet ASAP in order to get him treated, he will need a course of antibiotics.

My rabbit's belly is swollen, but its back is bony. What's wrong?

Hello. I am sorry for such a long wait for an answer, but something is really amiss with your bunnies. To have obvious muscle loss along with an expanding belly indicates some disease process is ongoing. The swelling in the belly can be due to fluid buildup or enlargement of some of the abdominal orgas, called organomegaly. This is really something that requires a hands on exam & possibly some diagnostic tests run as well as a good overview of your husbandry practices. I hope all is well soon & thanks for using Petco Pet Education Center, formerly Petcoach.
