Updated On September 23rd, 2025

Pet's info: Small Animal | Rabbit | Female | unspayed | 2 years and 11 months old

My rabbit has a huge lump under her chin and all her neck I'm so worried for her. The fur is all falling off around the lump and flaking. And she is not as active as she used to be she is always lying around in the garden and eating tiny amounts of food as she has overgrown teeth. Please help.

I am very sorry to hear about Stanley. It sounds like she definitely needs to visit the veterinarian. In a rabbit with a swelling like this we worry very much about an abscess, or pocket of infection under the skin. This can be especially common in rabbits with dental issues, such as overgrown teeth (which it sounds like your bunny is suffering from). She needs to see the vet not only to address the abscess (which may require the vet to open and drain and then prescribe antibiotics) but also to address the teeth which may require trimming to allow her to eat normally. If untreated the condition can progress and lead to a painful death as the rabbit eventually becomes unable to eat.

    Thank you for including the picture. That could possibly be an abscess or a tumor. It looks a little low to be a tooth root abscess, but it May be the angle of the picture. I would highly encourage you to have him evaluated by your veterinarian as soon as possible. A needle aspirate may be done to help determine the diagnosis. From there antibiotics, and or mass removal may be discussed. Best of luck and I hope he improves soon. Thank you for using Pet Coach.

My 8 year old rabbit has a lump under his jaw. What can this be? It just randomly appeared. He's still eating right.

My rabbit has had a few problems and from this info I need to know if this could be contagious or if I can breed him with my doe. Maybe you can even tell me what’s wrong. It started 2 weeks ago Thumper started getting a wet chin. Later one day he got
Thanks for reaching out about Thumper and including photos. By the description and swelling on the right side of the face, a dental abscess is highly suspicious. The dental disease is making it difficult for Thumper to eat, therefore loosing weight. A veterinary visit is recommended, the sooner the better. Rarely do antibiotics solve this problem, might requiring some surgery or tooth extraction. Good luck.

Hi I have a rabbit (6 years old) and a few weeks ago I noticed that he had a ball in the right thigh (thought it was an abscess and that in a few days it would decrease and return to normal) However it remains the same but now there's a wound in that
Poor Shu! I can see that the growth is relatively large and inflamed. It also appears to have a bit of dead tissue in the center. This is likely to be fairly painful, so Shu should be seen by a vet to receive pain medication and a thorough cleaning of the area which may require mild sedation. There are certain viruses that predispose rabbits to developing masses, and while there is no cure for the virus itself, the mass can be removed to improve quality of life. If you have any other rabbits, I recommend separating them from Shu as the virus can be contagious. I hope this helps and that all is well!

My rabbit has a lump on Its right side ? Not actually sure if the rabbit is a girl or boy we just assumed it was a boy. He has a soft lump and jumps when you touch it . He’s been acting normal running around and eating as normal so not sure what’s wr
This lump could be a cyst, an abscess, a benign tumor, or a malignant tumor. Any suspicious lumps should be examined by the vet. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of its cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. Once the cause of the lump is diagnosed, the vet can discuss treatment options if needed. I would give Harry's vet a call in the morning to make him an appointment. Best of luck.

What can I do for my rabbits lump
Keep the area clean and dry. Consider an exam with your veterinarian or a vet experienced in treating rabbits to diagnose and treat infection or injury. A fine needle aspirate can be done in the clinic to collect samples for pathology to diagnose a malignancy.

My rabbit has overgrown teeth and can't eat well What should I do?
Poor Stanley ! There is nothing you can do at home to help his overgrown teeth. You should have him checked over at the Vets where his teeth will also be trimmed. His diet will probably need to be revised, to make sure he eats enough fibre and hay and little treats or rich in carbohydrates pellets.

My rabbit has a tumour like lump near her anus, her insurance doesn't start for another 12 days it has not grown in size since yesterday and she is eating / pooing fine just wondered on the urgency of getting her to the vet.
Lumps and bump can certainly be scary, especially since we usually don't have any idea what they are. As long as it is not effective Poppy's ability to urinate and defecate, and as long as she is eating / drinking / having a good energy level, there is not absolute rush to have her seen. However, I would definitely get her to the vet to have that area examined as soon as it is financially feasible to do so. It is in an area of the body where if the size increases, the mass could certain become problematic. It is best to deal with it sooner than later. If the area starts to grown in size by even 10%, I would not wait until the insurance kicks in and just get her somewhere to be examined. While I realize this isn't ideal, rabbits are very sensitive to changes in their health and have the ability to crash quickly if things are not hastily dealt with. If you have any others concerns, don't hesitate to contact me. Hope this helps!

hi i have noticed a lump in my rabbits belly further to the back not sure what it is also i notice he chews on the cage too. when i take him out he is not too active he just basically stays in one place also his nails appear to be curving. any sugges
This kind of lump/growth needs to be ideally assessed by your veterinarian to have a definitive and specific answer. Usually there are two ways your vet can do that a part from examining it directly during physical examination. A biopsy can be taken under local or general anesthetic, otherwise a smaller sample through a fine needle can be aspirated (this technique is called FNA= fine needle aspiration). Differentials include skin cysts, infections, benign or more sinister type of tumors. Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

My guinea pig has a lump on her face and it’s hard and it’s also close by her jaw it doesn’t seem to bother her because she is eating normally and drinking normally can you please help
I can see that Lilo has a swelling over her jaw, which may be a sign of a tooth root abscess. This can result in discomfort and difficulty eating. I recommend having this evaluated by a vet as soon as possible, as she may need to have teeth extracted or dental x-rays. In rare cases, this can also be caused by a growth on the bone, either due to a tumor or inappropriate nutrition. In the meantime, you should ensure that Lilo has a well balanced diet and keep an eye on her for issues eating, weight loss, or any nasal discharge. I hope all is well and thank you for using Boop by Petco!

There is something beneath my dwarf rabbit's mouth. It looks infected. What could it be?
It's hard to tell from photo, but that looks like some superficial skin hanging down from the surface of the jawline. If this is the case, there is likely an open wound. The skin that is hanging either needs to be trimmed off or it needs to be sutured back into place. This should be done by a professional to ensure the best outcome, and to allow you to obtain oral antibiotics and pain medication. When rabbits aren't feeling well, they can often stop eating which is a recipe for disaster unfortunately. I would have Totoro checked out some time soon to be examined.
