It could be an infection, cyst, or a mass. Have your vet take a look at it to determine the exact cause. Your vet can do a needle aspirate to diagnose and then determine the best way to treat. She may need an antibiotic, anti-inflammatory, or it may need to be removed.

    Hi, and thanks for your question. Although a picture of it would help to determine the underlying cause more specifically, generally speaking 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.
