My dog has swollen armpit lumps and a genital wart. Is it serious?

Updated On September 23rd, 2025

Pet's info: Dog | Dachshund | Female | unspayed | 11 months and 22 days old

A lump appeared on both sides near my dog's armpit, possibly showing a swelling in the lymph nodes, was given antibiotic, but remained swollen, and I also noticed something like a small wart on the outside of the genitalia. What can it be? Help me please!

Thanks for using Petco Pet Education Center, formerly Petcoach! These could be benign or malignant growths. There is no way of knowing what it is just based on its appearance. This is often differentiated by a test called a fine needle aspirate (FNA) which is a pain free, inexpensive and easy procedure which in most cases will help reach a diagnosis. Sometimes a biopsy is needed for a definitive diagnosis. I recommend that you have her evaluated by your veterinarian for further assessment and treatment. I am really hoping for something benign. Good luck and have a good day!
