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!

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. Based on your description, it appears that this could be a skin infection / irritation. Without pictures and without examining Zoey, it is difficult to say for sure. The large swellings under the armpits could be enlarged lymph nodes due to the bacterial skin infection. I would recommend having a veterinarian take a look at this so that the most appropriate diagnostic and treatment recommendations can be made. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.
