My dog's recurring lump below her rib changed. Is it life-threatening?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed | Female | unspayed | 7 years and 4 months old | 35 lbs

I have a 7 year old beagle, she's had a lump appear and disappear in the same spot just below her rib throughout a few years, she's probably had it for the 5th time now. But the first few lumps were movable, soft feeling. this time the lumps is bigger, hard and more lumpy and Im really concerned! Do you have an idea of what it could be? And is it lifethreatning? I dont want to lose my baby girl!

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Pupsie! The growth is very large and I worry about the location. Since she isn't spayed I worry that the mass is associated with a mammary gland. Mammary gland masses can be cancerous or benign. The growth could also be a lipoma (fatty deposit) or a cyst. I highly recommend getting her in to your Vet to have it evaluated. Your Vet can discuss whether aspirating it is worth while or you should just schedule to have to removed and biopsied. I wish you and Pupsie the very best!
