Why does my dog have a small, movable, painless lump on her skin?

Updated On September 23rd, 2025

Pet's info: Dog | Jack Russell Terrier | Male | neutered | 7 years and 9 months old | 50 lbs

Small lump or bump on dogs and her thigh. It is colorless no openings just raised on my own. It has not changed in size over the last few weeks or month. Doesn’t seem to hurt or price pain. When I touch it it pulls up with the skin so not attached to muscle possibly?

This looks like a benign fatty mass. They are common in older dogs and are not attached to deeper tissues usually. I’m glad you are watching it. The only way to know for sure is to have a needle aspirate and cytology done, which I recommend. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Jack.
