My dog's rear skin tag is growing during heat. What should I do?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Female | unspayed | 6 years and 8 months old | 175 lbs

My dog has a skin tag on her rear that has been getting bigger every time that she is in heat. The size is about a little bigger than a golf ball. It feels soft, but feels like there is a mass inside it.

Hello. You are correct, this is a skin tag, but a bit bigger than a tag. At this point, you have a pedunculated mass. About 99% of these are totally benign, but we do recommend removal just because they can continue to grow & become traumatized. Removal is curative. Thanks for using Petco Pet Education Center, formerly Petcoach.
