What are these black, pus-filled spots on my dog's lower back?

Updated on September 23, 2025

Pet's info: Dog | Labrador Retriever | Female | spayed | 6 years and 10 months old | 65 lbs

I have a 6 year old yellow Labrador Retriever. In the last 5 days, I notes 2 or 3 dime size black scans on her lower back by her tail. These look like puss has come out of them. I am wondering if they are hot spots and if so, what the best remedy is for this. I will upload the pics I took of them.

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Bailey. If there is pus, that means it is infected. These don't look like hot spots in the pictures. I'd have her seen by a vet. The vet can diagnose what is causing these, and can treat her. Best of luck.
