Dog has pink spot under chin, now a new one. Is it an infection?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Large (61lb +) | Female | spayed | 3 years and 5 months old | 65 lbs

On Thursday, I noticed that my dog had a pink spot under her chin where her fur had seemingly been rubbed off. Today (sunday) I found that the initial spot has scanned over but now it seems that a new spot appeared directly above it. Should I be worried? I thought that it was most likely from her rubbing her nose on a rock or something until I saw the new cut today, that’s when I began to have doubts about the seriousness of this issue.

Thanks for using Petco Pet Education Center, formerly Petcoach! This looks like a focal infection. You can try to use chlorhexidine containing pads (such as the Douxo chlorhexidine 3% PS pads) to clean the are twice daily for 7 days. You may find these online or at your local pet store. If there is no improvement or in the meantime this appears to be getting worse, have her evaluated by a veterinarian for further assessment and treatment. Good luck and have a good night!
