Dog licking small, bald, irritated spot on arm. How to stop it?

Updated On September 23rd, 2025

Pet's info: Dog | German Shepherd | Male | neutered | 100 lbs

My dog has this small circular wound on his arm. At first it was mostly covered by hair, but now all the hair in that area is gone. He keeps licking the wound making it irritated and tender. I have no idea whether it is a bug bite, fleas or ticks, or just a scrape.

It is very difficult, or nearly impossible, to say what the initial cause of that wound is on Clyde's arm. However, what he is now doing is contributing to its inability to heal properly. The licking is happening because the area hurts, but the licking creates a more profound wound. This in turn creates more pain, therefore more licking, and on and on the wheel turns. As a result, we need to stop the licking. You will need to get a collar for Clyde to wear. You can buy one commercially or make on at home. The area should also be clipped and cleaned with an antiseptic, and something should be applied to the area daily to help with itching. A systemic antibiotic is sometimes needed in these instances as well, which would require a visit to the vet. Hope this helps!
