Hello and thanks for using Petco Pet Education Center, formerly Petcoach! It's hard to say for sure what that is because the picture is fairly blurry. It may be a cyst or even a small abscess (infection) that you are seeing. You can try applying a warm compress to the area and gently cleaning it. However if it gets larger or appears painful or red it's best to have it checked out by your veterinarian.
