This is a pustule probably from a buried suture knot. The suture is absorbable but it takes several months to dissolve and sometimes the knot can cause irritation and a small infected pustule. I recommend taking Patti to your veterinarian and they can feel if there is suture left in the incision. It can be removed now that the incision is healed. Generally when the pustule is opened the knot is exposed and can be cut off and removed with suture scissors. Then the skin will be cleaned and it should heal up quickly once the knot is gone. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Patti Mayonnaise.
