Sometimes when tissue is cut as in surgery or injured, or was infected as with a cyst, it can be slow to heal back together. If your dog continuously scratches or rubs the area that may prolong the healing as well. I only suggest this because "if" your dog is irritating the area it can complicate their diagnosis. It may be that going back in and debriding a slightly larger area around the original area will allow for healthy skin cells to take over and finally heal like it should have the first time.
