It looks like a little wart or less likely a skin cyst. These are quite harmless and go away on their own. If it grows, changes colors or starts to bother Wendyl, then you should take her to the vet to get it checked out. They can take it off easily and send it to the lab for positive identification if needed.

    Hi, it is difficult to comment without having him checked over. Some lumps that appear in this area are definitely concerning and need to be checked over as soon as possible. By this I mean during regular daytime hours, but I would not leave him a week without being examined. Hope this makes sense and that the lump is nothing to be worried about.

    Without seeing her in person, I can't say if this is a skin tag or something more serious. Any suspicious lumps should be examined by the vet. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of its cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. Once the cause of the lump is diagnosed, the vet can discuss treatment options if needed. Give her vet a call to make her an appointment. Best of luck.
