Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Gin Gin. Oh that looks bad, and I suspect it's infected. I see pus in the picture, and it is quite open. It could be a tumor but it would be rare because she was spayed early. The best thing to do is take her into a vet now to get this treated. I hope this helps!
