Do you know what this is?

The first right answer gets the 10 points.





I found a large knot on my new rescue dog's back last night. It's about the size of a quarter and rock hard. Doesn't move. Has no discoloration on the skin but one very small red spot near the center. What is it?





*** I took him to the vet first thing this morning so I found out what it was but didn't have a clue beforehand! Just curious to see the knowledge going around here on YA since my vet said that exact description over the phone told her exactly what it was.





*** Don't just answer it, tell what can cause it and what to do about it.

Sounds like a sebaceous cyst but thats just a guess. If it is, it's kind of like acne in people. It's an issue with that gland in the skin. Most of them that I have seen, we just pop. Gross puss stuff. Not fun. But thats just my guess...
Reply:To really get a good idea, I would need to see a picture. Even then I might need to touch and feel it, or stick a needle in it.





My best guess would be sebaceous cyst, a clogged sebum gland, kind of a giant pimple. If that's what it is, then drain it or remove it surgically.
