I have this large dog who is four years old, just this morning this large raised bump appeared on his front leg near his elbow, it is a large red raised circle on the outside and in the middle it’s a white ish yellow (like puss) but when squeezed nothing comes out. I can’t find anything like it in the internet and I’m starting to get worried about it xx
No expert but it sounds a bit like a sebaceous cyst. Probably best not to squeeze it.It will burst itself if ready and you might infect it if you keep trying. I believe they tend to go without treatment but I would go to the vets if not after a few days. Keep it clean in the meantime.
