Has anyone had any experience with their Dane getting a cyst? Dozer has a lump on his side up toward his the top between his ribs and hip. It is not sore to the touch. I can pet him there and feel it and he doesn't even react except to look at me and say don't stop rubbing me. It feels like muscle but not hard muscle kinda like fluid. He has vet appointment on monday and will ask vet but I was wondering about anyones experience. It is about the size of a half dollar. Oh it is under the skin not down in the tissue, at least I hope. It is not deep at any rate.
