As our cocker got older, she developed three fatty cysts. (I can't remember the scientific name the vet gave them.) One of these cysts appeared on her chest area. It was firm and didn't seem to be connected to anything. Our vet told us that it was nothing to be concerned about.

Good luck and keep us informed of what happens! My fur crew and I will keep our fingers, fins, tails, and paws crossed for ya!
