Some time back I called about a doe I was interested in. I was told she had some little hard knots in her udder. They can't be seen and the lady selling the goat didn't know they were there until a prospective buyer looking the doe over found them. If I remember correctly, they are several little hard bumps on one side. I had forgotten about it and now that I remember, I'd like to find out more about lumpy, bumpy udders. The lady said the doe had never had mastitis or any other problem. Any ideas?
