Growth on ewe's udder

[Southdown]

My ewe, Daisy, has a growth on her udder. I suspect that it started from the lambs' teeth cutting into her as they nursed. It first looked like the teeth of the lambs were cutting into her and now it looks more like a wart.

Ideas?

It's hard for me to make it out with your photo...think I'm seeing the growth, but not sure. Haven't seen that here but hope someone answers that has experience with this.

It's a poor photo, but what you are seeing is the growth. The actual teat is in front of it and not visible in the photo.
