My poor bunny started growing something under her chin a couple of weeks ago...it's hard, pink, the size of a golf ball, and has lost all of the fur on it. She doesn't seem to be in pain but I know that's just a natural defense mechanism they have. I really don't know what it is and was hoping that maybe someone could help out. I realize nobody's posted on here in about a year but it's still worth a shot right? If anyone knows or has any idea what it may be please tell me, I'm very concerned about her.
