An owner at my barn has a horse that is between 20 and 25. She is blind in one eye and has been for her life. Recently she has beginning to have noticable lumps forming all over her. One on the throat and one near the poll are the size of a palm and are about an inch thick. The owner won't have her checked because he is afraid of what is is... What can this possibly be? Thanks,She isn't a grey but a bay thoroughbred cross mare. The lumps are under skin and hair.
