This can be a toughy, or it can be painfully simple! If the cow is with others, she will try to mount them and stand while they mount her. That's the simple. If she is by herself, she will behave diferently. She may walk the fence, bawl, have a faraway look in her eye, have a clear mucus discharge and the real painfull one, try to mount you. Each animal is different and they all behave differently. The only thing they have in common is the riding and standing to be ridden.
