I live on 37 acres with my boyfriend. His daughter lives on the property also. She has a male horse that she got around 8 months ago. Yesterday My boyfriend bought me a paint for Christmas and suprised me. I am so excited I have always wanted one. She is a gentle horse. This morning I went over to check on her and when I tried to get through the gate the male horse wont let her anywhere near me. Everytime I tried to get near her he bit her and chases her off. What do I do? He is not my horse and he is very big!!
