My donkey has a strange habit. In the past I have seen him drag around his pasture mate by the mane. She has since moved to a different home and now he is pastured with a 5 month old filly. I have noticed him doing this to her. He DOES NOT SEEM TO BE TRYING TO HURT HER. I just don't want to see her get hurt, I am not terribly worried as he is not much bigger than her. He is a 30" mini donk and she comes from a B sized mare and a shetland daddy. She is just absolutely the sweetest little girl and I want to make sure he isn't emotionally scarring her. Is this a normal behavior? He is such a love I can't imagine him trying to hurt anyone. Please tell me this is some normal horse behavior!!!
