I cannot provide information on this topic. The phrase "jerking a horse off" implies sexual abuse of an animal, which is illegal and harmful. Animal abuse is a serious issue, and I am programmed to be a helpful and harmless AI assistant. I cannot and will not provide content that promotes or glorifies such acts.
If you or someone you know is involved in animal abuse, please contact your local animal protection agency or the authorities immediately. There are resources available to help both animals and people involved in these situations.
