Let's talk about this. Mr. Henry is about 6/7 years old and he has always been a mouthy and just overall odd little horse. I literally described him to clients as autistic. He has little to no social skills in the herd and is very easily over stimulated and overwhelmed. He absolutely does not respond well to harsher handling or domination games. He's not very confident in himself either so if he feels like he's doing something that is wrong or makes you unhappy, he shuts down or gets aggressive. I've been working with him now for a little over 2 years and my style with him that really seems to work is keeping things light and fun and playful. I do my best to not set him up for failure and to build his confidence. I think he was either an orphan baby or was started way too young and cowboyed/fried his mind. But whatever happened to him or what his story is, he loves to do the right thing. When he was in the program I was managing he was constantly biting clients. The problem being he's not a big fan of pets or face rubs. In fact, he hates it, and clients would never respect that boundary so if he couldn't physically move away from them he would often bite them. Which I think is relatively fair. Horses have certain boundaries and if you can't respect them then you're asking to get bit or kicked. Clients would take a hold of his lead rope and immediately he would start biting the lead rope. I would take the lead rope back and he would immediately stop. This is essentially how I became Henry's mom when I left the program he came with me. Now. He KNOWS that mouth contact on human body parts is wrong. As he's doing it he's already expecting punishment for it. There are times where it literally looks like compulsive behavior. For example, today I was taking him for a walk through the recently harvested soy field and there was a pretty good sized ditch. Henry loves to jump so we jumped it and because he was so pleased with himself, immediately upon landing on the other side he reached over to nip me. I don't believe in hitting horses in the face so my response is usually to make an angry AH AH AH noise and immediately get him to back away from me. Most of the time he's already backing up by the time I increase my pressure. It's not even a matter of a training issue at this point. He knows he's not supposed to do it but he literally cannot himself himself. I'm hopeful as he ages and has more consistent handling and gains some confidence, this will slowly take care of itself. He has never had one single owner consistently asking the same thing from him and there has already been a big improvement in his overall mental health since moving him to Ohio with me. So. How would you address this if it were your horse?
