Certainly could be a stallion. With all of the hormones, they tend to be more boisterous. It could also possibly be resource guarding - he sees you as a valuable resource and wants to keep you away from the other horse. With the severity, it sounds an awful lot like he has some anxiety or insecurity there and is determined not to let any other horse get close to you. There could also be previous experience/training problems, especially if the owner gave him attention when he asked for it or reinforced the behaviour you are experiencing with him.
As for what you can do... I'd recommend talking to the owner ASAP. It's their horse and if you & your horse are being put in danger, then the owner needs to take responsibility. In the meantime, is there any way you could put out some hay for him whilst you do whatever you need to do with your own horse? That way, he should be more interested in the food and will have a different resource to worry about, so his anxiety won't be placed on you. If not, I would recommend keeping a safe distance and a close eye on his body language. Have someone supervise if you can.
Resource guarding/anxiety can quickly become dangerous and the shirt tugging and pawing is a cause for concern. Without the owner's input, there's not much you can do since you don't know the horse's history, training, context of the behaviour etc. I would recommend counter-conditioning and ways to manage the behaviour if I knew what the context was but without that, there's not much to be said. All in all, talk to the owner as soon as possible and keep an eye on the horse. Stay safe and don't risk an interaction if you could be in danger. Good luck and please stay safe!
Thank you!
We are very annoyed with the owner, they don't appear to have been back since "Bossy Britches" as we've taken to calling him, arrived.
He is a very tall horse in ridiculously good condition so it all seems very strange. He must be a sporting horse because of the big well defined muscles he has and show quality coat.
He is branded but we don't know if/how that can be used to look for the owner or breeder.
We worry he's been stolen and dumped because he has nothing here, no leash or halter even. No blanket.
