I'm looking for some advice on what to do with my stud colt. He turned 9 months old yesterday and since about a week-2 weeks ago has become highly aggressive and strikes out with his front legs and rears while pinning ears and turns and tries to push you with his butt. He will do this in multiple areas including his stall the alleyway the arena and basically anywhere he feels like. We've tried multiple methods to get him to stop but he just doesn't listen to any of it. We've tried positive reinforcement and even negative reinforcement. I've watched alot of videos with horses that have the same issue but he doesn't listen to that either. He runs blind around the arena and refuses to listen until he wants to but he's worked daily and this only started around when he would have started getting testosterone. Does anyone know if gelding would help him be less aggressive?(he is also scheduled for professional training in march)

A friend of mine had a colt like that except he was the sweetest baby until he turned 2, after his 2nd birthday he became downright dangerous so she gelded him, a few months after everything worked out of his system he returned to how he was pre 2nd birthday so I do think gelding him might help, especially if there is no reason for him to be a stud (in terms of future plans)

Geld. It is not worth keeping him a stud.

Also, "we've tried everything" in a two week span is just not going to work for a baby (or any horse). He needs consistent training and handling, not positive reinforcement one day and negative the next. That's only going to make him more confused and defensive. Pick a method and stick with it.

Don't keep him a stud. He likely isn't thousands of dollars of rare bloodlines. No need to keep a stud. Just geld and get him in training

I'm a big fan of ball chopping. There's never a reason to keep a stud unless it's valuable for breeding imo.

I'd geld it for sure... it doesn't sound like his balls are worth the danger at all.

Apparently you can save the semen when they are gelded. Possibly talk to your vet if you're desperate for some offspring? Otherwise there is no reason for him to stay a stallion if he's that dangerous, because it will only get worse.

I completely agree with this

I wouldn't want to breed anything that's behaving dangerously.

On one hand.. 2 weeks is no where near enough time to for most of the given methods you stated to make any progress depending from horse to horse.. these things can take MONTHS to show even the smallest amount of progress depending.

Second? It sounds like the ball card needs to be cashed in if he's getting to a dangerous point. I would get him vetted first before anything, as my mare was on the verge of ending my life multiple times due to kissing spines. Obviously, that shouldnt be the case, but its a casual comparison. Another thing to consider before gelding is checking to see if he's done growing for sure. It can cause some issues if you geld too early, so just simply be aware of that.

Behavioral problems get pretty bad when they start off like that, and they can escalate extremely quickly. I've been flipped backwards on, trapped in between cement, thrown off, drug, kicked, bit, and the damn list goes on. All due to attitude problems.

Pleade be extremely careful, and do whats best for you. Your life isnt worth a replaceable animal.

Please excuse my spelling, I'm totally exhausted, lol.

Wanted to give yall an explanation deeper into some things I've said. When I say 2 weeks I'm talking about him striking out however we've been working with him since August on being very pushy and trying to kick I understand 2 weeks sounds like a short time but he strikes in his stall as well which also includes feeding time because I have self care board. This means in 2 weeks we've tried to stop him from doing it every time we feed, train, water, ect. I know that switching between only positive reinforcement and only negative reinforcement is confusing but in my training I always use a balance of both so the things I'm telling him are not new at all. The only thing I've tried to change is him rearing and striking because he had never done that the training would be new to him anyways. He does have amazing bloodlines and he's even homozygous for dun and overo but at this point I don't think it is worth the risk of him becoming even more aggressive if he's bred
