So frustrated, I feel like giving up. *Rant/Vent*

They can change over night but they don't a complete 180. And just cause its self care doesn't mean someone wouldn't mess with your horse.

Sorry.... I wouldnt do this to my horse...but its a free world,,!

Sorry, I'm going to discipline my horse.
Being walked all over by a spoiled 1000 animal isn't my cup of tea.

A couple of questions:

What was different at the stable?
Is he alone at home and around other horses at the stable?
Did he spend more time out, or in a stall at home? At the stable?
Is there more activity, noises, sights, animals? At the stable, than at home?

You can change a horse's environment and they sometimes need time to adjust. How many threads do we see of people taking their horse to a show environment and having a totally different horse than at home.

Unfortunately, if he was just being excited/silly and he wasn't handled assertively, then it easily could have sent the wrong message and gotten quickly worse.

Sounds like he's at least a little more himself and you just need someone to help you get your confidence back.

Keep us informed no matter what you decide. I wish you the best...

I think something physical happened to him. Not saying anyone did something but he could have gotten himself cast, rolled on a rock, bumped his head in the dark, eaten a funky weed-any number of things.
A sudden change in behavior warrants a vet work up, ideally from a vet that knew him before the changes.

At home he is kept alone, he's kept in the pasture or paddock (he's an easy keeper and has foundered in the past and is currently off grass at our farriers reccomendation, so being kept in the paddock).
At home he is also kept with a goat occasionally, but they don't really care for each other.

At the stable he was in paddock that was adjacent to other horses paddocks.
I kept him outdoors 24/7
New sights ect: cows, other horses

I have taken him to gaming shows before, and he was perfect. He didn't act any different at them than he does at home.

I will say that even at self care someone can totally mess with your horse. I had an arabian mare at a self care place. One of the boarders decided to give all the horses a treat and fed them all beat pulp she did not ask she just did. My horse had a bout of colic. One tranq, tubing, rectal palpation and farm call later she was fine. I was ticked because who feeds someone else's horse a new diet without consulting the owners? Lesson learned some people are weird.

I wonder, do you have other horses at your place or is he alone. Perharps when you took him to this stable he got buddy sour and didn't want to leave the other horses. They can get downright nasty if they are buddy sour, and the farther you get from the barn the worse they are. Just curious.

Nevermind, see where you posted it. I would go with buddy sour, happens all the time when horses that haven't been around horses suddenly are. The trick for it, I had a horse like this, is to ride a little farther from the barn/buddies each day, just to the point where the horse gets uncomfortable (starts to act up) and then turn them around and go back but do NOT put the horse up, keep going back and forth, back and forth, a quazillion times till they began to quiet and only put them away then. Since you have brought your horse back and he is still being bratty, my guess is he's established a little bit of a bully behavoir with you. Any horse you get, no matter how well trained they were, can revert back to being naughty. If you don't have a lot of experience get a trainer to help you. I think he's probably totally fixable, he just needs some readjustment by someone with experience. It would probably end up being better if you get some retraining done on him, then have to invest in selling and buying of another horse, plus, it may save him in the long run. Many a good horse goes down this road and never comes back because no one invests in them.

Subbing.

Wishing you well. I'm going through the same exact thing with Spirit except she hasn't been moved. She went from a good honest ride to nuts. Vets been out and ruled out any pain issues. She's constantly shaking her head and body like 100 flies are on her and she lays into trees to scratch while I'm on her. Been going on for 2 months now. Trainer rode her and said she's a handful. Wish I was more experienced to help her through this but I can't just make up experience that I don't have. She has to die for ground manners and is excellent in the round pen excercises. Somewhere she decided she didn't want to trail ride anymore. Even with her 2 other pasture mates on the trail, she's horrid. Going to see if someone wants a free lease "project horse" but I doubt I'll get any takers. It's a painful thing to know that your horse needs you and you don't have the skill set to deliver.
