Weaving is the horses response to anxiety and boredom. You already know that the horse is ok when outside but not in the stall. Can you just leave your horse outside? If not does his stall have a paddock attached to it. If so leave the door open so he can go in or out. If that is not possible buy a rabbit, a rabbit age an rabbit food. Place the rabbit on a shelf just below eye level in your horses stall. This will be a distraction to him and help eliminate boredom It does work!

hi Karen,
Sometimes weaving and other vices are caused by a lack of the for chewing,too.
So besides company and the possibility to roam, give you 2 year old enough hay to satisfy his needs of chewing. In the wild, horse have to graze up to 16 hours a day, head down, try to keep him occupied with this essential part of life. Just make sure he doesn't get overfed, choose a quality of hay with a high fiber content.
Keep us posted on how he's doing,

thanks for your advice unfortunatley we have no facility for all year turn out he is out for 1 1/2 hours in a paddock, he has as hay all day! ive just bought one of those plastic mirrors to see if that helps, i would be a bit worried leaving a rabbit in his stable he has already picked a hen up by his feathers thinking it was a toy!! do you think he may be doing it for attention he seems to stop if you go to his stable door then as soon as you walk away he starts again

Don't worry about having a rabbit The rabbit is in a cage. Goats are another companion that horses like Goats have a very calming effect on horses. Miniture goats would work if your horse does not have a paddock

Cheers

Hi Karen,
I still want to come back to a lack of movement, 1,5 hours of paddock seem too few for a young animal like yours. Company and natural movement will help him overcome this vice. Be creative and you'll find a solution that fits both the horse and your circumstances!

Miriam You are absolutely right about not having enough outside time. I would think giving the horse more time outside as well as a companion or at least a couple of play toys. We use a tetherball or a busy ball and hang it from the ceiling usually in the middle of the stall. It gives them something to play with

Cheers

Weaving and other stable vices, like boxwalking,cribbing or windsucking, are are stereotypes a horse will perform in order to release endorphines while having to deal with stress. They easily become habitual. It's very hard to break a habit like that, just like it is very hard for a smoker to just quit the cigarettes. The brain just needs that kick. In order to break a habit like boxwalking or weaving, you will ideally have to change the horses environment. In your case it would be best to keep the horse in an open stall, where the horse can go in and out as it likes. Especially with young horses vices like weaving can have negative influence on the physical developement of the legs and can cause problems in joints and on tendons. So, the others already suggested: Try to change the way your horse is kept and give it as much time outside as possible. The more it'll move around, the less stress it'll have inside!
