How to stop my horse jigjog HELPPPP!!?

If she is acting that way close to home, she knows that you're going to put her away and feed her. Horses get excited over things like that, especially after working. Just continue to work with her. I had a barn sour horse who did that same thing, it took me two months to break her of the habit. I never used a saddle after the habit started. I would make sure to work her hard and walk her out before we got too close to home but if she started her little gait again knowing we were close to home I'd stop her there and run her out some more. It'll take time but im sure you can break her habit. good luck.
