Pony problems

I have an 11 y/o half- Arabian mare. I got her abotu two months ago. After i had had her for a couple weeks she didnt want to move forward but with two lessons and two weeks of work we were able to overcome it. However, I then went on vacation for two weeks and they used her for lessons. When I came back, she was great for two days then went back to not listening and not wanting to move forward.

Any advice? She’s learning my tricks. I do have a lesson scheduled.

Sounds like you need to not let your barn use your horse for lessons and, more importantly, find out from your trainer WHY your horse is stopping. Is it a health issue, training issue, or pilot error?
