I feel your pain. I haven't been able to do much with my 3 yr old since December due to the mud and lack of a place to work him with dry, safe footing.
I worked with him on the ground the other day and ended up in tears. It was like he totally regressed. He even got away from me and ran around the property.
Spooky, disrespectful, not paying attention to ME, you name it! So I will either have to work him myself to try to get him back to where he was or hire someone to get him where he was before winter hit (hiring someone is what I would like to do). Before the bad weather he was at least rideable. Green but rideable. Now I don't know if I have the skills to get him back to where he was.
Selling has also entered my mind, but I love the booger and don't know if I'm to that point yet. I feel I need to exhaust all options before I re-home him. He was born here and I love him and feel responsible for him. Too bad he doesn't feel the same for me.
So yeah, I feel your pain. Glad it's sort of a "normal" problem though. This is my first (likely last) young horse. What a pain-in-the-behind!
