@June: That's amazing!

The only thing that bugs me is that the head/neck doesn't move.
@Luzien: Yeah, I've read about most of those issues when it comes to feeding. Also from what I've heard washing out the sugar from the hay is actually quite in-effective, unless you literally soak the hay for really long time, but that also takes out some of the nutrients... So I wouldn't put too much efford/concern into it. As you said, it's quite hard if you don't have certain resources. We got couple dust sensitive horses at the stable and it's only possible to water their hay in summer. In winter all horses get hay silage though, so it's not very dusty.
Keeping fingers crossed you'll be able to get to the clinic soon. It's so much nicer to know how things actually are, rather than keep guessing.

Finally went to ride.

Still not ideal conditions, but at least it's not total skating ring anymore. Next to the fence was pretty good as the snow had somewhat packed on the ice, in non-slippy way. The middle was though ice with only loose layer of snow, so didn't ride much there. Went pretty good, Heta was much better than last time too. Mainly walk/trot/tolt. I managed to sit the trot pretty well too, my feet were pretty still too which I'm quite proud of. Though for some reason my left foot moved more than the left... I also tried little bits of canter on the long sides. That went pretty well, though Heta has definetly gone few steps back with the left lead. : P The canter didn't feel so good to the arm, but it wasn't too bad not to do. XD
We also did short trail ride after riding little over 30 minutes on the arena. I originally would have wanted to canter one hill, but the ground was pretty bad(little snow and again slippery ice under) on that path and Heta's hind feet even slipped few times in walk, so desided not to. And 'poor' pony was huffing while climbing and already sweaty from the arena work. >_< Though she did move in pretty good pace and tried to even trot a little, so maybe not so tired after all.

This bit of road had nice snow coat, but too short to canter and after the curve the road goes down hill pretty steep. : P
