My good news is that both mares arrived safe and sound (and I still have all my hair) from their cross country adventure. The OTTB got her shoes pulled and is proving to be the sweetest creature ever. It's proven to be a wonderful breathe of fresh air from Herself, her hatred of the cold, and subsequent yucky attitude.
I also taught Herself the word 'cookie' so I can actually catch her! I'm looking forward to getting them both back to work as soon as the ground dries and we get more than a day of sunshine at a time!
Mare is slightly lame again, which isn't happy, but...
We are confined to walk-only rides of 30-45 minutes. I am even taking a walk-only lesson once a week, and it's SO helpful for both of us Mare is working off a light leg again, I'm getting a lot better at steady contact so she will go along on her preferred contact (light but connected) rather than trying to evade it. We like each other again
Of course I am sad that she is lame, and a bit worried because there's not a clear answer as to why (except that the lame leg is structurally the weakest). The vet is doing one more ultrasound and if that doesn't make things obvious, we'll go to a referral hospital.
