Well the BO thinks it's either a torn tendon sheath or a torn tendon. Vet is coming out tomorrow. She was just slightly off tonight but not enough that anyone else would have noticed. They gave her bute and wrapped it so she will be ok for tonight. Either way this will put me back money wise so this season will be completely out. Will have to see what tomorrow brings to know what her future is.
I don't think this has anything to do with the ride on Saturday? It was actually only 16 miles, I looked it up, and a good 7 of it was walking due to the other horse that was starting to be off. She wasn't in full work all winter but she didn't just sit around either. We had done 12 miles the weekend before and 6 a few days before that and then quite a bit of arena work. It was a mostly flat trail.
Her paddock is really muddy right now because of all the rain we just had so I think either the foot of mud or she slipped or something.
