After a little help from the vet school, it appears that he is feeling almost back to new! I rode him yesterday very lightly since he is out of shape, but he felt much, much better. He bent to the left easier, and was tracking up well. Happy day! So back to work we go! I have so much to improve on, but I haven't been able to really do anything because he was so uncomfortable. We got rads of his hocks, and he has mild osteoarthritis in both grade 2/5, but it's more pronounced in the left. His left fetlock also flexed mildly positive, but rads showed nothing on that.
Here's my handsome man!
