Here's to the best outcome... I don't know what to hope for with whether she should see him. A diagnosis would be good so you can stop wondering what's going on... and perhaps have a clear plan.
She said it's definitly the stifle.
Her plan, first try exercise. 10-15 minutes every other day, working him over 3-4 cavaletti's. First week just at the walk, then 2nd week at the trot. I should see some improvement, if not, she wants to see him.
She said there are alot of things to do rather then clip the ligament. Blister it to make some scar tissue to tighten it up so the patella can't slip out.
Can 1 week of every other day at a walk for 10-15 minutes do anything? That almost seems pointless to me, but I'll give it a try.
