Almost Four Months

I just looked back at the date that Muddy first showed being lame. It was May 31st. That means at the end of this month he will have been lame for four months! I find this alarming. He got his fourth Adequan injection on Thursday. I had him trot for a few strides to see if he was still lame and he is. He doesn't seem in pain or unhappy. He still gets around very well. At the walk, he's sound. I guess I need to start thinking up some things to test or do to figure out why he's still lame.
