I decided not to take my lesson on Day 11.
I thought it would be more fun to have my car break down as I was driving to work. This left me with no transportation to get me to the barn on that day at all. Of course this really bummed me out but there just wasn't anything I could do about it. I was able to get a loaner car later that evening, so I had transportation for Kaswyn's vet visit the next day.
Here's how the visit went. Kaswyn flex tested slightly positive on the left front. But that was all. Doc said he hadn't seen him this sound in years. But I said that I knew he was in pain, and Doc didn't dispute that.
We got x-rays of the foot, and compared the same shots with x-rays from 2010. This revealed four important findings.
#1 The navicular disease had progressed past the point of the neuorectomy, so that pain and swelling of that foot was now being felt by Kaswyn, causing him to favor that foot and not put as much weight on it.
#2 By using the computer measuring system on the x-rays, we were able to clearly see that the angle of Kaswyn's coffin bone had rotated 3 degrees down.
#3 His heels were narrower by 8 mm.
#4 The dish in his foot was more pronounced.
To rule out deep digital flexor tendon involvement, he ultrasounded the tendon. He said it was totally normal.
Doc thinks it went this way - the disease progressed, causing pain the the foot. Kaswyn began favoring the foot, which caused him to bear less weight on it. This caused decreased circulation, and resulted in the narrower heels, pronounced hoof dishing, and rotated coffin bone.
The solution? Better anti inflammatory management and slow change in shoeing. Kaswyn is now on Previcox, the canine pill form of Equioxx, which works just as well, is cheaper than the horse paste version, and is much easier on the stomach than bute. He is also on EquiThrive, a powdered neutraceutical that uses natural products that possess anti inflammatory powers.
Kaswyn is much better traveling to the right, so Doc said to work him to the right on his regular schedule for a week. Then work him a bit to the left and see how he is. If he's better, slowly introduce some left direction work. If he's still bad to the left, stop the left work and go back to the right work only for another week.
Overall the prognosis is good. If we can get him to start using that foot again we should be able to change the angle back and get the heels widened again.
Because of the vet visit I didn't have time to ride Phil. I guess that would have to wait for Thursday. I was going to have a lesson, but decided that since I hadn't ridden Phil in 3 days that I should ride on my own. My trainer couldn't fit me in anyway.
Tough few days, but we got through it.
