totally loved the sprints. I'd thought earlier in the day that he seemed a little better when i had him out for his potty breaks but chalked it up to wishful thinking. My theory is that after hiking around on the rougher terrain at Edgeworth for four days that the smoother, less grown up home ground felt like a piece of cake.
I finally did hear back from Dr. Sherman after we got home and he said this was all not too surprising to him, that it tends to corroborate the habit theory. I got a more concrete plan from him and am to keep the boot on for two solid weeks. We want Zac to get really comfortable with the off leg and i'm to resist the temptation to test it. We'll stick to the long hikes and sprints, adding extra challenge as i can find it (rough terrain, etc) and touch base next week, and go from there. Sheep work will have to wait until we have him balanced up on both legs. I'm feeling really encouraged.
Making it an even better evening, I worked Bart a bit and he looked like a million bucks, and wasn't lame at all afterwards. A very good evening all around!
