He was definitely feeling froggy last night. I started out just mounting up and getting going, but I decided that he needed to get some of that energy out without having to deal with a rider, so onto the longe line he went. Still off, but boy, even off ... can that horse MOVE. I think we'll have fun with extended gaits. ;) He flicks his front feet out, even.
On the longe, I asked him to canter for the first time since he's been hurt -- four weeks yesterday -- and he was off, but he was also quite pleased to canter.
So clearly his brain and his muscles are ready for more than his leg is. I do think that working is the best therapy, so we'll increase the time and effort on rides.
Of course, then I start second-guessing myself. Again. Am I dealing with this correctly? Should we have an ultrasound done just to be sure we know what we're dealing with? Should I be walking him only until the swelling around the tendon is completely gone? I should not read COTH forum discussion about this kind of thing, because I hear everything from "it's nothing" to "OMG I only walked my horse for 2-4 months and only then did he heal!" Dr. Internet, DVM is not very consistent. :/ I wonder if I'm assessing his lameness as more severe than it is, or not severe enough. TM said she wasn't worried terribly.
I think more patience is in order. It's funny -- I'm comfortable with the path we're taking (heal the wound, controlled exercise for rehab of the leg) when I don't read about it. When I read about things, all these various situations come up, and I can't decide whether I should worry or not. So ... tincture of time, I think, and I'll know when to worry.
