I turned Drifter out in the arena to stretch his legs this afternoon. He moseyed around a bit, then decided the damp sand was just right for some good rolling:
And then, he saw the goat . . . . much running around ensued:
I had a fecal test done on Pie and Drifter, and Pie came back negative - he was negative in the fall - and Drifter came back as a low shedder with some strongyles. I wormed him with Equimax at our vet's recommendation - it's one version of an ivermectin plus praziquantel dewormer - and we'll do another fecal in three weeks as well as making sure his paddock is thoroughly cleaned every day so he doesn't reinfect himself. For more details on what we're up to with our deworming program, check out this post. Until we do the next fecal, he'll stay separate from the other horses - since both Dawn and Pie were negative, it's a pretty good assumption that all of our horses are negative. I also e-mailed Drifter's former owner so she could deworm her small herd, as it's likely they're infected too.
It's increasingly clear that I need to take things very slowly with Drifter. I need to ask him to work, but do so in a way that gives him the opportunity to be successful and doesn't result in too much tussling. After a week, he's still pretty nervous and reactive and leading him isn't easy - I'm having to get big too often to keep him from mowing me down, which means I'm pushing his limits too much, too early. I need to dial things down a bit, and if that means all we do for a week is stand around in the parking lot right next to the barn door, that's what we need to do. I need to let go of expectations and just move as slowly as he needs me to go. This may result in faster progress in the long run. I'm also going to consider putting him on some magnesium oxide as a supplement - this often helps nervous horses - if he were getting grain, which he isn't, I'd consider B-1 as a supplement.
