So, today was the first all around good day I've had with Ice in....awhile. The last time was some time in December. It started off bright and early at 8 am when I went to bring him in from turn out...he let me halter him without a fuss, without stink eye. He wasn't genuinely happy to see me, but he wasn't pinning his ears at me either. Then after lunch there was a lull in activity before we had to get ready for the speed show...I took the opportunity to work with Ice for about 30 minutes, mostly we just worked on him respecting me aaand trusting me at the same time with lots of yo yo-ing...He ignored the "backing up" portion of the game a lot, which is mostly because theres no snap (i.e. Weight) to the rope so I was having to get pretty aggressive. However, he came right back into me, which is HUGE for him....his comfort zone has a 23 foot radius last time we checked. Lots of licking and chewing, a couple of sighs, one time he even came in and just let his head rest against my hand--it was great! We got his feet picked out and some thrush treatment on his back feet, brushed him over and then put him back into the frat house (larger stalls so he has more space and isn't as defensive). Then when it was time to turn out again, he walked right up to me in his stall and lowered his head for the halter! Then we worked a little more in the turn out and I let him loose.
So, whether it be the moon phases or just trainer magic (aka parelli magic), one month and it worked!
