That's how I had to tackle Bear when he came here at 8 months old; he was terrified, but like you, patience and consistency paid off and he turned into a smashing chap just like Ted is doing. It won't be long now, he's turned a huge corner already in those few days.
Just as we turned the huge corner, I have managed to ruin all the work that got us there in the first place. Ted panicked this morning as I was turning him out, the gate stay rattled just as I was unthreading the rope from his headcollar, I couldn't hold him and off he went with some of the rope still attached.
The paddock is tiny but he lost the plot totally, the rope (soft one) was touching all his legs. After what seemed an eternity, probably 5 minutes, he stopped and allowed me to get it off, but he is a wreck. If the wind rattles the dock leaves he is jumping and running. I doubt very much if he will be caught this evening.
Apart from having a good cry out of pure frustration, I really don't know what to do now. Do I leave him be for a couple of days and hope he settles down, do I try to catch him and risk him breaking away again on way to yard. If he get loose in yard he will be in trouble, there are obstacles like tractors etc,
do I put a short piece of soft rope on the headcollar and leave him to de-sensitise himself. (this thought comes from watching him panicking, he did stop and graze before the rope moved and set him off again).
I was doing so well, managed to touch quite a lot of him, even down his forelegs and ears. He has led in and out nicely and even had a little walk in the yard.
Flipping horses, what with feral Ted, the big horse came out lame this morning, thankfully the ligament is intact, lame in foot, and the yearling filly in a cast, I am beginning to wonder why I bother.
All ideas on handling traumatised Ted very much welcomed, over to you ....
