I got hired to work with two young horses (a colt and a filly named Harvey and Carmen) out on a ranch. They are green broke (a year ago) and just sat around, so now I'm working with them. We know the majority of our groundwork, roundpenning, lunging for respect, yelding the hind/forequarters, sidepassing down the fence, sending, etc in the past couple sessions. Harvey is much more hard headed than Carmen is.
Well, even though he does the roundpen work flawlessly (The changing direction, facing me, sending, transitions) he will NOT stop when I say "Whoa". The majority of colts I have worked with, I work them long enough that when I say whoa they just yield their hindquarters, stop, and walk slowly to me. Carmen does this nicely. However Harvey just runs and runs and runs. I've tried yielding his hindquarters with the stick, and he just runs faster. I've tried doing nothing and just standing passively in the middle, and he just keeps going. Also tried getting in his "drive line" and he just change direction (No surprise since that's how I taught him to change direction) but dear god today I just walked out and left him there to run and he just kept running for another five minutes before settling and then I went back to catch him.
Anyone got an idea? O.O I was thinking maybe I should just keep him attached to a rope for now so I can folow through the "whoa" with the pressure on the halter.
