My horse's personal space is perfectly fine when leading and in her stall. However, the moment I take her up into the arena and I try to trot in hand she begins to 'lean' on me.
I've tried correcting her by physically pushing her while trotting and pulling the lead rope to the right (in quick succession). She generally gets the idea for a few strides before she leans again.
She's happy to flex for me, back up, walk on and trot on command but I'm looking to show her in hand this year and if she's leaning on me her straightness will be impacted.
So, how can I teach her to respect my space in trot?
I might also add that if I try to move her right in trot she becomes quite stiff. She doesn't refuse to move but it's certainly not as easy as turning left (if I'm on the left for example). I'm working at liberty to get her to move to 'Lay' (Left) and Right vocally, which I believe will help.
