Today another stablemate and I went for the same walk off property, this time a mare with my gelding. To my surprise at about 7 minutes out he tried to turn around to go home. I tried just sitting til he got bored, but I could not get him to move forward. He backs up when he's nervous. After messing around on the road we decided it was safer to dismount and continue walking up the hill leading in hand. That seemed fine. We turned around to come home, and I remounted.
I meant to walk past the driveway but this horse just kept getting more upset with me. Began backing into the fence, felt like he stopped using his brain.
I hopped off again and in hand, took him up and down the road passing the driveway about 6 times before I let him go home.
Do horses have favourite buddies they will trail with, or is it just a little too soon for him to get comfortable either with me or off property? We do a fair amount of groundwork and clicker training. Its helped with him not pulling back when he's nervous (sunscreen, flyspray). Otherwise, he is great.
