I used to do the afternoon feed at a dressage barn in exchange for lessons. There were a few horses there that inspired me to wear a helmet and gloves while handling on the ground. One was a large pony that had been on stall/round pen rest for over a year and was understandably sour about life. It took one trip from round pen to stall with her rearing and those front hooves kept coming towards me at head height no matter how quick I was to bend her away to convince me. Helmet and gloves are a psychological boost for me. I’m calmer, and in turn can calm the horse. Solved the issue with the pony by donning helmet and gloves and arming myself with treats and a dressage whip. Took a few deep breaths as I ascended the hill to the round pen and went in with a big smile and pretended that leading her in was the best part of my whole day. Some preemptive halts and backing and freely dispensed treats as a reward and we had a whole new relationship. lol. I ended up being the only one she DIDN’T rear with.
Maybe I run in circles with an overabundance of young, green, nutty-buddy horses. But I’ve seen more than enough that I always wear a helmet lunging, loading, etc. And always with our draft horses. Our vet knew a family that had full blood drafts for pleasuring driving. One day, one of their children got kicked in the head and died instantly from the blow.
Eta: A while back I was walking on my horse in the indoor when the trainer poked her head in with a puzzled look and asked if I didn’t want my helmet. Realized that I still had my woolly hat on and not my helmet. I about had a heart attack and dismounted immediately. I think that’s the first time in 25 years I’ve forgotten to put my helmet on before mounting.
