CharleyBarley I had a pair of riders ask me not to put an umbrella up once because their horses didn't like them. This was on a village street, mid-morning, where it had been raining heavily since dawn. They shouldn't have been there if they had so little control, or if their horses were that nervous; which is what I told them. There is no shortage of open countryside or lanes around the village. I am a reasonably experienced rider and some behaviour is shocking.
I don't believe you.
Things young horses might be scared of (I've tried telling them its just normal things you might see on a village street but they asked me to train them): umbrellas, people jumping up and down on trampolines, kites being flown, people casting fishing lines, people throwing balls for dogs with those thrower things (don't know what they're called), model aeroplanes being flown very near them. In all cases, the horse is worried its going to be struck in some way.
My horse loves dogs. All dogs. He would ideally like to go up and kiss all dogs (cats as well) or lick them or whatever it is he has in mind when he tries to edge near them whenever he sees them. If I wasn't in control, I wouldn't be able to stop him. I can guarantee if he got bitten by a dog he would be terrified of dogs for ever more and no-one would be able to control him.
My horse is also racist. When he sees a person in a burqua, he is terrified, he snorts, loudly and bounces about so that everyone stares at him and its obvious what he is spooking at. So embarrassing.
But he's still not out of control just because he is scared. And if I can ask someone to stop throwing objects around while I'm riding past to lessen the risk, I will. I kind of hope people will have enough understanding of animals to know this kind of thing without being told, which is why I'm a bit sceptical of CharleyBarley's claims to be an experienced rider.
wonder what would happen if we let our horses run around loose, going up to people and sniffing them, while calling out "don't worry, he's only being friendly/he only wants to lick you
