I think wind effects ALL horses!! Otherwise mine are all normal, except one who absolutely detests rain (and rain WITH wind is even worse!). Even if its a warm day, as soon as he even looks at rain he starts shivering. He gets so cold he simply cant stand still! Woose....
In some ways I am lucky Mr C is only effected by heat - but he does really suffer poor old hairy bugger.
Little C was amazing in the gales at the weekend whilst showing when you consider how young he is. He will work in the heat, but again he is designed for cooler weather.
