Hosing down the horse on a hot day?

it's nice to hose a horse off on a hot day, and it's alright if you scare him a bit it's something all horses need to get used to. Just be careful and get the job over with. If you think he's afraid of just the hose then turn it off and let him sniff it and rub it on his neck and over his back a bit to show him that it won't hurt him. Then, turn it on and spray it on the ground so that it's not touching him. Wait until he's calm and then start hosing him off from the feet up. I think he really just needs to get used to the water a bit more. It should get easier every time too.
