Thanks for all the replies, they are all really helpful :)
I was just wondering if you hose over your horse after a ride when he/she is really sweaty and what's the best way to dry? My riding school never hoses off their horses, the just groom.
In summer, definitely, but start slowly by running water over the legs for a few minutes, and then hose the shoulder and the neck, and gradually work your way backwards. When you have lukewarm water, like at racing facilities, you can hose more rapidly - the go-slow is about avoiding temperature stress. (Think about getting in a cold lake versus into warmer water!) If the horse's hindquarters aren't sweaty and the weather isn't hot, I don't hose those except between the legs where the foam builds up, and down the back of the legs.
In cooler weather, a bucket of warmish water and a sponge are good, just do the areas that need it. I dry using a scraper first, then I towel them off - they usually love the scrubbing. Head is always done with a sponge, never scraped (don't scrape the legs either, just the fleshy parts of the horse), and towelled dry.
Then the horse can go and roll - and it helps if you have clean sand for that, not the local black stuff!
Otherwise, walk dry before turning loose to avoid a dirt-encrusted result!
