Canadian Trail House makes a
collapsible horse bowl with a long tether for filling with water when you can't
get close. Great for vet checks for mixing wet food. Folds up and goes into a
net bag with snap for attaching to the saddle or vet check bag
Tip: The big 72 oz. collapsible nylon dog water
bowls by Outward Hound (available at pet stores, but usually sold out) are
great for dumping your baggie of grain and adding a little water to
feed/hydrate your horse on the trail (and keep your hands clean). It
has a loop, so you can clip to saddle or just stuff it into pocket or
pouch.
