I don't want my horse to get into the mode - ho hum more water, there will
be plenty more so I don't need to worry, because when I go out west there will
not always be frequent water available. I want water to become very important to
him. The other benefit is if they drink small amounts much more often there is
not big swings in hydration status and associated fluid shifts in and out of the
gut associated with dirinking large amounts infrequently. It is important to
humans in prolonged exercise to drink early and drink smaller amounts more often
and I suspect it is just as important to horses.
As I said Truman , my method works well for me as I
am sure yours does for you , different terrain and different weather
conditions makes for different training methods .
