So when you send a child to bed with no dinner is different? I guess I was raised in a more old fashioned house hold. There is nothing wrong with withholding water and food from a horse for a day. When I first got my horse she was wild, never seen a human except for maybe twice in her life. She was two and when we brought her home we kept her in the trailer for a day and a half and when we led her out we took her straight to water to let her know that we are here to love her and take care of her... its a step in earning her trust, and that plus a few other things I was riding her in three days. I know that everyone trains different and I completly respect that. I just don't want to be made out that im cruel to my animals. I love them with all my heart. I was brought up to train very very old fashioned. I learned from my grandfather. If you have something that works though, that is all that matters.
Guess you have never had watch a horse colic due to dehydration.
Even our NPO horses at the hospital have water in front of them at all times.
