If it works for you, great! It may not work for me. Pretty much everything we do with, to, and for horses is unnatural for them though some of it is for their benefit. I think most of us have the best intentions with the way we care for our horses.
Yeah & you know what they say about best intentions & the road to hell...
I think most people that mistreat their animals also have the best of intentions, they're just ignorant about what's wrong with their ways, or of better alternatives. That's why learning what natural is & considering the differences & effects is important, so we can make more informed decisions about the choices that we make.
Eg. shoes aren't natural & upon learning about natural function & anatomy of hooves, I feel they're *generally* not for the best, but understanding these principles can help me make better decisions about when & how to shoe for best results & least 'side effects'. Fences aren't natural either, but even convenience aside, I don't know that there are many places in the world that it would be safe to allow a horse to be loose all the time, but understanding their natural need for free movement, the way they interact, etc, we can consider how changes to fencing & paddocks can be made for the better health & wellbeing of our beasts.
& loose horses & Joe's comment reminds me....
biggest mistake people make is thinking a horse is a dog.
Had just had a great day's trail ride in a place that was indeed safe to allow my pony to just run loose while my friend & I rode our horses. When along comes a ranger. She said "Could you please put your pony on lead, because there are other people walking on these trails & he might jump up on someone who doesn't appreciate it"
Obviously not a horse person!
