Whether the horse's owner's methods are right or wrong are a moot point.
What is the point is that this is none of the OP's business. Whether you or I agree with the method of handling or not
On my drive to the farm where our horses are kept, I pass many many horse farms.....and I disagree with how alot of these horses are kept....i.e. Paddocks a mud pit, junked cars in field, no daytime hay supplementation now that grass is dormant in my area, none with blankets, some with no run in sheds, overcrowding of 11 horses in a small paddock, etc....the list can go on forever.....So, I could come up with a list of things a mile long that I disagree with, but really...who cares? If I stop and make suggestions to the owners about what I think they should or should not do, I am going to make alot of enemies and nothing will get changed anyhow...and I could even get shot! Bottom line, NO ONE is going to change their methods because YOU don't like it. You can buck and rear about it now, but in the end you will see.....the world does not need to follow your rules, and it wont. Maturity is achieved when you can come to accept that.
