Up in the clouds
Is that really why though? Being stabled happily, like loading happily, is a fundamental skill for a horse these days and I doubt many people who have a horse that can't be stabled are happy about it or just "haven't bothered" to do anything about it. I've only known one who couldn't be stabled and he was a rescue who'd nearly starved in his so had good reason to hate them.
Saying its cruel to stable full-time due to worries about injuries or yard policy is quite different to saying its cruel to stable at all, not sure anyone on this thread has even suggested that.
I have only ever had one horse who didn't like to be stabled when we got her, she soon learned that it was actually rather nice to be warm and dry but I have said several times on here and I stand by it, one reason that I do not insure my horses is that I would not want to put them through any invasive procedure that necessitated prolonged box-rest. Many of those procedures have a very poor long-term prognosis anyway. I don't think it is fair to keep a horse in a stable full time for months when it doesn't understand why, even if it is well behaved in the stable.
