As a horse owner, I can tell you this is very stupod. Its rare for a horse to be able to handle the sights and sounds of a nightclub not to mention the close ceilings and furnishings without bucking or bolting. Maybe a police horse would do it. But very few others.
I have horses too and agree but I dont consider it quite cruelty but its foolish for sure
The horse could be a danger to people especially a stallion or agitated large horse
Or it could get hurt which then would be I supppose cruelty
A well trained horse could do it....Studio 54 used to pull this stunt
My 17.2 hand thoroughbred would be doing some serious bucking and kicking
Only my oldest boy can handle him....chestnut of course like Secretariat
Ive got a gentle giant Hanoverian who would probably be ok
A police horse some of which are really tall if well trained and controled l could handle it
They walk through Mardi Gras crowds
An agitated male horse prone to double barrel back kick is a dangerous beast no question
Very powerful twin pistons gonna snap and human in reach
