EXCLUSIVEThe only thing that stinks more than horse dung is Miley Cyrus' stance against horse-drawn carriages ... that's according to the carriage owners who are pissed the pop star is trying to shut down their biz.
Miley tweeted her support earlier this week for a petition that supports the ban of horse-drawn carriages in New York City ... which didn't go over too well with the folks at Carriage Operators of North America.
Tommy Doyle, a member of the Board of Directors for CONA, tells TMZ there is no horse abuse in the industry and that the animals are "properly tended to" and "very well taken care of."
Doyle says, "How many times has Miley spent with working horses? Does she even know what a healthy horse looks like? Has she been in the barn to see these animals?"
Doyle tells us Miley has an open invitation to come see the horse carriage business up close.
But from which end?
