Besides the fact that these horses collapse, Carnegie believes that the carriage industry is generally very hard on the animals.
"These horses are standing on ... asphalt, for at least nine hours a day, inches from traffic, and they are wearing a bridle and aggressive metal bits in their mouths for a minimum of nine hours straight," Carnegie said. "That in itself would be considered by most caretakers abuse."
"That's not even factoring in subjecting them to traffic, loud city traffic, the fumes from cars," she added. "Many of them [the horses] hang their heads low and just breathe in the car fumes. Many of them are eating feed that's contaminated with pigeon feces, and many of them are eating feed off the asphalt itself, which is on the two-way traffic street, Central Park South."
At the moment, it's not clear what happened to Max to make him collapse, but NYCLASS is asking for a formal investigation to occur.
