The carriage horse industry has been banned in many major European cities. The reasons vary, but most commonly cited are:
1. horses spending hours breathing in heavy exhaust fumes,
2. risk of serious injury or death in a traffic accident,
3. poor or inadequate stabling,
4. little care or no veterinary care,
5. poor hoof care, and
6. a life of drudgery, boredom, overwork and depression, and
7. forced to endure extreme outdoor temperatures and weather conditions.
City officials became convinced, because of a steady stream of complaints from concerned citizens and tourists, that the lives of carriage horses were indeed abysmal, and they could not improve their lives, no matter how much the trade is regulated.
