The anthropocentric approach of animal treatment brings it to this level as shown in the video. The horse barely managed to walk and did some uncoordinated head movements, showing stress and fear.
The exploitation/use of animals, which are sentient beings, likewise humans – should not happen in this way, without addressing or considering any aspect of their welfare; the best measures should be taken, in favor to the animal, before we use it for useless commercial pleasures/entertainament (since not using them at all, for these illogical reasons, is out of the question for our society).
