Of all the different species of animals in the world only humankind has managed to raise itself above the natural and perfectly rational desire to be happy. My dogs will not persistently do anything that does not make them happy. In the wild they would thoroughly enjoy hunting which is their equivalent of working for a living. Only human beings will accept life long boredom and misery so that a few people, who they probably have never even met, can be ridiculously happy. A gift, which most of the greedy bastards, waste completely and never, ever, say thank you for. Any other breed would turn on such useless and high maintenance members of the pack and throw them out. Humans are the most stupid of creatures. I don't know why dogs put up with us.
