I do not know how dogs do exactly but I suspect it is better to be a dog than a human being without unitary perception. For example, can we do nothing at all and not suffer ('What I will do in the evening', 'What I will do tomorrow') because we are not doing anything so called 'practical', to become somebody, to 'secure the future'? Dogs do not do such things, they do not even 'earn a living' and they do not have a problem with it. They are carefree. So who does better?
