" The playfulness and joy of a dog, its unconditional love and readiness to celebrate life at any moment often contrast sharply with the inner state of the dog's owner — depressed, anxious, burdened by problems, lost in thought, not present in the only place and only time there is: Here and Now. One wonders: living with this person, how does the dog manage to remain so sane, so joyous? "
