Like obedient pets, people can be trained to be useful too. All you need is a little auditory stimulation and an important duty to perform, and you can make every human within earshot as helpful as Lassie. Though you probably can’t make them as cute. On the flip side of the coin, humans have hands, so they can do more things for you. Unlike a dog, which can’t offer much more than a good face licking. So it depends on what your priorities are.
