Pets: Our Closest Companions

Humanity's connection with pets goes back thousands of years. In fact, evidence indicates we've been keeping dogs for at least 14,000 years. Today, more than two-thirds of American households own a pet. We love our fluffy companions and the technology we've developed to adopt, relocate, resurrect and communicate with them is proof that the value of their companionship is immeasurable.
