Even in 1905, it could be hard being a pet. This Jack Russell terrier had to perform for its owners, sitting up and begging on a large wooden barrell. What an indignity this is, it is probably thinking to itself. But being good-natured, it accepts its lot. So if he was, say, five years old and alive today, he would be 110 years old today. But with each dog year being worth seven of a human's, he would be 770!
