Human Names for Dogs
You’ll notice that many of the names on this list are people names as well, and would sound equally at home on a baby as they do on a puppy. Why is that? Our data shows that each year, dog lovers increasingly turn to human names for their pets. This reflects the larger cultural trend that embraces dogs as full-fledged family members rather than “just” pets.
In the past, male dog names and female dog names alike were less likely to be personalized to the dog. For instance, a boy dog might have been named Rex, Duke, or Rover, while a girl dog might have been called Lady or Princess. Nowadays, however, you’re more likely to hear Oliver, Omar, and Olivia called out at the local dog park.
