Cats versus dogs. It’s an age-old argument that has broken relationships, turned roommates against each other, and even spurred an anatomically questionable Nickelodeon show. But even the most hardened cat enthusiasts can’t deny there is one trump card in this classic debate: puppies. Competing head-to-head with babies for the top spot on the list of “cute things everyone loves,” puppies bring an earnest playfulness to any room, as well as the capacity to transform a mediocre moment into something to smile about.

Interestingly, the extent to which we find dogs, and puppies, cute could be tied to those babies more than we think. Characteristics like large heads on small torsos, big round eyes, soft body parts, and propensity to stumble are universally cute; that's to say, the same harmless, childlike "cuteness factors" as the human babies we intrinsically care for.

To honor these sultans of sweetness, Stacker compiled photos of the American Kennel Club's 50 most popular dog breeds when they were just pups, using the 2019 popularity rankings released on May 1, 2020. For good measure, we've also included details about what exactly these furbabies are like, from temperament and energy level to obedience.
