Most canines, including these adorable wolf pups, are social animals with brains that have evolved for that purpose. This is why dogs are, on the whole, smarter than some solitary animals.
The Great Plains of North America is where canines first arose more than 30 million years ago. From there, they adapted to every landscape across the Americas, becoming furry polar specialists, gnarly Amazonian bruisers, and tango champions of the Brazilian grasslands. Follow biologist Patrick Aryee across the western continent as he gets face-to-face with a pack of wolves, bundles up with an Arctic fox, and plays hide-and-seek in the rainforest with the elusive short-eared dog.
