Enhydrocyon is an extinct genus of bone crushing canid which inhabited North America during the Oligocene and Early Miocene, 30.8—20.4 Ma, existing for approximately 11 million years. ^[1]

Enhydrocyon's dentition suggests this animal was a hypercarnivore or mesocarnivore.^[2] Species of Enhydrocyon were relatively large, powerfully built carnivores with a short snout and deep jaws reminiscent of a jaguar.^[3] These features give the skull a shape resembling that of the extant sea otter (Enhydra), prompting the scientific name.^[4] With an estimated weight of about 10 kilograms (22 lb), this was the earliest genus of canid adapted to be specialized predators.^[4]
