The biggest Dog that ever existed - Epicyon

You've likely heard the term "Big Cats," which generally refers to members of the genus Panthera, along with two notable exceptions: the cougar and the cheetah. Together, these animals represent some of the most successful carnivores on the planet, with over 70% of countries having at least one big cat species as a top predator. This widespread dominance is no small achievement. In fact, the lineage of big cats stretches back millions of years, with the first emerging during the late Miocene, roughly six million years ago. However, big cats aren’t the only formidable carnivores out there. Another well-known group, the Canidae family—commonly referred to as "dogs"—includes domestic dogs, wolves, coyotes, and foxes. Like big cats, canids have a global presence. But unlike their feline counterparts, most canids are smaller in size. Even the largest wild canid today, the gray wolf, is only comparable in size to the snow leopard, one of the smallest big cats. This naturally raises the question: where are the “Big Dogs”? The answer is simple yet fascinating—they’re long extinct. But once upon a time, giant canids roamed the earth, thriving and dominating their ecosystems. 0:00 Introduction 1:27 The Giant Dog that ruled North America 2:20 Reclassification and unusual feline features 3:33 Three different species 4:04 Body Size 5:20 Crazy Bite Force 6:21 Hunting in Packs? 8:08 Bone crushing teeth 10:44 Range and Habitat 11:14 Animals it coexisted with 12:03 Interactions with other Predators 12:53 Reasons for Extinction
