Hellhound

A hellhound (Gigantocanis Swurii), also known as wargs, is a species of wild dog native to mainland Europe, but has since been introduced to Great Britain since 1520s and continental North America since 1670s due to zoo escapees and pet releases. They are the largest species of dogs alive today and among the largest canines in Earth's history, possibly descended from a group of hyena-like dogs that evolved into apex predators about the size of an Asiatic lion. They are carnivorous, feeding mainly on carrion, deer, goats, cows, sheep, antelopes, and even horses, but are shy and timid from humans. Despite how popular culture and myths seems to say, looking at them (including their eyes, for example) three times does not cause mischief or death nor do they leave trails of fire, since they are just normal animals most closely related to gray wolves.
