Coyote

A coyote was an animal native to the United States. According to Loomis Teague, they posed a significant threat to humans, particularly those who got lost in the hills after nightfall. (NSA: Peacemaker) Indeed, the Fourth Doctor was once perplexed by a pack of coyotes who passed he and Leela by in the middle of a New Hampshire winter. He reasoned that something must be wrong with the animals since they didn't attack he and Leela at a time of year when food was scarce. (PDA: Drift)

Despite — or perhaps because of — this reputation, the Doctor was known amongst the Pawnee as "Brother of Coyote". (NSA: Peacemaker)
