Coydog

In the city of Teotihuacan, it was common practice to crossbreed coyotes and Mexican wolves with dogs in order to breed resistant, loyal but temperamental, good guardians.

[3] Northern Indigenous peoples in Canada were mating coyotes and wolves to their sled dogs in order to produce more resilient animals as late as the early 20th century.

[1] The term is sometimes mistakenly used for coywolves, which are common in northeastern North America, whereas true coydogs are only occasionally found in the wild.

[4] In captivity, F1 hybrids tend to be more mischievous and less manageable as pups than dogs, and are less trustworthy[clarification needed] in maturity than wolfdogs.

[6] A population of non-albino white coyotes in Newfoundland owe their coloration to a MC1R mutation inherited from Golden Retrievers.
