This is an extremely dangerous animal and should be destroyed immediately.
Wolves have a great degree of raw intelligence and pack coordination to conduct elaborate hunting operations. They are intellectually on the same par as a five year old child. But they go to great lengths to avoid human contact.
Coyotes have a different order of intelligence, entirely. They are expert tacticians, and will plan and execute schemes which they will fearlessly use against humans. They will even pretend to be friendly and have no problem operating in suburban or even urban areas.
These two mixed together would likely defeat an equal number of large fighting dogs, and an armed adult human would have to be very careful to avoid any area with concealment, lest they be attacked by several animals from several directions at once. It is likely that they would even take the human’s weapon into account in their strategy.
Any area where these animals are sighted should be placed off limits for foot travel until they can be eliminated.
I don’t doubt they’re a threat to man. This is the first I’ve read of them and am going to do some further looking.
Dude, unknot your panties. It's a dog. Yes, they can be dangerous, but you (apparently by being on the internet) are self-defined as a human as the Ace #1 Killer on the planet. Kill them. Eat them. Do not fear them.
Hell, humans keep carnivores for pets, almost exclusively. We're the bad-asses on this globe.
