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.

Someone had to say it.
It is a canine, but judging from the almost pure wolves and pure coyotes I’ve had dealings with in the past, this is no ordinary dog. And there is also a situational element at work. An animal of this sort is closer to the European wolf than the Gray wolf.
In 1871, the Russians recorded over 160 people killed by such wolves.
Add to that the failed United States effort to eradicate coyotes, who now range from Panama to Alaska and have even been found in Manhattan. In Texas, they have cross bred with dogs which gives them the ability to mate year round instead of just once a year. They mixes are regarded as more dangerous to livestock than pure coyotes. Packs of coyotes have been known to taken down adult Elk.
Since the 1970s, there have been over a hundred reported attacks of coyotes on humans in California alone, and such attacks are most common in just the last few years.
So what a coyote-wolf mix might present is a pack of animals that will stalk and make a coordinated attack on one or more people on foot, and likely at night. They will detect humans at about five miles, with a favorable wind.
I think the guy is talking about unarmed idiotic nature-naive foot travel.
