Congratulations to the person in the video ... a dog owner with a well-trained, well-disciplined dog. So there was a good outcome.

But if the dog was not well trained, and this went into a dog-wolf knockdown fight, it could have been a huge mess, with everyone getting injured (or worse).

I would not recommend that a person take dogs into wolf country. Why do this at all?

Just my 0.02 cents.
