Wolves that I have seen from the air in Northern Canada were in packs of 8, 10 and 12.
The Russians used wolf hounds in organized hunts while on horseback. I’m not sure whether the ferocity of Borzoi is even still intact. But a book written in the past five years by a German dog expert said quite bluntly that a Borzoi in kill mode was terrifying to watch, and that this breed wasn’t recommended for people with small children, cats, or dogs smaller than itself.
And Borzoi, bred from Greyhounds, can out run wolves.
