Don't know the Title. But the wintry cover has the bottom half of snow (?), and there are two Jack London-type trapper outdoor men on it, plus a dog and a cabin (house?) in the background. Does anybody know the name of this book or the author so I can buy it? I read it in the early 1973.

Sounds like call of the wild

I searched Google Images of London's book covers, and agree with paraclete. Call of the Wild makes the most sense, even though I couldn't find the exact cover you remember (but I came close!).
