Even if the dog was the heavier of the two, his teeth and claws would be very much smaller and weaker and his hide less tough.

Indeed I have known of but one dog which single-handed encountered and slew a wolf; this was the large vicious mongrel whose feats are recorded in my _Hunting Trips of a Ranchman_.
General Marcy of the United States Army informed me that he once chased a huge wolf which had gotten away with a small trap on its foot.

It was, I believe, in Wisconsin, and he had twenty or thirty hounds with him, but they were entirely untrained in wolf-hunting, and proved unable to stop the crippled beast.

Few of them would attack it at all, and those that did went at it singly and with a certain hesitation, and so each in turn was disabled by a single terrible snap, and left bleeding on the snow.

General Wade Hampton tells me that in the course of his fifty years' hunting with horse and hound in Mississippi, he has on several occasions tried his pack of fox-hounds (southern deer-hounds) after a wolf.
