I should wait for those who have first hand experience with this, but an article in a magazine some years ago reported a wolf pack attack on hunting dogs in a Western state. The dogs were injured and one was left with gut exposed. One of the hunters was an ex Army medic and observed that the dog would recover and that he had treated worse wounds in combat. Other dogs had bites and bloody wounds. The dogs were shocked by the attack and the hunters were alarmed at a threat to themselves. The story made me think about how things have changed with the reintroduction of wolves, mountain lions, and the spread of the less dangerous coyotes everywhere. Our pioneer ancestors must be shaking their heads.
In the past I worried only about bears and rattlesnakes.
