Killing a animal over 50lbs. by hand is no small feat. Big cats are scary fast and pointy. With canis, you give a forearm, twist the dog to side, and crush the ribcage with body weight through the knee.
Anything big is good for 10 sutures per pound over 50lbs.
I have a friend in mountain lion country. He says even a pistol is of little use. You only know they are there when they are on you.
