For the task of killing an animal with a knife, you can weaken the target first (especially handy with bears) using gunfire before finishing the task with a knife.

If you are by yourself and do not have a partner to back you up with a firearm, you can try shooting a bear in its head with the Henry-Martini repeating rifle and one knife stab should kill the target.

There are a total of 94 locations in the game. 45 are in New Austin, 32 are in Mexico, and 17 are in West Elizabeth. The quickest and easiest way to find these locations are through the maps you can purchase at various general stores. These will unlock all areas in a specific part of the game.
