Easy way to find your targets at night time

Equip your dog (make sure the DLC/companion is active).

Press B to open the pet command wheel/list.

Move your mouse cursor over the “Point a target” (or similar) option in the wheel.

Right-click while hovering that option to open the size submenu.

Choose Small, Medium, or Large depending on the animal you want to mark.

Your dog will begin searching for that size — watch its movement and follow.

Follow the dog quietly. Animals don’t run from the dog itself — but if you move too much, you’ll spook them. Close in slowly until you’re in range.

Find a best spot in rage to take down your target.

Enjoy... don't forget to give a cokie to your dog. :)
