An easy and humane method for dispatching small animals is to lay the animal flat on the ground and gently pin it by the neck with a pole (a rake handle will do) with the head facing straight forward. Then quickly step on either side of the pole, grab the hindquarters of the animal and yank the body up and over the pole. Breaks the neck, severs the spinal cord and they die very fast with little pain.
There are few things more satisfying than whacking another living creature across the back of the head with a shovel with all your might until it stops twitching.
I’d give the puppy a fighting chance. Five minutes in a cage with an 8-year-old chimp starved for two days and forced into the cage with an electric prod. Evil enough?
ETA: I just went to Skald’s original thread and clicked on the pic of what a schipperke puppy looks like. I… CAN’T… DO IT!!! OK, maybe a one armed starved chimp.
Possibly it might die of embarrassment, first, though, what with the doggy cosplay we will engage in first. Although it’s not leggy enough for an AT-AT suit, it has the right looks for the Ewok costume!
