Anything for money huh, you know what let's take this experiment a step further to really separate the psychos...
He should offer $500-$1000 just to buy the dog. Broke boy amount of money.
$100,000 to buy the dog and tells the owner he's buying it to kill it in the most inhumane way possible.
$200,000 to buy the dog and tells the owner he's buying it to kill it in the most inhumane way possible but the owner has to watch it.
$300,000 to buy the dog and the owner has to put a baseball bat in his/her hands and beat it to death themselves.
I mean surely you guys are down for the max amount right since dogs are soulless creatures you could give two fukks about?
