Do you know the common saying that the bigger the dog, the more lovable they actually are? I don't buy that bullshit anymore. Meet Fenrir:

Yeah, I see that dog and I'm not thinking "big cuddly thing." I'm thinking: "where the fuck is my body armor?!"

From Wikipedia:

"Take care to ask the owner before touching as these dogs are not 'big teddy bears' to be run up to and cuddled."

No shit?
