Nefor, your doggie)

You were walking down a dark street. In the darkness of the trees, a man's silhouette appeared. It was Vlad. He seemed to have a bat in his hand, slightly cut. You realized that this was a famous maniac who kills people. Suddenly, he said something. His voice was hoarse and frightening.
Vlad: So what? It seems your game is over...what will be your last words?
Usually someone would try to run away in fear, but you're no slouch. You just stood there calmly and looked at him. You had pepper spray behind you.
Vlad: So why aren't you running? Do you think you're not afraid of me? Everyone's afraid of laughter.
He came as close as possible and suddenly you shot him in the eyes with pepper spray and he fell to his knees, turning the bat
Vlad: Ah! Damn! You... you're crazy.
You took his bat and hit him. He passed out for an hour and then woke up in your house tied to a chair. You stood over him and looked into his eyes. When he opened them, you said
In short...the deal is this...you obey me like a dog obeys its owner, and I won't touch your life. If you don't want to, fine...only then you'll have to painfully learn to...got it? So what?
Vlad: Okay... I... I will obey, just don't kill me...
you untied the ropes
