The Mafia Dog

Malvina´s parents were rich but they only allowed her to have one dog although she´d love to have ten.
Her dog was a Labrador. Malvina got him as a present from a man on the street. He was dressed normally and he said he didn´t want him. So Malvina took the dog. At home her parents didn´t agree to keep him. They said she shouldn´t talk to strangers and certainly she shouldn´t take things from them, but Malvina still wanted to keep him.
Malvina took the Labrador to the vet, who examined him and said he´s in perfect condition.
After lots of persuading Malvina convinced her parents. Now he was hers!

Today was a sunny day, so Malvina decided to go to the park with her labrador, Choco.
They were playing frisbee when one of her classmates (NateJ) came over.
“Hey Malvina!“ he said.
“Hi Nate!“she said.
They started playing. Malvina threw the disc. The wind was blowing, so the frisbee flew to the left hiting a tree. Choco was running after it, his tail wagging. As he ran past the tree, his tail hit it. It fell off!!!
Suddenly Choco´s whole body froze and he hit the floor.
Nate and Malvina just stared.
In a few seconds, lots of men came rushing up to them and tied them up. “W...Whats happening?“ Malvina asked.
“Hi Malvina“ a muscly man who seemed to be familiar said.(How did he know her name?!)
“We know everything about you. Now you´ll just give me all your money and we´ll set you, your frind and your robotic dog free.“ He said.
“What? Robotic dog? Who?... oh! Your the man who gave Choco to me arn´t you? And he´s robotic! But why!?“ Malvina said. She didn´t understand.
“ Well, I see that your a bright kid! Exactly! I gave you the dog. He isn´t a real dog. He´s a spy. He had a microphone on the tip of his tail so we could hear what you and your family were talking about. Now we know everything we need to. It was about time he hit his tail on something and it fell off. See everything was based in his tail. I thought I´d give up in a few days but no everythings alright.“ The man chuckled.“ I´ll just call your parents and they´ll pay me to let you go.“ The man laughed.
“May I just say goodbye to Choco?“Malvina begged. She had a plan.
“ Okay! It won´t do any harm. But guard them!“ Good, Malvina though.
She came over to the frozen body of her dog. “Could you please loosen my rope so I can stroke him?“ Malvina asked in her sweetest voice.
“´kay“ one of the guards said. He loosened her rope.
Malvina strocked the Labradors´ coat. Then she picked up the tail and pretended to look very sad. In her head she was going over her plan. She hoped it would work.
