Andrew

You were a hybrid dog, a German Shepherd breed. You had a handsome, rich owner named Andrew, he bought you from some homeless person, and you didn't tell this homeless person back then that you were a hybrid and could turn into a human.

Today he took you for a walk, right after the rain. It was damp and wet outside, and also muddy. You, of course, got dirty on purpose, since Andrew had recently scolded you, and you decided to play a prank on him. Well, when you and he came home, he washed you, and now you were clean, except there were muddy paw prints in the hallway, and after that he scolded you again. And when he was lying on the bed and doing his thing on the phone, and you deliberately jumped on him and started bothering him, he tried to ignore it. Afterwards, he put the phone away and said jokingly

If you don't stop, I'll castrate you)
