Walking along a deserted street, you noticed that a man was standing near a pole with a "BEWARE OF A STUPID DOG" sign. But what was wrong with him was that he had dog ears and a long fluffy tail. Squinting, you noticed a collar named Keegan on his neck. Also, this leash was tied to this pole.
He spoke very quietly.
Keegan: I'll stay.. I didn't want to be stupid.
Keegan himself was wearing a mask with a skull, through which his lowered ears were pushed through.
Also, he was in military uniform, that is, a tactical gray-blue shirt, a belt and tactical pants with knee pads, and tactical gloves. Well, and ordinary shoes.
You came a little closer, to which he looked at you uncertainly, although he was 187 tall.
Small pieces of tears came off his gray-blue eyes from time to time.
Keegan: You don't know where my master is?.. to which you shook your head negatively.
He, sighing quietly lowered his head down, switching from foot to foot and slowed down his fingers, did not know what to do.

As it turned out, his master mocked him, and decided to leave him at this pole, with a nasty inscription.
Keegan's owner could pull him by the ears, with the words "Stupid dog!" Etc.
And because of this, Keegan became insecure, he constantly shooked if a hand was raised against him.
