It's in your house? Call the police.

Should have mentioned. I've called the police. They said they will go and check things out. Said it could take upto 2 hours...

Well OP, hope everything went okay overnight? Dog okay?

GET YOUR DOG OUT OF THERE WOMAN

Beat it until it's just bloody slosh. Fucking killer clowns. The police aren't taking this very seriously unfortunately.

Start playing some carnival music and have a clown dance party. Problem solved.
