The Snore

A thief enters a house at night to hear a loud snore that vibrates everything, so the thief hits the ground.
He thinks to himself about the noise that he heard as he looks around.
Oh my, Oh me. Could there be a bear in the house with me?
I falter to hold my gasp back because I can only imagine what it could be?
Did the home owner decide to stay home and not go out as planned?
Am I going to get caught sneaking in and find myself being canned?
Is there a heavy set person slumbering away in the room I am in?
Should I have taken more precautions and started in another room like the den?
To my surprise I find that no one is home at all.
But, I see laying on a rug in the middle of the hall
A giant shape that is indeterminable from my angle
Oh my, oh me. Maybe it is a bear that I will entangle.
No, it's not a bear after all that I see.
It's a 300 pound Rottweiler looking straight at me!
