My dog is the coolest because...
If he fits he sits. Sometimes finds the most awkward strange places to fit. Bathroom cabinet, small perch, top of moving boxes, bags, laundry basket, or whatever. He first needs to see if its a place he fits. If so, then he sits (laps are his favorite).

Peacemaker. Doesn't matter if its dogs or humans, he's there to keep the peace.

Singer. Loves a good family howl. Whether its a birthday song or just a random moment, he sees someone singing / howling, he's in.
