YELLOW URKA-GURKAS
Dog runs around the house and hides under furniture while making a prolonged “uuuurka-guuurka, uuurka-guuurka” noise. (This noise is the only thing guaranteed to wake up a true dog lover who is hung-over from a post dog show celebration at 3:30 am.) After mad scrambling to capture the dog and drag him outside the episode ends with an indelible ten yard line of slimy yellow froth from living room rug to back door.
BLAP DISEASE
Dog exercises hard and a) eats large mouthfuls of snow (Winter Blap Disease), or, b) drinks a bucket of water (Summer Blap Disease). Within 2 minutes of returning inside the dog spews out large amounts of clear slimy liquid while making a distinctive 'blap' sound and sharp percussive noise as it hits the linoleum.
GARKS
Dog suddenly clears his throat with loud and dramatic 'gggaark, gggark,' noises, generally followed by prolonged 'iiikssss' and then loud satisfied smacking noises. There is nothing on the rug. Don't investigate. You don't want to know.
RALFS
Apropos of nothing, the dog strolls into the dining room and waits 'til the innocent dinner guests are all watching him. Then with a single deep gut-wrenching 'raaaalfff' disgorges the entire week's contents of his stomach on the dining room rug.
VARIATION:
then he eats it.
