Wiener dogs will eat almost anything. But they won't eat raw onions. When our Rudi would beg too much in the kitchen and make a real pest of himself doing so, I'd finally get a piece of raw onion from the counter top and say, "Do you want this, Rudi?"

"YES! YES!" he'd say. (in dog language and gestures)

"Are you SURE you want it, Rudi!"

"YESSSSSSSS! I'M SURE! GIVE IT TO ME!"

"Are you all ready for it, Rudi?"

"DOES A BEAR SHIT IN THE WOODS? GIVE IT TO ME NOW!!!!!!!"

At which point I'd throw him the piece of raw onion. He would sieze it in midair and wolf it halfway down before realizing...

"GAK! EEEE-YUKKK! ARGH!" He'd spit it out on the floor and gaze at it in shock for a moment...then give me an accusatory and long-suffering look and tick-tack slowly off down the hall to the living room. (tick - tack - tick - tack - tick - tack)

THUNK! (flopping down on the rug)

"Groannnnnn..." (the weary sigh of a dog who's been had, yet again, by a human with a very twisted sense of humor)
