Dog vs. Oven Fan

Does your dog tremble at the sound of the oven fan? Mine does, and it is all because I'm lazy and don't clean out the oven. With each use of the oven there is a nice blare of the smoke detector to go with it. Especially when making Polenta because that stuff is baked at 500 degrees! So, I wait...Peanut trembles...as we anticipate the horn.
