Udderly delicious!

I was reading John Stossel's new book and he had a blurb about dog food companies. Stossel says that expensive dog food is not better for your dog. He said that the secret ingredient of dog food is cow udders. Dogs love the smelly parts of animals, such as, the lungs and udders. Stossel's experts say that they have to monkey around with the ingredient ratios so that pet owners are not offended by the smell of the dog food, but that dogs prefer the stinky food, paws down. I know this to be true. My dog once dragged me over a cliff to roll in a dead stingray!
