Dogs and TV

I've realized I can't have the "Dog Whisperer" on while i'm working at my computer if the dogs are inside. The barking freaks them out and gets them into a tizzy. Today while eating my sandwich for lunch I turned on the tv. "Marley and Me" had just started and although I don't want to watch the entire thing I kept it on. One scene the puppy is running down the beach. The dogs had been watching it since they heard the whimpering. Maggie watched the puppy run across the screen and then when the puppy left the screen she went around the corner to look for him. Needless to say, she was confused.
