Why does my dog growl when she sees animals on the TV?

I have 2 dogs. One of them goes crazy when she sees other dogs and animals on the TV. This is really strange. She'll run up to the TV and start barking and growling. She'll even claw the tv. I have never seen a dog do this before and my other dog doesn't. I didn't think dogs could see like we do I always thought they went by their scent. Is this normal? Does anyone have a dog that does the same thing?
