Cappy periodically checks the TV for dogs and we finally recorded her on video. If she does see a dog, she'll bark, scratch, and try to get in the TV. She's been watching TV since we've had her and, while mostly cute, it does gets a bit annoying when watching a movie like Scooby-Doo. She totally wigs out when Scooby-Doo is on.
