I'm not a big fan of a lot of things TSA has done, but I don't see any big issue with that video. It's just explaining what will happen at the airport for kids to help keep kids from being too nervous about the airport. Most adults know it's no big deal at the airport, but kids worry about a lot more. As far as the dogs-the TSA agent was also one. They probably used dogs instead of people because kids react well to animals.
