Skyping dogs

In this video, two dogs appear to be skyping with each other, while one of their guardians looks on. There's no context or explanation as to whether the dogs know each other or are strangers, but it certainly appears as if they are having a somewhat mournful conversation with long lost loved ones. The video can serve as a good entry point for a discussion about whether, first, dogs can recognize each other through the medium of a computer, and second, whether and how they can communicate through it.
