For all of you interested in dog behavior, my husband found this awesome English TV special that followed dozens of dogs and recorded their behavior while their owners were away. It focuses on separation anxiety and how to alleviate it in your dog. It's not all about Sibes, but nonetheless, as someone who's always wanting to learn more about dog behavior and training, I found it incredibly interesting.
There is a follow-up to this special as well that was just released this month that we have in the queue but haven't watched yet.
