(In case you are interested, many of these are calming behaviors meant to calm both the dog himself and the owner. The behavior context is that the owner just came home from being away at work. The dog could also be offering the behaviors in response to seeing the video camera.)

2. Dog Doing Nothing-Golden Retriever

So, what did you learn from watching the dogs behaviors in these videos?

Hopefully, that dogs offer many clickable behaviors all day long. We trainers just have to improve our observation skills and our clicker timing to be able to capture them to use them to shape behaviors we desire!
