Is this common for dogs?

In MY opinion, any dog that puts its paws on an owner shoulders is, in dog language acting dominant and disrespectful. I NEVER allow my dog to put his paws on me OR jump up at me.

Of course it all depends on the dogs genetic temperament but its not usual for a submissive natured dog to `dare` to put its paws high up on its owner.

Plus of course....what it means, can be interpreted in the way that the dogs owner WANTS it to be interpreted as, and not what it really means. 

Lots of owners tend to anthropomorphise a dog and see what they want to see especially if it mimics a human action.

So....Believe what you want, it`s your choice.

you should put it on youtube

depends on the dog, theyre all different

My Dalmatian did this all the time. Many dogs do this, for comfort. 

It's relatively normal.  Dogs are known for seeing a human do something, and then doing the same thing as best they can.  Look up "dogs who sit like humans" and "dogs who smile".
