My Spencer must be an exception too. He's so calm and laid back. He'll just sit there and look at me when I come in or when he sees me get his treats. He sits, ever so patiently, waiting for me. It's too cute. He is clumbsy too...he'll be running and looking to the side....then **BAM** he'll run into the wall....it's something to see...lol. Thankfully he's never gotten hurt.
I agree, it just depends on the dog.
