One thing I'd love to see, saw it a long time ago on either America's Funniest Videos or Pet Star. I think it was a Doberman who got up on its hind legs, opened a fridge, got a beer, brought it to the owner, then when he was done she would recycle it. That was awesome.
Here is a clip with a border collie getting a beer:
Dog Gets A Beer
Another one I'd like I heard about from my sister's boyfriend. He went to a client one day who had a harlequin great dane in her office. She'd go "Ok Bowzer, you ready?" And he'd go sit down, she'd pretend to pull out two guns out of her pocket, and she'd go "Bam, Bam" and he'd slowly lay down, turn on his back, legs up and play dead. Loved the story, would have loved to see it.
Also love the ones where dogs balance the treats on their nose, and when you say ok flip it up in the air and eat it. I'm sure dogs on here do it.
I still love the paper trick, too. Got to get one of mine to do that!
