Dogs have always been man's best friend, especially for meeting women. Nothing screams "sensitive guy" than a dude with a puppy. But which breed is most effective at picking up chicks?

Thanks to the Puppy Pulling Power experiment, we now know. Five types of dogs - a Samoyed, a Pug, a Border Collie, a Staffy, and a Yorkie - were outfitted with a Sony Ericsson C510 camera phone what has something called smile detection software. Whenever a woman came up to admire the dog and smiled, the camera automatically snapped a photo.

Here's a video (containing lots of cleavage shots because the dog as a great angle) that sets up the experiment:

Now you should note that this "experiment" was sponsored by Sony Ericsson and is a blatant promotion for the camera, so who knows if the results are valid? But, according to a helpful graph on the Puppy Pulling Power website, the Samoyed wins:

So guys, when thinking about your next dog, remember: big and fluffy gets the chicks. You can check out more photos of the girls in the experiment and their, um, nice angles, here.
