Our Pack, Inc. in San Francisco has been mentioned here numerous times. They have done wonders for rehabilitating the image of the pit bull, first by rescuing them (a la the recent largest-ever dog-fighting bust in Missouri), and then by loving their dogs, insisting on good behavior, and providing a safe and fun home. Then they share the goods. Enjoy!
These two videos feature at least one Missouri dog fighting raid dog that was rescued. Amazing.
This one below is really something. My dachshund-chihuahua pound puppy isn't this nice. Neither is Mom's yorkie, George. Definately not!
