Cavalier King Charles Spaniel. You'd need to go with a reputable breeder (of course) and see evidence of testing because they've really suffered from breed standards.
I disagree with labs and goldens - they're a dog I always steer clear of at the park. They come in just under rotties for aggressive bites (having said that I'm more of a 'deed, not breed' person - but I thought I'd throw it out there).
...the last statistics I read had Daschunds, Chihuauas, Beagles, and JRTs at the top of the aggressiveness/bites scale. Goldens are under Rotties, yes, but near the bottom of those charts! xD (A mirror of the original article can be found here: http://indigorescue.org/?page_id=83)
I agree with the "any dog looks friendlier with a colorful bandana" rule! And I like most dogs, but I squeal and go all and gooey over Goldens (of course!), Great Danes, Boxers, Rotties, Bermies, and Collies. Dogs (usually under 20 lbs) that yap aggressively and jerk on their owner's leash get entirely ignored and then badmouthed once I'm out of earshot. >.> In my experience, people spend more time training larger dogs (because it's a lot more annoying if they yap/jump), so they're frequently better-behaved.
I see the OP has chosen her breed but wanted to throw my $0.02 in anyway! =D
