Anything with a laid back personality is great with kids in my opinion.. I have a five yr old and we own a saint bernard, she is AMAZING with kids..
But she's huge... it depends on the size of dog you want, and energy level... Things are always more complicated then just 'liking kids'..
Iv'e noticed Shih tzus are awesome with kids, pugs, basset hounds, german shepherds, siberian huskies, elk hounds, keeshunds, beagles, goldens, cocker spaniels, springers... theres a few :-)
