I personally look for the one that gets out and explores. I like independence. I don't want one that is shy but not one under ur feet wanting attention I want the one that just does not care about u and is doing its own thing if u pat it it is happy but if u stop it is off exploring. I do NOT want one that cowers though.
x2...but I like picking pups from my own back yard the best, this way I can watch them every day and do some checks on them.
