Hi! Heelers are great "people". At my grandparents' house we have 4 of them, 3 red and 1 blue. They are very intelligent and VERY amusing. They don't get to be very big. A medium size breed no bigger than an American Cocker Spaniel. They are very good with children if taught at an early age, so be thankful your Zoey is still a puppadog! After all they are "heelers" and were bred to nip, if they aren't given anything to herd they may take a whirl with kids! But they are generally great with kids, all of ours are. Well, good luck with the "child" rearing! Post lots of pics!
