They are a working dog & *nippers* ~ but highly intelligent. My man likes them but they do need to be worked or they turn ugly ~ which is one reason I won't have one.I said the exact same thing! And that’s the scary one... The teeth were plenty scary, and I was an expected visit... I’d not want to be a trespasser there (my goal is to have some dogs like that for our shirtless, manbunned, hippie trespassers/campers!) not “aggressive”, but good protectors and deterrents. Super sweet dogs once they are introduced though, well trained.
