That kind of attitude is what led to a rash of badly bred, ill tempered Chows, imo. Aloofness is one thing, being unapproachable is another thing altogether. While, were a stranger to approach me in a threatening manner I'm sure there'd be issue, both of my Chows are more than happy to either sit by my side calmly, or greet a neutral person with butt wiggles. When looking for a Chow pup to join my family, I searched for a breeder who had family dogs, did health testing, and focused on temperament. I got a pup who fit our household perfectly. At 7 months, he's still a splendid example of what I was looking for.
