Their temperament can vary greatly, depending on whether they're well bred or not. Goose is our third Chow (our elderly male passed on a few years ago and we have a two year old male, Aesop) and all have come from good breeders, so have all had great temperaments. They're a very stoic breed, can be a bit aloof. Very much an "I know you want me to do such and such, but could you explain why first?" kind of dog

Many call them one person dogs..but that hasn't been the case with any of mine, so I tend to question that. Mine tend to love everyone

Of course, I do socialize them the same as I would any pup. They're not too high energy.
I find them a very enjoyable breed, even if it does mean I have to hear "your dogs are nice, but I knew a Chow that did such and such" stories all the time.
