Chows I don’t know scare me. I’ll admit it. And I moonlight in the working dog crowd (they need someone to run the camcorder after all), so I’m not scared of big dogs. I think I am smart to be wary, but you can correct me if I’m wrong!
You can’t make generalizations about an entire breed, except that as a whole they lean one direction or the other. I have a female doberman who can’t fathom biting a person and she has good (annoying) drive, but was trained to be the family pet.
I have a male doberman rescue who has a hair above zero working drive and NO protection mentality period that would bite, but he is the most laid back, not nervous, cool dog (except when he’s sleeping). He had a rough beginning. My point being it is the upbringing, with the exception of certain breeds, more than anything.
I have been threatened by a couple male labs in my life. Aren’t labs supposed to be the poster child of “good” family dogs…
The only dog that has actually bit me was a friend’s dad’s hunting spaniel. Totally out of the blue when I was a kid and left alone in the house with him for a few minutes (I think I had to go). I have had and known various spaniels (cocker, water spaniel, etc.) who got very nippy with strangers, particularly in their old age. I think it was (irrational in their case) fear more than anything, but their senses were weakening and that’s what they turned to.
