From what I read on the site Natalie gave me, all the things they listed are traits found in almost ALL primitive breeds of dog and I feel they aren't so much 'negative' but bluntly truthful. These ARE things one should be aware of if you bring a primitive breed of dog into your home. They aren't like other dogs--they have many natural instincts that are still intact and so handling and rearing them should be approached a little differently.
FYI--Kirby is a Samoyed, another primitive breed, and I identified with MANY things on those lists. If you don't work extensively with the dog to be used to being around children and small animals, they can very likely have a tendency to be snappish to small, yappy things or small things that run. Socialise, socialise, socialise.
Also, food aggression is another tendency. Even Kirby sometimes has bits of it cropping up still. With breeds of dogs like this, you HAVE to estabilish yourself as alpha to them. Keep in mind the dog will always love you, but you have to PROVE that he should respect you as well and accept your authority as alpha of the 'pack.'
I feel that when dealing with breeds like this, not only should you research the breed, but also research how wolves behave in the wild. Learn how they talk, assert dominance, etc. Learn the importance of eye contanct--if you're ever in a staring contest, DO NOT look away. It says you're submitting to the dog.
Sorry if I sound a bit unconventional, but it's something I believe in concerning primitive dogs. With such intelligent, wild doggies as these, you have to think outside the box.
