I definitely believe that the pack mentality holds true with these dogs every bit as much as any dog. I have and currently let my dogs interact. What is interesting is that for the most part they get along. Not always but for the most part. Any "ousiders" though take some time to allow in and other dogs outside the pack are not welcome. I just think it's all about the owner or the pack leader if you will. I am sure that this will not work with some dogs. No way. The other thing I have noticed is, and I'm not sure why but I have a female that seems for the most part to be the alpha. Now I know that she would get her ass kicked if it came down to it but I think her pussy plays a part in this behavior. Lol
