I have...a GSD, and then mixes:
F BC-Chow +? mix
F Chow-Spitz ? mix
F GSD mix
F Chow-Terv ? mix
M GSD-Lab ? mix (maybe some Chow and/or Rottie in there)
M GSD-BC ? mix (maybe some northern breed in there)
M Sheltie-Corgi (?) mix
I have a foster that is a 1.5 yo Lab/BC mix (?)
So there are similarities - either in the herding breed or Chow type breeds. So they all have similar rules and types of behavior. They were also "admitted" into the pack based on a majority rule, based on how they could add to the group, and assimilate. Some needed to be here...or else, so luckily, that is the kind of dog who is admitted into Jeanspackistan.
Things are given in order of seniority, and they so far, are okay with that (no prison riots).
I had a strong alpha, true alpha - the larger black/tan dog (Kramer) in my avatar. The smaller black/tan (Bruno) moved into and shared that with my GSD Bella, who is not a natural alpha and does not want to be an alpha, but she is a Queen Bee, and that works. I have more work to do in terms of leadership, and could never do it as well as Kramer, but I am trying.
