Mine is the one in grey. I saw him get macho to some very big dogs next door. So he has embraced the Klingon spirit. I'm looking for a unique name ideas. Maybe something in Klingon or Vulcan. His personality is such that he would punish me for things he doesn't like. His breed is known for intelligence and often used for cattle herding. Very strong jaws and sharp teeth. For me he will be a family pet/guard dog. His breeds nature is to be very protective of his owners things.
