This is Kosmo. He is a 2.5 year old Blue Merle. He is a high energy dog who loves to play frisbee! He is good with close family but takes a little with those he is not familiar with. He can be very protective and postures aggressively. He is not formally trained and he is not neutered. If there was ever a working dog, Kosmo would be it. When I am away he becomes dominant. I cannot give Kosmo the time that he deserves or the open space that he needs. A ranch environment with livestock is ideal or if in a suburban setting, an owner who is very active/outdoorsy. We love Kosmo but we are not a good fit. Please help us find a good home for Kosmo.
