My fav are mutts that have some german shepard in em
But I was at the pet store this week and it was adoption day, and this one dog there... holy shit I almost got him cause I could tell he was special. Dude was probably ~4-5 months old. Looked like he would grow to a medium size. Was a mutt, colored with brown and dark brown markings like a cross between coyote and shepard.
But damn, this dog wasn't in a cage. It was laying on a little towel and just chillin. But it was alert. Dude was tracking people as they walked by, just watching and paying attention. But he never got excited and never got up. With all the caged dogs barking and people walking by with their own dogs on leashes... dude just chilled like no big deal. And he wasn't oblivious. Like I said, was very calm, but still aware of what was going on around him. Too bad I travel around too much cause I woulda brought him home. It was obvious he was a special dog.
