Like Barb, I don't really think they exhibit totally human behavior, but Shelties are CONSUMATE communicators! You might say they speak fluent human.
Both my Shelties (and my border collies to a lesser extent) have communicated to me with subtle eye movements. All I have to say is "tell me what you want" and watch the eyes. They'll go from you to the item and back again. I like to mess with their heads by mimicking the eye movements. Drives Bela crazy, but she's learned that all-important, successful indoor dog skill, how to communicate effectively with her human.
Helps, too, that I "speak dog". Bela and I tend to be pretty tuned-in to each other due to the fact that she and I are together better than 90% of the time. She still has the occasional "feral dog" episode, but is getting better and better at refocusing herself.
That being said, she does LOVE to watch TV. I mean really watching the screen. She was fascinated with it from day one. Since she was a puppy mill rescue, I figure she'd never seen one before, and it just caught her fancy. All I really know for sure is that this is the bravest and most joyful little dog I've ever had the pleasure of sharing my life with!
