I don't know what to think about that. All three of my dogs would not have followed someone to Chicago even for food. In fact, both of my shepherds don't/didn't even take treats from others half the time. Rocket is the worst for accepting treats from strangers or people he doesn't know, and it's kind of embarrassing at the pet store, heh.
I know that everyone in my household loves him, they have all spent time "training" him and the kids and DH feed him half the time, so why does he follow me and lay with me almost exclusively? Even when I'm working and gone 60 hours a week? Why doesn't he start following DH who spends the majority of the day with him then?
Interesting article. I'll be curious to see what others have to say.
