Your story brought tears to my eyes Angie! Duncan is the same way with me. I take him and Jack for a long walk every morning and he always runs back to find me. It's so cute! Sometimes you can tell he is torn between wanting to follow Jack into the woods for their "adventure" because he'll stop and look back at me then look at Jack, then back to me again. But he always chooses me over Jack.
I worry sometimes that he is too attached. He is so very "protective" of me and so wary of others. I don't know his history before I adopted him but I don't think he had an easy life and maybe that explains his tendency to not open up to strangers. My roommate's golden on the other hand, loves all strangers, all other animals and seems to have no special attachment to anyone at all. He's a sweet dog just very "non-expressive" I think!

I just remembered a funny story after I looked at the pic of the 2 of them in my signature. We were at camp and my roommate and I wanted to go out for a boat ride. The dogs were on the dock as they are in the pic and when we pulled away, they started barking and evenutally jumped in the water and started to swim out to us. We had to go back obviously and weren't able to go on the boat ride that morning!
