I've been thinking about this for a while.... I have always been greeted like a member of the family that has been gone a very long time by my mother's dogs, even though I haven't lived at home for a number of years and before that I was only home during uni holidays. Both my mother's current dogs were brought up without me in the house. I came home twice during Pyry's puppyhood, for maybe a week each time, and once during Jill's puppyhood for only a few days. Yet, whenever I come home I get bombarded with delighted kisses and both dogs will try their best to climb into my lap for cuddles. They only do it that first time I come home, and then if I'm staying for a bit, they treat me like they would any other member of the family, with much more normal greetings from then on.
At first I thought they just liked me because all dogs like me, but then it slowly occurred to me that the greetings I was getting when I came home were the kind that only family members get when they've been away overnight or longer. I have an older brother who comes home less often and I'm told he gets greeted with gusto as well, although not quite as much gusto as I do. My theory is that because both of us lived at home for all the years it took us to grow up, our smell still lingers on things around the house and the dogs assume that means we're part of the pack as well, even though we're rarely there. Another possibility is they respond to the way the rest of the resident pack greet us. But I've seen them be much more leery of visiting family that hasn't lived here in the house.
Thoughts, people? Has anyone else noticed something similar in their packs?
