I think it really depends on the puppy. We had our hearts set on a female but we took one look at Rowdy and our hearts melted. We picked him up and he licked our faces. We held him like a baby (on his back) and he just looked up at us with those sweet eyes and it was all over.
I do think he is more attached to me that to his daddy (with whom he is with all day long - I work, he doesn't). But I would say that he is most happy when his daddy and I sit on the couch and he can sit between us!
He is 10 months old, not yet neutered, he lifts his leg to pee, but he doesn't mark in the house.
My advice is to go with your heart!
