I have been here too, although not quite the same. My oldest Max (who sadly is no longer with us) was a real Mummies boy. Although he loved my husband too. Levi who is 9.5 is a Daddies boy, although he is very affectionate to me too.
My new puppy Teddy who is almost 9 weeks will be a Mummies Boy we feel.
When Max was with us, he would put himself in between us if we went to have a cuddle. Many would say it is wrong and we should of trained him out of it.
BUT we always included him in all cuddles, He would do what we said and was eager to please. But if someone took my attention for too long, he would start making little noises to remind me he was there, and was watching.
I guess it depends on what you want in the future. There are some great people on the forum that can offer good advice on how to deal with this.
