You know you love your puppy when: you hold him in your lap and hold whatever he is chewing on so he does not have to.
you dry his paws and legs off every morning after his walk so he does not get cold when he comes in the house.
you end a phone conversation just because he is sitting there barking wanting your full attention.
you take him to pet daycare twice a week so that he can have fun with the other puppies
and all of the other wonderful things all of you have mentioned already.
