I have been told by my trainer to always treat Sam first before Lucy and ensure Sam that he is higher up in the pack and I have done that. But I picked up a book someone recommended on here called "Feeling Outnumbered" and it talks about how as the pack leader, you should let them know there is no #2 position available and once that is established then there is no competition for position and they are happy just all being on the same rank. I was wondering what others thought of this...
