Darcey; A good dog would jump out of the way without being asked. They aren't human children. There could be a problem if the dog starts to see itself as a pack leader instead of a subordinate. It's up to you, But I would advise that you keep it in its place. It could be difficult later on if it gets its own way. It's your judgment. There's probably lots of doggy people here who could add useful comments.
We had a very domineering ***, who needed strong leadership and who never stopped pushing towards the top of the pack with us; but she settled in to treat us as a pack who needed her love and protection, and fortunately she was not innately aggressive, just strong-willed. She would have died for us if necessary, and when she eventually did go, she was a darling grumpy old granny who loved us all.
