Why does my younger dog stand still in front of the older one when she is lying down He gets right in front of her mouth with his ear and neck?

Answer 1

He is showing that she is the dominant dog. One way that you, as the master, can assert your dominance, if that is an issue, is to have the dog laying on its side and then lay your neck (adams apple area) across the side of the dogs neck. You may want to hold the dogs snout for safety the first time you do it. This tells the dog that you are in charge. But, to answer your question, it is to show dominance. Dogs are pack animals with a hierarchy.
