Why does my dog choose to lay on my neck instead of other places?

Dogs often choose to lay on their owner's neck because it provides them with a sense of security and closeness. The neck is a warm and comforting spot for them to be close to you, as it is a central and familiar part of your body. Additionally, dogs have a natural instinct to seek out areas of their owner's body that emit the most scent, as it helps them feel connected and bonded to you.
