You may have heard the myth that when a dog sits or lies on top of your feet that he is trying to dominate you. But nothing could be further from the truth. Many dogs form a strong bond with their owners. Wherever the owner goes, the dog follows.
Scratching the Bed Is a Natural Instinct
This is typically a natural instinct. Your pup's ancestors often scratched at leaves and dirt in the wild to create a makeshift bed for sleeping.
Due to your role as the leader, your dog knows that you get to have the best area for comfortability that there is.
