Dogs, by their very nature, are very protective. They watch over the members of their family, their pack, and their home region.
If your dog is watching out for you, it's probably because he or she considers you to be a member of the pack.
They are able to keep an eye on you even when they are laying on top of you.
They feel more secure when they are aware that you also have security.
Your dog's strong sense of duty and unwavering devotion give them the impression that they are responsible for the health and happiness of the individuals they care about the most
It is not necessary for you to be concerned if your dog is acting as a guard for you as long as it does not become excessively protective
