Dogs are fun and loving creatures, but at the same time they can display some behavior that may seem odd to you. You might have often seen your pet sleeping or sitting by the door. Well, there are some reasons for this strange behavior.
Waiting for You
Dogs have a strong emotional attachment with their owners. Some of them would try to follow you everywhere, even in the bathroom as well.
If your dog sleeps by the door, it might mean that your pet eagerly waits for you to come home from work. Once you arrive, you might have noticed dogs constantly wagging their tails in excitement and happiness. Many dogs also jump on their owners and lick their faces as if they were separated for years.
You can use a dog door to let your canine buddy know that you are nowhere near the house.
