When we think of dog doors, we think of flaps that allow dogs to trot on through. What a great convenience this can be for you and your pet. Allowing your pet this extra freedom can be exciting and it saves you the time of getting up and opening the door six times a day! But, we live in a modern world with great inventions. One such invention involves our dog door! Pet owners can now choose a dog door that is electronic!
Back in the day, a dog door was a simple flap. Often flimsy and thin, so the animal could pass through, it made keeping a home warm in the winter a tad harder. Or, it helped the air conditioning seep right out into the backyard. Kind of reminds you of that saying your mother used to use.
