The German Shepherd (also called the Alsatian) is part of the herding dog category. They have a handsome wolf-like appearance. The breed is believed to have first originated in the late 1800s. Protecting and herding sheep is the purpose they were initially raised for. In the modern day they're a common choice as a family pet, movie roles, police dogs or for search and rescue. Features such as their high intelligence, dependability and courage are things they can be identified by. They are a descendant of a mixture of German farm dogs and are thought to originate from Germany.

They are categorized as a large sized breed of dog. The appropriate male size is 24-26 inches high and a weight of 75-95 pounds, while the female size is 22-24 inches high and a weight of 60-70 pounds. Their character is famously known to be fearless and protective. They're mostly suspicious with people they haven't met, and this can make them highly suitable as a guard dog. In comparison with every other dog, they are identified as being highly intelligent, and rank 3rd when being trained to learn new obedience instructions.

They are great towards children, and that means they are very suitable as a family pet. Other pets such as other dogs and cats they're raised with do combine well with them. Looking after their coat is a time consuming task. They demand proper grooming every 8 to 10 weeks, and a high amount of brushing through their coat once every day. They can be suited to apartment life, but prefer a large yard to run around in.

Pet door is found to be convenient by many owners of companion animals, especially dogs and cats; it lets the pets come and go as they please, reducing the need for pet-owners to let or take the pet outside manually, and restraining unwanted behavior such as loud vocalization or noise to be let outside and scratching on doors or walls. They also help ensure that a pet left outdoors can safely get back in the house anytime they want.

I have listed here some of the benefits of having dog doors or pet doors:

1. Health Benefit - Dogs love to explore and discover things on their own. Freedom can improve pet confidence and attitude - Dog Doors provide your pet with emotional encouragement which helps keep your pet alert.
