German Shepherds are intelligent medium-to-large sized working dogs. As well as being one of the most popular dogs in the US, they have found a strong place in the hearts of many professionals. Their ability to learn quickly and respond well to training is coupled with strength and loyalty, making them one of the most loyal dog breeds. But since they love to play and are highly energetic and active, they do need care and attention: these are dogs that really don't like to be left alone.
Once known as Alsatians, the dogs were originally used in Germany to herd and guard sheep. They were also bred for use in the German military, and they served in the trenches during the First World War, where they were able to assist wounded soldiers, carry supplies, and detect enemy movements. Returning soldiers were full of praise for the dog, and they became popular across Europe. Rin Tin Tin was rescued from the battlefield, and became a Hollywood star.
