I like German Shepherds. They're a fun medium to large-sized working dog and I hope I can get one some day
They are great dogs.  Very intelligent and friendly
Yes, and I'm surprised they are a relatively new breed of dog. they have only been around since 1899
Yes, you would think they would have been around longer.  They are great for working dogs.  They are used as companion dogs and search and rescue, among others
They are great for search and rescue, due to their strength, intelligence, trainability, and obedience
