I just bought a german shepard but don't know what to expect. I'm used to small dogs.
You're going to love your new German Shepherd! They are such smart dogs! They are not only strong and intelligent, but very easy to train and are very obedient! 
I am looking forward to this new adventure with him for sure!
They were originally bred for herding sheep! They have shown their value in many other areas since then!
They seem very loyal
They are extremely loyal! That makes them a great breed for folks who need disability assistance. 
Maybe I will consider to adopt one someday
You definitely should! I love their distinctive look. You can tell it's a German Shepherd by their long square-cut muzzle, domed forehead and black nose. Such beautiful animals!
They really are gorgeous dogs. 
They're hugely popular too! The American Kennel Club states that the German Shepherd is the second most registered breed in the US!
