I have a GSD!! Lady always has a puppy smile on her face. We have a huge yard she loves to play in(and bark to her friends) and she as a nice room to play in with dozens of toys!! Lady is not a housepet, she is a part of the family. She loves being part of the family and is treated like one. Lady is 75 pounds and very energetic! I play with her almost everyday, just like I play with Sally and Floppsy.
