Well when I was at the shelter today a family brought in their shepherd. They said he was purebred and had been kept outside his whole life because they couldnt house break him when he was a puppy. He is a very sweet dog and a very nice looking shepherd. He does have a bit of cage aggression, he doesnt act like he wants to eat you but he barks a lot at you, not sure if it is the stress of being in a keenl for the first time or what. He knows how to sit. well here he is... if interested please email me at pitbulls4me@comcast.net!!
