12 Weeks old Male German Shepherd

I need to get my puppy back home. His name is Benji, 12 weeks old. We've got him with plans to move into a house we could keep him in, but our situation has changed and keeping him in an apartment isn't fair. He's a wonderful, intelligent puppy. He's trained in crate and potty, and he's very calm. He's going to be a very large good dog. With other dogs he's nice and likes to walk and play with his toys. He had his first round of shots and was twice dewormed. I'm asking for a $350 rehoming fee that's $150 less than I paid at the age of 9 weeks. He's going to come with leash, collar, crate and toys. I just want to make sure he's going to a nice family that's going to take care of him.
