Free to a good home! in Tucson, Arizona For Sale

I've never put a dog up for adoption so I'm not sure how this should work. I have a German Shepherd/Heeler mix named Luke(or Luke Skywalker) and I rather not give him up but I am in the military and I'm getting sent to Japan and will be living in the base dorms where I can't have pets. He is almost 2 years old and about 50 lbs and has light brown fur. He's great with people and other dogs and seems to be most comfortable around other dogs. I think it would be in your best interest to have a fenced in backyard to simplify transition potty training. If you are interested contact me on here.
