I have read all the posts. I can't respond to all of you, but thanks for posting. It will be awhile before we get a dog. I am not going to just rush out and get one. For one thing, we have to make sure the fence is secure, get a doghouse, and so on.
I do have one question for the person (or persons) who keep saying an outside dog will be crazy. When I was growing up our dogs were always outside (our trailer was way too small for pets and people, too). None of the dogs we had were crazy or attention starved. Maybe this is because we always had more than one dog? 
My favorite dog of all time was a German Shepherd, Border Collie mix. My grandpa's Border Collie had a litter of pups one Summer. She was a biter, so no one played much with the pups and they were kind of wild. One day while we were visiting my Grandpa I was sitting in the yard, looking at the puppies from a safe distance. One of the male puppies saw me and ambled over and crawled up in my lap. I begged Grandpa to let me have him. Mom said that since the pup had picked me, he should be mine. I was about 8 then and that dog was my constant companion until I went to college. We named him Poe. Every school day about 3:00, Poe would sit up, prick his ears,  and start looking down the road, anticipating my arrival from school. One morning he followed me to the bus stop, which was about a mile from our house. It was a warm morning, so I hung my jacket in the woods instead of taking it to school. When the bus dropped me off that afternoon, Poe was still there, guarding my jacket. He knew how to get home and could have gone at any time. I guess it was my scent that kept him there.  He used to lay his head on my leg and grin when he wanted affection. He is a fixture in almost all my memories of growing up out there in the boondocks.  That's the kind of dog experience I wish my boy could have.
