Shadow was the only dog I had as a small pup 15 years ago. I slept on a camp bed in the loungeroom with him on a bed on the floor next to me for a few days. When he whinged I hung my arm over the side or comforted him. I still have claw scars on my arm, lol. After a few days he moved back to our bedroom with me.
I would take him outside after eating and at other times.
With Pretty girl, she was older when my father in law got her, about 8 months. Here she is a house dog, over there an outside one. With her I, ummmm, took her out with the command widdle widdle (same one Shads had) and I peed on the lawn too so she would get the connection, lol. I am on a farm though with no neighbours. She has never had an accident in the house and goes to the door when she needs or wants to go out.
I lied, Blacky (found as a quivering abused wreck was about 3 months old I think) I did the same as I did for Shads. About 6 years of age he decided he preferred to be permanently outside till he passed at about 16yrs of age.
