We rescued an Anatolian Shepherd. He is about 4 or 5 years old. Had an abusive relationship with his previous 2 owners. His last owner used him to watch his few goats/sheep. He was free to roam as they lived in the country on farmland. He was a barn dog, never in the house. The previous owner brought him to us. We gave him a bath, fed him (he acted like he never ate) We keep him in the house with many walks outside. We have always trained our dogs to stay in the yard. We do live in a residential area but have a mountain behind our house. Between the yard and the mountain it kept our dogs satisfied. We never tie them up. We want to train Duke to stay in our yard, too. We try walking him around the perimeter of our house and tell him no when he tries to go off our property. He cries awful when we put the leash on him. I know he wants to run but until we can train him, we can't let him run. Any suggestions? Is it to late to train him not to go out of our yard? We all love him and he loves us. He trained real fast when it came to peeing in the house. 6 firm No's and he didn't lift his leg anymore. We don't want to give him up but we will do what's best for his happiness. Thanks for any help.
