Well people do train their dogs I suppose especially if they are allowed inside the house. Lots of dogs here are not allowed inside the house as they are outside dogs. Our dogs in Marton were all outside dogs and they were taught NOT to go outside the gate onto the road. Sometimes they disobeyed of course !!!!!!!!!!!!! But we were well fenced in. John built a big tall fence along the road side ... took him ages but it is still standing to this day

Plus we had the railway fence along the paddocks side and a stream.
