When I ask my dog who's that?Because I know somebody is at the front door he runs to the front door and starts barking. Sometimes I am in the backyard and they ring me.He can't hear them knocking. He is a rescue dog and once a week I take him back where I got him from, she loves him. The woman's name is Leanne and I tell him he is going for his visit today. His eyes light up and when we go out the front for his walk he wants to go straight over the road because she has a business down the road on the that side of the road. When we walk up the road which is at least a Kilometre long and I tell him he is going to see Leanne he wants to cross the road all the way. Because he knows that is where her business is. Mad but true.
