>I accept that sooner or later many of our dogs get out somehow and take themselves off for a merry romp on their own.<
My dogs have never got out.I would utterly freak if they dissapeared,and most surprised as the front door and back gate could stay open all day and they wouldnt venture out,if i'm not out the front then they have no interest in it.But my dogs have no road sense so if for some reason they did take themselves for a romp i doubt very much they would make it back alive :(
As for dogs acting different when not around their owners,i do agree with this.I've found this mostly goes for aggressive or anxious dogs,who's owners are equally anxious transfering their angst on to their dogs.I sometimes walk a dog, who is a nightmare when out with her owner,but is fine with me.
>How would you react if told your dog had an alter ego when not in your presence?<
I think they probably do believe you,wouldnt the grandkids tell her?She may be to embarrased to acknowledge it when you tell her??
I would want to be told straight out,but not in a lecture kind of way,not in a softly around about way either as this can often come over as condescending.
