Another sleepless night

its getting old. there are two of them now. they show up and sleep on the porch all curled up. and Ole barks all night long to let us know they are still there and dont belong here and he doesnt approve!! which means NO SLEEP for us. why cant these people keep their dogs home? why have they chosen our porch to sleep on more often than not? and there is NOTHING we can do. although I suppose if we charged them with the damage to the windows from their dog they MIGHT get the message but I doubt it. I seriously doubt it. 50 bucks and a trip to the shelter didnt bother them any, the dog was back the next day. GRRRR. Short of moving we can do nothing.
