Sara,
That had me in fits of laughter too ........
My Mum went away for a few days without her dog (very rare), and my Grandparents stayed at the house.
Well, Pugsley went out to do his business in the afternoon, and no matter what they did, he would NOT come in. He was waiting for my Mum.

Eventually, at 8pm at night, with my Gran lying on her stomach on the floor near the backdoor, and Pugsley sitting outside the back door staring in, she managed to coax him in .......... took about an hour

He did that every night .......
