On Friday evening, as we were sitting quietly at dinner, Penny leapt to her feet and shot out the back through the doggy door. Magnificently loud and ferocious barking echoed back into the house and I raced out to see what was going on.
What I think was happening was that a guy from next door had come over our side fence (or maybe he was up on the fence), looking for a kitten (or maybe a black cat) - are you getting the idea that it was all uproar and confusion in the dark? - and Penny was defending the property (or maybe trying to kill/ play with the cat/kitten or whatever).
Eventually the guy announced, 'We're sorted, sorry...sorry,' and disappeared with the cat/kitten or whatever.
In case I sound extremely naive about all this, I do think it was actually a neighbour looking for a kitten, because I think I heard 'puss, puss, puss' before all the uproar started.
Penny was a magnificent guard dog!
