Neighbourhood watch

My two love to watch what's going on outside the front but if anyone or dare I say it, a cat walks by then mayhem ensues! 
I found a Doris' look a like! From the back anyway, a fellow blipper put up a photo and I thought it was Doris when I saw it. She is a rescue from Cyprus, same people as Percy, so was very surprised to see a very similar dog in this country.
