The photo I took of these three was a lucky break,  that they were all sitting so quietly together on the sofa  (and such a nice Chesterfield too).  Haggis and Pedro at the front are both Whippets, while behind them is Chester who is an Italian Greyhound.   Although whippets are not large dogs,  Italian Greyhounds are tiny,  like Chihuahuas on stilts,  so it is not an optical illusion, the dog behind is small compared to the others.   Too bad there was not a Greyhound there too.
