Squirrel Photo with a difference

Yes, it's another squirrel photo from me, but I've only had about 3 or 4 over the past year and a half.
This one is different though. It''s through the front window from the sitting room and there's a dog in the picture as well!
It was Jonty barking that made us go into the room, thinking there was a cat out the front, but when I saw the squirrel I went back to grab the camera.
By then it was hotfooting it across the lawn and I just managed to catch it.
It wasn't until I downloaded it to the PC that I noticed Jonty's reflection in the window.
