So you are a big dog? I am a big cat!
This is a smartphone snapshot, my apologies for poor composition. It felt like this was The Decisive Moment as Henri Cartier-Bresson defined it :-P and the moment was not going to last long enough for me to find my camera and properly position myself and the actors in this scene.
They were separated by the glass door, if you wonder, so the dog was not in any danger!
This is my photo for animal photography contest. Thank you
