Lovely shot, he/she looks devoted to you, but we all know it was really about the double self portrait, but red shorts with a black top! ;D
Just to be clear, what I'm really saying is wow fantastic detail.
That is one expressive look, we had a border collie years ago, first time I realised there was a problem was when I heard her yelp when we were running along the beach (that just made me feel old, I don't run now!) she had run slap bang in to a wooden post left over from a groin. The vet said she probably only had 10% to 20% vision, no more running along the beach at dusk for her.
I think Dave is going blind!
I was stood in the open about 30 yards away, and he still didn't spot me, and got very worried (see the expression) about where I had gone! :-\
