Luke - just cruising

You have seen Luke before but he is such a cool dude I thought I would take him again. He has got his yellow duck with him and although he loves to play with it, he never distroys it.
His health is good but he still gets very tired after his back surgery, last year, for a slipped disc. He had to be confined, in a pen for 3 months and was very good about it.
He can run round the house now but one back leg does not quite work as it use to.
Never mind, he is happy and we love him.
