follow your nose

I was invited by Dr. Geoffrey Farrer- Brown to contribute to an exhibition by selected artists exploring the power of a dog's nose, and its use in medical detection. Above is the first of 3 wax maquettes looking at how a dog's movement and pose support this action of following a scent.

The Medical Detection Dogs charity, which this touring exhibition project will support, used a similar image as its logo.

A third maquette - I like the curve of his back and tail, and the very active turn up of head and paw.
One of these 3 will be developed further into a life size bronze sculpture, to greet people when they enter the exhibition. Which one will it be?
