Ever thought about what makes a good walk for a dog? What ingredients are necessary for a satisfied mutt?...

Mud... mud... mud.. water.. brambles... sticks... smells.. space to run... did I mention mud?...

But how do dogs communicate that they're enjoying a walk, how to they interact with the space and how on earth would you create a dog's map of The Park?

Perhaps a 'wagometer', measuring both horizontal and vertical movement of the dog's tail. Frequency and direction of tail wag would be impoartant variables.
