I couldn't easily sum up the spirit of the dog, and it'd be hard to capture it in one photo. So much goes into that spirit - devotion, tenacity, joy, dopiness, strength and more. But here's an attempt in 24 photos to record a bit of the spirit of the domestic dog.
Does it come close? Let me know. And if you leave a comment, you'll be in the draw to win a copy of The Spirit of the Dog, a stunning new book exploring the history of the dog and its special place in human hearts (thanks to New Holland).
Playfulness: a ball, a yard, and a sunny day are Brodie's reasons to be happy.
Eagerness: Neo is ready to play whatever you want to play.
Dignity: Ludo, in his wedding outfit, gives a confident stare. Perhaps he does not quite realise the extent of our view.
Spring: Digby levitates.
Alertness: Mila guards her master's front door and gumboots.
Stoic spirit: Mr Poppy dresses up for the cold.
Pride: Archie makes sure he looks perfect for the camera.
Sleep of the innocent: tiny Kelpie pup Scout runs out of puff.
Sleep of the tuckered out: Betty Boo gives it 100 per cent.
Duty: Miss Piggy feeds her new family.
Quiet: Chloe checks out, just for a while.
Sweet-naturedness: Molly and Kita are adorable, and both seem to be thinking about food.
Insight: the penetrating Dachshund gaze of Mithu. He sees right into you...
Patience: not, perhaps, a true canine virtue, but Marlee seems to be showing it.
Determination: Ridgeback pup Tui makes her entrance. But it's not such a good fit these days.
Readiness to please: Arlo is a dream to train, I'm told - he's learning how to shut the door, which is a holy grail for any dog owner.
Loyalty: Odin sticks with his favourite toy.
Modesty: Eddie is master of the table.
Chase: Clio goes for the ball.
Catch: Teef claims the frisbee.
Return: Ollie brings it back.
Magnificence: Teddy, Tui and Scally Wag wonder who invited you.
Joy: The beauty of a dog's spirit shows on the face - Amber, Lexi and Shadow.
