If cats are works of art, arranging their sculpted selves all around your home, then what are dogs? I think they must be like those optical puzzles - the ones that look like either a young or an old woman depending on how you squint. Because with a dog, one moment it's a stirring portrait of power and dignity, and then (squint a bit) it's a clown falling on its bum.

Then a bit of dignity shines through; then it's a cartoon character again, snapping at a moth or fleeing its own fart.

So here are some moments of dignity and some moments where the dignity is let down a bit. And some moments with a little of both.

Cover-dog is Expo, a former agility dog whose interests include swimming, tennis balls and road trips.

Bandit's a purebred English Staffordshire Bull Terrier who's turning 5 this year.

Stately poses that went slightly awry... Pebbles (left) and Clay the curious Kelpie.

The sculptural lines of Sam the Greyhound (adopted through Greyhounds as Pets). Thanks for the photo, Falyn.

Sunlit and jewelled with seawater, Bella is like some glamorous Bond girl - though Halle Berry never licked her nostrils that way.

Chloe was bought unwittingly from a puppy mill, but has turned out to be a great house dog (if a bit of a rascal), according to owner Alex.

Thirteen-year-old Tom still loves to be among his toys.

Being a Rottie pup is a serious business for Lucifer, who's no longer a "little" Lucifer.

The majestic Bullmastiff pose is only slightly undercut by the balletic bollard-balancing. Meanwhile, Morgan is itching to give you a muddy handshake.

When Buddy the German Shepherd pup is alert to something, his ears actually applaud. The sprinkler-hugging terrier is named Elsa.

The calm poise of Jess.

The beautiful face of Moss, a much-loved family pet till her death last year. RIP Moss.

Fixing the camera with a mysterious gaze are Miley Bear (left) and Buddie.

Arlo would likie to be a few feet taller.

Barney's a nearly-year-old retradoodle, and with all that hair it's no wonder he likes to chill outside or in the water.

Harden your heart to that gaze if you can - Clover is an English Cocker Spaniel and I'm told her nature is as lovely as her looks.

Here's our beefcake centrefold for the day - Rosco.

Finally, meet Samson the British Bulldog pup, as solid as the tree stump he's sunning himself on. Thanks for the photo, Michelle.
