Big brands are known to be dogged in their pursuit of publicity.
The Women's Institute stripped off to sell calendars. Red Bull even dropped daredevil Felix Baumgartner from space.
Now, though, some companies are quite literally giving consumers paws for thought - by employing dogs and cats to promote their brands, reports the Daily Mail.
Pooches across the UK are being paid up to £100 an hour to star in ad campaigns, feature in pop videos and model in photoshoots for everything from Vogue to High Street fashion chains.
The big draw for advertisers is that the chosen animals already have thousands of followers, with high-profile social media pages set up by their canny owners.
As bizarre as it might seem, some are already considered extremely influential.
It means, of course, that many must follow strict organic meat diets with strenuous daily walks to maintain fitness and looks.
But while it might sound barking, it is in fact a highly lucrative business, with animals earning thousands a year for their owners.
Social media has transformed advertising.
While celebrities can still earn millions to front campaigns, more subtle forms of promotion are now widespread throughout the internet.
Young 'vloggers' such as Zoella act as ambassadors for brands and mention them in posts, while Instagram and Twitter give advertisers access to 'influencers' who can promote products instantly to followers.
The trend has led to the emergence of casting agencies for the most ambitious pets and owners.
Melody Lewis, who set up PetLondon Models, said: "It's amazing how quickly these animals take off."
The key, says Layla Flaherty, who runs pet casting agency Urban Paws, is that animals are generally more popular than human celebrities.
"You'd be hard pushed to find an advert with a cute chihuahua or kitten annoying," she said.

A relative newcomer, pug Barry has already starred in a Virgin Media campaign.
His fame began when owner Nicole Barr, 29, from Coventry, realised pictures of her dog were proving more popular than her own selfies.
"I'd put a photo of me on and no one would bother, but if it was Barry, everyone liked it," she said.
"So I decided to make the page his instead. Then a friend suggested I sign him with a model agency. He is so well behaved and calm."

The most-followed Maltese dog in the world was 'discovered' at a dog show seven years ago - where she was taking part in a fish treat-eating competition.
It was, owner Marianne Di Fiouw explains, her "Kate Moss moment".
Now Lilliput, from London, travels the world and has worked with - appropriately - the Pet Shop Boys, Good Housekeeping, River Island and Metro Bank.
Former finance worker Marianne, 35, said: "She's so self-deprecating and cute and that's part of her charm."
And the hot new CATwalk star: Starina
Proving it's not just about canines, Starina is one of Britain's top cat models.
Her striking eyes - one green and one blue - have attracted Stella McCartney, Thomas Cook Airlines, Hendrick's Gin and Asos.
London owner Sasza Esperanza, 34, said: "She's with me in my handbag everywhere I go... nothing fazes her."
