"If I didn't already own 18 dogs, I'd adopt them all myself," said Janinie Hinton from the Saving Hope Foundation.
"Dogs bring so much joy to the world, and it breaks my heart that so many of them are going without the love they deserve. Please, if you have room in your heart, and your home, adopt one today."
The initiative was the brainchild of the ad agency Colenso BBDO, which works with pet supplies company Pedigree.
Pedigree often lends support to a number of charitable causes around the country, particularly those involved in finding homes for animals.
Colenso BBDO's Nico Ainsworth said this campaign was largely designed to help out the Saving Hope Foundation.
"We are so lucky to be able to lend a little creativity to shine a spotlight on the incredible work they do, and help find loving homes for their awesome pups."
