The cute pooches were photographed by renowned animal snapper Tim Flach to help promote Christmas Jumper Day on December 15.
Save The Children will also be trying to set a world record for the most dogs in Christmas jumpers at an event in Battersea Park, London, on Sunday.
Helena Wiltshire, of Save the Children, said: “For so many families, their furry friends are an integral part of their Christmas celebrations and with the rise of ‘petmas’ presents on the highstreet, we wanted to include man’s best friend as part of our Christmas Jumper Day fun.
“All money raised through Christmas Jumper Day could help us bring essentials like healthcare, education, protection and food to the millions of children around the world who are missing out on the most basic support.”
