Some of the best trained pooches in the United States have battled it out at the national finals of the Incredible Dog Challenge in Missouri.
More than 50 of the most athletic dogs from across America took part in the compeition which tests a pooch's skills, including speed and agility.
The dogs jumped, chased and dived their way into the record books in what was the 15th annual challenge.
Organisers told Sportreview.com they hoped the event would give the pets and their owners a new 'leash on life' and that they would be able to 'collar' some more spectators for next year's competition.
