When Kratu the Romanian rescue dog went rogue during an agility trial at Crufts in 2018 he ended up the star of the show, delighting everyone who watched with his hilarious performance.
Chased by owner Tess Swan, Kratu bounded gleefully around the course, missing jumps, ignoring obstacles and even running over to say hello to a group of volunteers mid-way through.
Then he ran into a plastic tunnel and failed to come out the other side, finally emerging from the end he had gone in.
