One dog owner was left holding her head in her hands at Crufts this weekend, after her cross-breed Libby squatted for an impromptu bathroom break during the dog agility course.
The embarrassing incident, named 'Hilarious! Dog Agility Course Fail' on YouTube, has had over 30,000 views.
The sleek black dog had leapt over obstacles and navigated its way around posts with elegance, until nature eventually called.
Unabashed, Libby took her time to finish her business, despite the 6,000 onlookers. A plastic bag was handed to her red-faced owner, left to scoop up the doggy mess, while Libby wandered off, wagging her tail.
The duo were immediately disqualified, though the commentators could not resist punning: "A dog's got to do what a dog's got to do. What a shame. Disqualified - and it was a good run too."
Meanwhile there were joyful tears from Crufts winner Margaret Anderson, the breeder of the Best in Show.
The breeder of the Lhasa Apso, called Elizabeth, said she found it so hard to believe she was not sure she was actually awake.
The pair beat off opposition from more than 21,000 dogs, including six others which reached the final at Birmingham's NEC yesterday.
Best In Show
Seven-year-old Elizabeth won the Best Utility category then went on to be pronounced Best in Show after four days of competition.
"I can't believe it," Ms Anderson said.
"I'm, sure somebody's going to pinch me in a minute and I'll wake up and it'll all be a dream.
"It hasn't sunk at all. I'll go home and probably burst out crying."
Elizabeth's win may be just as much her doing as her owner's, because of her love of the limelight.
"She's a very easy going dog, she's very laid back," Ms Anderson, from Coventry in Warwickshire, said.
"She loves showing, she's always loved her show career, the bigger the applause the more she loves it.
"So she's been a very easy dog to show - she just adores it."
Elizabeth may well go out on a high with her Crufts win and retire from the spotlight, Ms Anderson said.
"To take her out again to be beaten seems silly somehow.
"Although she's still a young baby, she's seven and in Lhasa Apso that's still quite young."
Reserve Best in Show went to Brutus, a three-year-old Newfoundland, winner of the Working category.
Also in the final were: Dreamer, a Pomeranian, who won the toy group; Irish Water Spaniel Merlin, who won the Gundog Group;
Jimmy, an Old English Sheepdog who won the Pastoral category; Paris, a Norwich Terrier who took first place in the Terrier group; and Luke, a Borzoi who took the best Hound title.
