Elizabeth the Lhasa Apso wasn't the only winner at Crufts 2012. Meet Libby -- the pup who decided to take a dump during her turn at the agility competition.

A video of the incident, simply named, HILARIOUS -- Dog takes a dump on TV, has now gone viral, with more than 220,000 views on Crufts' YouTube page.

Libby, a five-and-a-half year old cross-breed, appeared to be making good progress on the course when, 30 seconds into her run, she stopped to take a bathroom break.

The crowd at Birmingham's National Exhibition Centre sighed, almost in unison, along with the television commentators.

Oh no. It was a good run too . . . a dog's gotta do, what a dog's gotta do. What a shame. Oh dear. Disqualified, says one commentator.

The trainer, who buried her head in her hands at the sight of Libby's bathroom break, patiently waited for the pup to finish before picking up the poop.

The hilarious video, which picked up steam in viewership over the weekend, also includes a replay of the doggy dump, complete with a big red X over the dog's behind.

Crufts, an annual four-day competition, hosted more than 21,000 canines in Birmingham last week. Other big winners included Dreamer the Pomeranian and Buster the Spaniel, who won Best of Breed in their individual categories. Buster also took home the prizes for Man's Best Friend and Friends for Life, in recognition of his tours in Afghanistan, Iraq and Bosnia.

Crufts, the largest dog show in the world, held its first competition in 1891. In comparison, the annual Westminster Kennel Club Dog Show in New York City hosts 2,500 dogs over a two-day period every February.
