Diva dogs will be howling, dancing and performing party pieces in a battle to be named Pup Idol at a canine show.
Thousands of dogs and their owners are heading to the show
The Pup Idol talent contest is part of the Wag and Bone Show at Windsor Great Park in Berkshire on Saturday.
Organisers also hope to get 1,000 dogs to do a two-minute sit stay at the same time, for a new Guinness World Record.
Some 3,000 dogs and their owners are expected at the show, being organised by seven animal charities including Battersea Dogs Home and the Blue Cross.
Would-be owners will also be able to view photos of rescued dogs available for adoption.
Beverley Cuddy, editor of Dogs Today, told BBC News: "Dogs will be doing two-minute auditions in front of the Pup Idol panel and anything goes.
"We've previously seen tap dancing dogs and a dog that can sing and strip to the Full Monty. It's a real eye-opener."
Last year's Pup Idol was won jointly by Jake, a cairn terrier cross from Cornwall who had taught himself to do football tricks, and Daz, a Staffordshire terrier who performed a dance routine to music despite being deaf.
