Thousands of dogs, from all over the world, will be travelling to Birmingham for the 100th Crufts show on Thursday.
Dogs will be put through obedience and agility tests
The four day event at the National Exhibition Centre (NEC) is expected to attract 22,000 dogs and 120,000 visitors.
Dogs will be preened and pampered by their owners before being put through obedience and agility tests.
Crufts chairman Peter Mann said: "The Kennel Club is extremely pleased with the 2003 entry, which reaffirms Crufts to be both the biggest and best dog show in the world."
More than 300 dogs from overseas are also expected to attend the event.
Up until two years ago quarantine laws prevented overseas dog owners from entering the competition, although there have been occasions when dogs have been brought in from the United States, after six months in quarantine, specifically for Crufts.
The first Crufts show to allow dogs from abroad to enter opened in 2001.
Last year, for the first time ever, an overseas-based dog carried off the top prize.
More than 170 different breeds are expected to compete for this year's best-in-show title, which will be awarded on Sunday.
Crufts was founded in 1891 by entrepreneur Charles Cruft, who went into business with James Spratt selling "dog cakes" in London.
The event was initially held at London Olympia before moving to Earl's Court and then Birmingham NEC in 1991.
