Up to 22,000 dogs are competing for the prestigious title of Best in Show at the NEC in Birmingham. But first they must attract the attention of the judges during the four-day contest which has already seen gundogs like this Afghan and American cocker spaniel put through their paces. The dogwalk parade began in earnest at 5am with competitors and their owners trotting into the arena sporting a variety of eye-catching onesies, fleeces and even colourful snoods to keep their ears extra warm - and their pristine coats in tip-top condition.
Founded by Charles Cruft in the late 19th century, each day is dedicated to a different breed - gundog, working and pastoral, terrier and hound and toy and utility categories.
There are six show rings, including the main arena and this year five pets who have gone above and beyond the call of duty are in the running for Crufts' dog hero competition.
The event has courted controversy in recent years with protesters branding the competition "cruel".

The overall winner in 1918 was Tease, a whippet from Scotland, but Betway is backing a gundog to walk away with the top prize this year.
Odds are currently at 11/8 with terriers nipping at their heels at 7/4.
