This dog show has been running since Victorian times, and was initially set up by a fella called Charles Cruft, after he landed a job with James Spratt, the inventor of dog biscuits. There's a good pub quiz question, if you ever need one. These days the show is one of the largest dog events in the world, and celebrates every role that dogs play in our lives.

Live from the NEC in Birmingham, Clare Balding hosts the Channel 4 event, where a packed programme includes judging of the Terrier and Hound groups and highlights of the Agility and Flyball. Clare also meets last year's Crufts winner Devon, who is competing in the Eukanuba World Challenge - a league of nations-style competition for top winners from different countries. Kate Beavan and Nim Patel team up to talk about dog health and welfare, Iwan Thomas reports on dog socialisation, and there's an appearance from cat-detection dog Molly.
