Clare Balding presents all the latest action from Crufts, live from the National Exhibition Centre in Birmingham. The first group to be judged is the terriers, with the winner going through to Sunday's Best in Show final. Then it's the Hound Group, with dogs ranging in size from the miniature dachshund to the huge Irish wolfhound. And athleticism and speed are on show in the Flyball heats - with commentary from Jim Rosenthal and Graham Partridge. Ed Jackson and Radzi Chinyanganya present from the heart of the NEC, as the world's greatest dog show gets into full swing. 

Clare Balding presents further live coverage from the National Exhibition Centre in Birmingham, which plays host to thousands of dog lovers this week. Canine athletes of all shapes and sizes bob and weave over, through and around obstacles at top speed on the Agility course in the Main Arena - watched closely by our commentators Jim Rosenthal and Graham Partridge. Vulnerable breeds take centre stage in a very special judging event. Viewers can send in videos of their dogs, and questions for resident vet Dr Paul Manktelow.
