Audiences have the chance to watch agility contests, freestyle heelwork to music and flyball – head-to-head relay races between dog teams – and a display by the West Midlands Police Dog team, organisers have said.
Last year for the first time, a dog from Italy won best in show.
Miuccia, a four-year-old whippet from Venice, came out top among more than 18,000 dogs from around the world to take the top award.
For this year’s show, doors open each day from 08:15 GMT and close at 18:30 until Saturday, before an 18:00 finish, on Sunday.
Events last until 20:05 each day, except on Sunday when the best in show winner will be announced from 20:30.
