What type of famous international event is "Crufts" that's held in the United Kingdom every year?

Crufts is an umbrella term for an international canine event held annually in the United Kingdom. Crufts is centred on a championship conformation show for dogs but also includes a large trade show of mainly dog-related goods and services and competitions in dog agility, obedience, flyball and heelwork to music.

The event is organised and hosted by the Kennel Club. It is held over four days (Thursday to Sunday) in early March at the National Exhibition Centre (NEC) in Birmingham, England. The highest profile dog show in British culture, it is the largest show of its kind in the world, as declared by Guinness World Records.

Crufts consists of several competitions occurring at the same time. The main competition is for the Best in Show award, which is hotly contested by dogs and their owners throughout the world.

Crufts was named after its founder, Charles Cruft, who worked as general manager for a dog biscuit manufacturer, travelling to dog shows both in the United Kingdom and internationally, which allowed him to establish contacts and understand the need for higher standards for dog shows. In 1886, Cruft's first dog show, billed as the "First Great Terrier Show", had 57 classes and 600 entries. Today, it is estimated that an average 28,000 dogs take part in Crufts each year, with an estimated 160,000 human visitors attending the show.
