Visitors at the grooming competition in the small Kent village of Higham quickly turned violent when 2,000 people attended and traffic began to pile up.
One 18-year-old volunteer was punched by two separate men as he tried to manage the car park and angry dog-owners turned on the organisers when their pets lost, demanding compensation for a ruined bank holiday.
Rachel Hodges, who started the family competition five years ago, accepted 700 entrants and expected a maximum of 1,000 visitors at the village’s Memorial Hall playing fields.
But the former Crufts-winning owner, 49, was so shocked by the scenes which developed she has decided to cancel all future events.
“I had rubbish thrown at me and I had abuse thrown at me. Girls in the tent who were taking donations were reduced to tears,” she said.
