Mark Roberts, from Liverpool, interrupted proceedings of the pure breed dog show at Birmingham’s NEC, running onto the floor during the Gundog competition.
He was wearing nothing but shoes, socks and a cat-shaped mask covering his modesty with the words “I streak.com” written on his chest.
He was quickly escorted from the area, allowing judging to continue.
‘Professional streaker’ Mr Roberts has become well known for his naked exploits after bearing all at more than 380 public and sporting events.
He caused chaos at last year’s Scouseology awards for underprivileged children when he invaded the stage naked, and claimed he broke his toe when he was wrestled to the ground. He is also remembered for clambering on Fred Talbot’s weather map in the altogether during This Morning’s Albert Dock heydey.
Later, a Hungarian Vizsla took the title of Best in Show.
The six-year-old, whose pet name is Yogi, beat off competition from six other prize pooches in the culmination of the four-day show.
Taking second place was a Scottish Terrier from Russia, whose pet name is Rico.
Organisers the Kennel Club said almost 22,000 dogs across 187 breeds were entered into this year's Best in Show competition.
