Every man and his dog will be at Hunterville's annual Eukanuba Shepherds' Shemozzle on the 29th October.
The event, held in the Rangitiki District, is part of an effort to celebrate New Zealand's very own dog breed, the huntaway.
Around 5000 spectators will turn out to watch the dogs and their shepards race over 3kms of hills, mud slides, swamps and other obstacles.
Last year 380 contestants carried bull's testicles in their mouths as they scrambled through mud and pushed their huntaways in wheelbarrows.
This year promises to be just as tough with a top prize of $1000 cash, with a further $4000 prize pool.
