The Dogs That Built New Zealand

Before first light, on farms across the South Island high country, the dogs are already restless in their kennels. They know the sound of gumboots on gravel. They know what that sound means. In an hour, they will be on the back of a quad bike, then off it, working the tussock faces that a person could not cover on foot in a day. The farmer knows each dog's name, each dog's working style, each dog's weaknesses on a cold morning. This is a partnership. But it is not the word farmers typically use.

The word is 'partner,' though most farmers would not use it without some discomfort. Working dogs in New Zealand occupy a category that sits awkwardly between the two poles of the modern pet debate — neither purely functional asset nor companion animal, but something for which the English language has not developed adequate vocabulary. They are indispensable. They are worked hard. And, as science has recently established for the first time, they have been carrying an invisible burden of untreated health conditions for their entire history.

A 150-year tradition

The first formal sheepdog trial in New Zealand was held at Hakataramea, in South Canterbury, in 1889 — thirteen years after the world's first trial, at Bala in north Wales. The New Zealand Sheep Dog Trial Association was founded in 1957 and today coordinates 157 affiliated clubs across the country. Canterbury is the largest regional centre. In 1994, the Wayleggo Cup — a trans-Tasman competition between New Zealand and Australia — formalised a rivalry that had been building for a century. The NZSDTA is not merely a sporting body; it functions as the Huntaway's de facto breed registry. Only dogs that win at NZSDTA trials may enter the studbook.

The Huntaway: a breed that NZ made

New Zealand's working dog population divides broadly into two functional types. The heading dog — typically a Border Collie or Huntaway-Border cross — works by eye and crouching pressure, gathering sheep and bringing them toward the shepherd at close to medium range. The Huntaway works by voice, driving sheep away from the shepherd at long range, its deep bark carrying across terrain that would swallow a silent dog entirely. The Huntaway is the only dog breed indigenous to New Zealand. Formally recognised by the New Zealand Kennel Club in August 2013, it accounts for approximately 70 percent of the working dog population.

The study that finally looked

For most of the history of the working farm dog in New Zealand, their health was a matter of empirical management by farmers, not systematic veterinary surveillance. That changed between 2014 and 2018, when the TeamMate project — a collaboration between Massey University's School of Veterinary Science and the working-dog farming community — conducted the first study of its kind at scale. Led by researcher Katja Isaksen and colleagues, the study examined 641 dogs on 116 farms across Otago and Canterbury, giving every dog a structured clinical examination. The findings were published in BMC Veterinary Research in 2020.

The researchers were careful to note that the findings did not indicate deliberate neglect. Farmers who participated in the study cared about their dogs. But caring, without systematic veterinary data, produces suboptimal outcomes — because you cannot improve what you cannot measure. The TeamMate study gave the working-dog farming community, for the first time, a systematic picture of what their dogs were carrying.

Reading the genome of a working dog

A parallel research programme at Massey University, led by Professor Matt Littlejohn, sequenced the DNA of 249 working dogs and analysed 19 million genetic variants. The Right Dog for the Job study identified five genetic markers with direct health implications: a CUBN variant associated with vitamin B12 malabsorption; a CLN8 variant linked to neurodegeneration; a SGSH variant associated with mucopolysaccharidosis; a SOD1 variant linked to degenerative myelopathy; and a VWF variant associated with von Willebrand disease. The research enables genetic screening of working dogs for the first time — allowing farmers to make breeding decisions on the basis of health data, not guesswork.

The retirement problem

A working farm dog's career typically ends between six and ten years of age — when the body begins to be unable to sustain the physical demands of a full working day on steep country. What happens next has historically been a matter of individual farmer decision-making, with outcomes ranging from a comfortable retirement on the farm to euthanasia. The Retired Working Dogs charity has changed that picture. The organisation has rehomed more than 1,800 Huntaways and other working farm dogs over the past decade, building a nationwide foster and adoption network that manages the transition from farm to home. Retired Huntaways are typically well-socialised to humans and adapt to companion-dog life with patient owners and adequate space.

The data era begins

Two hundred thousand dogs are on those hills right now, in the pre-dawn dark, waiting for the sound of gumboots on gravel. They have been there, in various forms, for a hundred and fifty years — building a pastoral economy, shaping a national identity, carrying an invisible burden of untreated health conditions that nobody had thought to measure until 2014. The data era has arrived. It is late. But it is here.
