SINGAPORE — A Singaporean environmentalist and freelance photojournalist has received a US$10,000 (S$13,269) National Geographic Explorer grant, which will allow her to research on a deadly and highly contagious disease affecting dogs in the Himalayas.

Ms Debby Ng, 35, will be heading to Nepal from May to June to study whether domestic dogs in Nepal Himalaya, a large number of which are free-roaming, have been exposed to the Canine Distemper Virus (CDV).

The CDV is a viral disease that affects a wide variety of animal families, including domesticated and wild animals.

Ms Ng was given the grant in late-September last year but she only shared the news on her Facebook page on Monday (Jan 1). “I wanted to make sure it was all real,” she wrote in the Facebook post. Over the past months, she has been busy preparing and assembling a team for her study.

While she will only have two months in spring to complete her research, she said: “Field work is all about working with the time Nature gives you!”

Speaking to TODAY, Ms Ng said a veterinarian will be accompanying her, alongside two or three research assistants to help with interviewing locals and collecting blood samples from dogs.

A recent graduate from the University of Tasmania with a Bachelor of Science (Zoology and Geography), Ms Ng will be using the findings from her study to pursue her Honours.

Ms Ng is no stranger to the mountainous region or the dogs that inhabit the area either. She is also the co-founder of the Himalayan Mutt Project, a non-profit organisation that helps vaccinate and neuter domestic dogs in impoverished villages in Nepal.

Explaining the significance of the study, Ms Ng said that such free-roaming dogs have been recognised by wildlife researchers as a “source of infection for several disease outbreaks affecting wild carnivores, in all continents except Antarctica” since they have a higher tendency to interact with wildlife and pass diseases on.

In 1994, dogs infected with CDV were responsible for wiping out close to 30 per cent of the lion population in the Serengeti National Park in northern Tanzania.

Humans are not spared from the impact of the virus. It can be passed to livestock, which would in turn affect communities dependent on them through loss of income when their livestock die from the virus.

Ms Ng said the grant would cover all the field and laboratory costs for the intended duration of the study. “Utilised wisely and efficiently, it can profoundly improve our understanding of how diseases are transmitted across a landscape,” she said.

When asked why she chose to focus her work in Nepal, she said: “I have a passion for working with communities who want to protect their environment. The communities I work with...are very eager to resolve the problem with dogs.”

She added: “(Nepal) is a global tourist destination, and brings joy and even meaning to life for many people...This is a precious landscape to us all, but most importantly to the people of Nepal.”

Turning her attention to Singapore, she said she welcomed the recent announcement by the Agri-Food and Veterinary Authority of Singapore on a nationwide sterilisation effort. “There was a soft sigh (of relief) in my heart. It is a wonderful breakthrough,” she said.

Having carried out sterilisation of dogs in Nepal for more than three years, she noted that over there, “healthy but unwanted dogs are hung, drowned, shot, and poisoned”.

Even if culled humanely with drugs, routine mass euthanasia is a heavy economic burden on society. “The cost of one euthanasia dose can neuter two dogs,” she said. “The alternative to not killing them is turning them to a life on the streets or wilderness areas where they get into fights with other dogs.”
