A Passion For Making a Difference

in The Lives of Street Dogs and the Communities in Which They Live

The Work

Thrivant Health is blending science, business, and animal welfare know-how to create a new tool for ethically managing street dog populations.

We’re developing a safe, affordable, permanent birth control for male and female dogs. An injectable and humane drug that makes high-volume, high-coverage population control operationally feasible.

  • So animal control agencies can achieve smaller, more stable dog populations without doing harm.
  • So additional human health equity is realized in places of the world that need it most.
  • So public perception and treatment of dogs is improved through reducing conflict between dogs and humans.

The Story

Thrivant Health is a Story Still Being Written
This is the Opening Chapter.

Part One: My Story

I’m Michael Royals.

I run Thrivant Health. Fresh out of veterinary school 20 years ago, I started developing medical devices to help humans. Things such as a better, non-surgical way to treat brain aneurisms, an eye implant to prevent blindness in head injury patients, and even a range of Star Trek-like devices that inject vaccines without needles.

The past decade of vaccine work took me all over the world. And most everywhere were the free-roaming dogs, lining the shady side of buildings, on steps and alleys, and perpetually foraging for food scraps.

Intrigued with these expendable and marginalized street dogs living rough and tumble lives, I began to pay attention. Revealed to me was that the concept of “man’s best friend” doesn’t exist in much of the world. Instead I observed a reluctant, interdependent triangle between the dogs, the human community members, and the government.

Globally, almost half a billion at-large animals are responsible for millions of dog bite cases annually. Victims incur heavy physical and psychological trauma and economic burdens due to loss of income. Governments endure a preventable strain on already stretched public health budgets. Seen as a low-value commodity, dogs become subject to extreme abuse and neglect, a lose-lose situation for all involved.

Trained as a veterinarian with an extensive background in product development and international public health, I decided to do something about it. The result is Thrivant Health, created to catalyze the shift to humane, effective dog population control.

Part Two: The Global Story

Outside of the posh conditions enjoyed by pets in developed nations, 300-500 million dogs are free to roam, reproduce, and cause mayhem. Spread across approximately 164 countries, almost seventy-five percent of the global dog population is on the street, able to form menacing packs and transmit dozens of diseases between each other and to humans. Dog bites account for of 99% of all human rabies cases, resulting in 8.6 billion USD in economic losses annually [1], [2].

Dog population control efforts take many forms. Surgical sterilization is highly effective but resource intensive. In resource-constrained regions, dogs are periodically captured and exterminated by electrocution, drowning, and poisoning. Not only are these methods dangerous and socially unpopular, they actually work against dog ecology. Depopulation inevitably allows an influx of new animals and new disease, continuing the cycle.

Thrivant Health is addressing the root of the problem – how to control breeding – with a contextually-optimized solution that works with dog ecology. Features we are engineering into our product include permanent sterilization in both male and female animals, single-dose efficacy, and to avoid the need for refrigeration, be ambient-temperature stable. Dogs returned to the street can hold their place in the community, preventing an influx of non-sterile dogs, ultimately decreasing overall population size and disease transmission.

We Believe

We believe animal welfare transcends cultures, religions, and socioeconomic status

We pledge to create affordable, accessible population control tools so animal welfare can be maximized. Research in emerging market economies shows that dogs obtained for little or no cost are at the greatest risk of abandonment and abuse, and that community involvement in population control improves attitudes toward animal welfare and builds support for additional veterinary care.

We believe data trumps hype

We are scientists at heart and pledge to use evidence-based impact metrics to demonstrate the effectiveness of our approach to animal population control. Our goal is to inform policy and evolve practices worldwide.

We believe in using business as a force for good

Which is why Thrivant Health was formed as a , a for-profit organization with a legal structure that emphasizes our passion for contributing to the humane economy. Our goals of impacting both public health and animal welfare will play a pivotal role in decision-making and in delivering value to shareholders.

Our Approach

“When it comes, however, a chemical sterilant will be one of the great innovations in the field of animal welfare, with worldwide applications and dramatic benefits”

Wayne Pacelle, President, CEO, Humane Society of the United States, The Humane Economy, 2016.

We at Thrivant Health share Mr. Pacelle’s view of the value such a tool will have on animal welfare. But the value goes beyond animal welfare. The newly evolved Sustainable Development Goals recognize more explicitly than ever before the need to tackle inequity and to provide health for all. Realistic solutions to problems that disproportionately burden poor communities are of particular interest, since health and educational improvements at this level typically enjoy returns many times the initial investment. The public health component of Thrivant Health’s business model is straight down the centerline of this movement. We are at the front end of developing an integrated One Health intervention that spans health sectors, enabling concurrent resolution of both human and veterinary issues related to dog overpopulation.
