Animal Birth Control Clinic

Due to the retirement of one of our veteirnarians,   prescription medications such as Bravecto and Tri-Heart Plus will only be available on our surgery days which are Tuesday and Wednesdays. These services will be available on these days from 8:30 to 5:30. We are sorry for any inconvenience.               

Think About It

There are a hundred million dogs and cats in America. We cuddle them, talk to them, make them part of the family.

Every year we buy them $5 billion worth of food, not to mention collars, bowls, flea spray, vaccinations and little pink sweaters. We love our pets.

Except of course when we have to move, or get tired of walking them, or sick of paying the vet bills. Then we abandon them.

By the millions!




NOPO was born out of a strong-willed local 501(c)3 organization formed as The Lawton (OK) United Volunteers for Animal Birth Control to combat a serious pet overpopulation problem in a military town located in one of the worst puppy mill states in the nation. We are pioneers in this battle with years of accomplishments and passion for the cause.
In 1985, undaunted by heavy opposition from local veterinarians, and the Oklahoma State Board of Veterinary Medical Examiners, which ultimately resulted in a Federal Trade Commission investigation, the Animal Birth Control Clinic opened its doors. This non-profit, low-cost neuter/spay facility has neutered and spayed tens of thousands of pets and ultimately saved millions of lives. No pet owner is turned away regardless of his or her ability to pay.

In 1989, the FTC charged Oklahoma veterinarians with injuring consumers by illegally restricting competition.

No administrative salaries are paid at NOPO, however, the Animal Birth Control Clinic has paid veterinarians and staff.

In 1991, the IRS granted our request to change our name to The National Organization to End Pet Overpopulation. Inasmuch as we serve a large military clientele, the pets we neuter and spay can be found in communities throughout the world.

We have never stopped battling for "litter" laws both statewide and locally and were instrumental in the passage of a groundbreaking city ordinance which seriously restricts and taxes pet breeding.

End Pet Overpopulation


For decades, good people have fought for bigger and better shelters and more adoptions.


Without slowing the influx of millions of animal births, population control is impossible.


Always have your own pets neutered and spayed. It is worth the effort.

Vaccinations are available on Tuesdays and Wednesdays from 8:30 AM to 5:30 PM


 No Appointment Necessary!
