When Blair was rescued by 600 team members, she was extremely weak and sick. She was eating garbage, and was sad and thirsty.

“She definitely used to be someone’s companion,” said her rescuer. “The way she came to us, desperate for love and affection ... She knew how to shake hands … it is so heartbreaking to know she had been abandoned. She is so adorable.”

But now Blair is a happy dog: she’s been rescued, fed a trial Cookie, and adopted into a loving home!

As a small, grassroots charity –

doing the work that billion-dollar drug companies have failed to do – we make every contribution go a long way.

Supporters like you make it all possible!

The Spay and Neuter Cookie, once completed, will be safe, one-dose, permanent birth control for dogs and cats.

It will have the potential to end the greatest cause of suffering that dogs and cats face: overpopulation.

With 5 new scientists on the team, we continue to make progress.

Our latest grassroots study is under way with over 30 rescued Pilot Pups!

Giving Tuesday is a day dedicated to good deeds and giving to those who need it most. We cannot thank you enough for your generosity. The human bond with dogs and cats is incredibly powerful … … and you’re living proof of that!

What we do and why we do it ...

At 600 Million Dogs, we’re working to develop a safe, inexpensive permanent birth control Cookie that only needs a one-time administration.

A Cookie that could be given just one time, and it will safely prevent reproduction for the rest of an animal’s life.

The millions of homeless dogs and cats killed each year need this.

The problem is that this type of birth control is still in the R&D stage, and the drug companies are not working on it.

We may be a small grassroots organization, but we're tackling this issue head-on. We are determined to develop the Spay and Neuter Cookie and solve the greatest crisis facing dogs and cats.

In short, we're working on a permanent solution to this global problem.

With our dedicated scientists working part-time, we've made important progress. But we need scientists working full-time to finish the job, and this is why we need your help.

If you would like to support our work, please make a tax-deductible gift of any amount.

Your gift will make a tangible impact ... and the animals will be forever grateful.
