About SBPA

SBPA (Sociedad Benefactora y Protección Animal de San Carlos, A.C.) is a bi-cultural not-for-profit volunteer organization with a decades long history in San Carlos, Sonora, Mexico. SBPA’s parent organization, SBPA Services, Inc., incorporated in 1995, is a 501(C)3 organization that is headquartered in Tucson, Arizona.

The mission of both SBPA Services, Inc. and its south-of-the-border non-profit, SBPA de San Carlos, is to protect animals and to alleviate the suffering created by their uncontrolled population growth. This goal is realized through a multi-faceted program that includes free spay and neuter clinics and certificates; and distribution of educational materials that promote responsible pet ownership.

In Mexico there are around 23 million dogs and cats. While 5.4 million of these animals live in homes, the remaining 70% live on the streets.


Main Reasons to Spay or Neuter

The sterilization of all dogs and cats greatly helps to alleviate the suffering of animals as well as the spread of diseases to humans.

Reduce Stray Population

Unwanted litters needlessly suffer being born on the streets without proper food or care, enduring mistreatment, disease and starvation.

Better Temperament

Improve animal behavior by making them calm and gentle, reducing fighting and wandering away.

Reduce Spread of Diseases

Controlling the population reduces the risk of flea and tick borne diseases to humans such as rickettsia, lyme disease and gastrointestinal parasites.

Healthier Life for Animals

Sterilizing your pet eliminates many cancers amongst animals which leads to suffering and unexpected financial burden for the family. It also will result in less spraying and marking.
