Puerto Rico Animal Sterilization

If you need financial assistance for your owned animal to be spay or neutered, we first suggest you contact the groups closest to you, listed below.   Most will offer assistance and suggestions of nearby discounted clinics for sterilization.  Our Mission is to help un-owned or street animals.

If you need help with a rescued street animal please read our Rescue a Puerto Rican Animal Page.  Defensa Animal de Rincon helps street animals rescued anywhere in Puerto Rico – we do not assist owned animals but these others might.
