Welcome to the Spay FIRST non-surgical sterilization page. This page is here to provide information on products and compounds that make it possible to prevent litters when traditional spay or neutering surgeries are out of reach due to poverty, distance and other challenges. Watch as this page grows!
Surgical spaying and neutering is safe and permanent; this page is not intended to highlight alternatives to standard veterinary procedures where these procedures are affordable and can be provided for the majority of dogs and cats.
This site is intended to provide information about options for the millions of unwanted animals for whom surgical sterilization is out of range due to a lack of funding, clinics, and human resources (surgeons) and for whom an unwanted litter can mean starvation and death for mom and her litter. Not a single continent is untouched by this problem.
Estimates vary widely, but at least 400 million dogs and roughly the same number of cats exist worldwide and around 300 million (three quarters) of each are unwanted. Most live in nations in which animal welfare laws do not exist or cannot be enforced; many are chased away or beaten for simply begging for a scrap of food. Non-surgical options will prevent untold suffering for just pennies each.
The average life of a street dog is roughly three years. Non-surgical sterilization is the only way to develop humane population control programs in impoverished places and to do so in a big enough way to make a difference.
Additionally, tens of thousands of people in developing nations die of rabies each year and over 98 percent of cases come from dog bites. Street dogs are not seen as a friend in need; they are despised as a dangerous vector; many become targets of cruel killing campaigns. Stopping new generations of street dogs from being born is vital to wiping out rabies while placing animal welfare into the forefront.
Calcium chloride: a video for veterinarians. This video shows the use of compounded calcium chloride dihydrate for non-surgical castration of male dogs. Use of compounded drugs must be carried out in accordance with state or province regulations and with a valid Veterinary Client Patient Relationship (VCPR) in place. Technique modified from earlier research by Kuladip Jana, Prabhat K Samanta and Raffaella Leoci.
Non-surgical sterilization can stop the suffering. We can turn fear into compassion and make a lasting difference for animals and the communities they live in.
