Dog Birth Control - ChemSpay

by Dr. Chris

July 24, 2011 A scientist is claiming to have invented dog birth control, a way to sterilize dogs without surgery. The drug's name is Chemspay. If it actually works it could solve the pet overpopulation problem. The inventor, Dr. Loretta Mayer was working with mice to develop animal models of human disease when her team stumbled upon their finding of dog birth control.

There have been others that have attempted non-surgical sterilization of dogs in the past but those have not really performed as promised. And even if this method of dog birth control works, it still would not be available for several years, and still has to be approved as safe by the federal government.

The drug’s name is Chemspay. It is given to dogs orally or by injection. It has been tested for 4 years so far on dogs. Chemspay reduces the number of eggs in the ovaries, making dogs sterile.

Dr. Mayer hopes to have FDA trials going in about 2 years.

Other Attempts at Dog Birth Control

Neutersol was approved for use to sterilze male dogs by injection. Neutersol was taken off the market in 2005 and is not available in the US. GonaCon is a deer contraceptive that shows promise. GonaCon is being studied to see if it could be used in dogs or cats.
