Zinc Gluconate is a compound based on Zinc which is a natural ingredient in the body that offers a safe, permanent and virtually painless alternative to surgical castration.
Zeuterin consists of sterile water, Zinc gluconate, and the amino acid arginine and produces infertility in male dogs by chemical disruption of the testicle; it is intended as an alternative to surgical neutering. Before being allowed to administer Zeuterin, veterinarians must complete a five-hour course teaching them the correct location and manner to inject the drug. Properly administered, Zeuterin is considered to be 99.6% effective when given to dogs three to ten months of age. Outside of the United States it is also known by the trade name Esterilsol.
The drug could be delivered through an injection to the testis, now veterinarians can sterilize male dogs with ease and confidence. The drug is now approved by the FDA and available in the USA.
