Chilean Scientists Innovate Reversible Dog Neutering Vaccine

The new injection offers a non-surgical, reversible alternative for pet sterilization, potentially transforming animal population control.

Findley, a Chilean terrier, is among the first dogs to be neutered using the Egalitte vaccine, avoiding surgery.
Developed by University of Chile's Leonardo Saenz, the vaccine works by blocking reproductive hormones.
The procedure is simple, requiring only an injection, and costs approximately $54.
Both male and female dogs can receive the vaccine, pending a veterinarian's evaluation and prescription.
The vaccine's simplicity and reversibility could allow for broader and less invasive animal population control.
