Overview

• 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.
