Neutering involves removing the source of hormones that control reproduction and that determine the physical and behavioral characteristics that distinguish males and females. In dogs, this is done by surgically removing the testicles in males (castration) and the ovaries and uterus in females (spaying).
The primary purpose of neutering is to prevent unwanted reproduction. Every year, between 6-8 million pets are euthanized at animal shelters and veterinary hospitals because they are unwanted. We can stop this by neutering our pets. The optimal time to have your furry friend neutered is between 4-6 months of age.
