Stop spaying and neutering so young in age!!
Preventing unwanted litters is a goal we all share—but it's time to rethink the surgical approach. Hysterectomies and vasectomies, which preserve hormonal balance, can safely be performed as early as 8 weeks of age, making dogs sterile without disrupting their natural hormones.
In this study, researchers looked at whether the age at which dogs were spayed or neutered, meaning how long they were exposed to their natural s*x hormones, affected how healthy they were in old age. They studied a group of long-lived pet dogs to learn what helps dogs live longer, healthier lives. Dogs with the fewest age-related health problems were considered the most “robust.”
The results showed that both male and female dogs who kept their hormones longer (i.e., were spayed or neutered later) were 3 to 10 times more likely to be healthy in old age compared to those altered earlier. Once hormone exposure and age were taken into account, there was no difference in old-age health between males and females.
This study highlights how important s*x hormones may be for staying healthy later in life and shows that early-life decisions—like when to spay or neuter—can have long-term effects on health.
