Well, this is a bit of a surprise. A newly published study found that dogs that are neutered may actually have a slightly shorter lifespan than intact dogs. This finding was based on a recent analysis of available clinical records in Australia. These records, collated by VetCompass Australia, comprised 3,085 intact and 4,100 neutered Rottweilers from July 1994 to June 2021. The analysis found that dogs that were neutered before one year of age had a shortened lifespan of one-and-a-half years in males and one year in females when compared to their intact counterparts.

The analysis also found similar results in dogs that were desexed β€” neutered β€” before the age of four-and-a-half years.

β€œMost other studies have found that neutering dogs increases their longevity but ours is one of the first that went against that,” the study’s lead author, veterinarian Carolynne JoonΓ¨, said in a statement. Dr JoonΓ¨ is a senior lecturer at James Cook University in theriogenology (a specialist in animal reproduction) and her current research focuses on fertility control in horses.
