We all want to prevent unwanted litters. Hysterectomies and vasectomies offer early, safe sterilization, starting at 8 weeks, while preserving the natural hormones dogs need.
New Peer-reviewed study shows s*x hormones (like estrogen and testosterone) help the spine and discs develop properly. Removing these hormones from dogs too early can affect bone growth and disc strength, making the spine more vulnerable.
Spaying/neutering early (before 12 months) greatly increased the risk of slipped discs in French Bulldogs.
• For males:
o Early-neutered males were almost twice as likely to develop IVDH compared to intact males.
o Neutering after 12 months actually lowered their risk.
• For females:
o The effect was even stronger.
o Spayed females were about 5 times more likely to have IVDH than intact females.
o If spayed before 12 months, they were almost 10 times more likely to develop the problem.
The age you choose to spay or neuter a French Bulldog can have a major impact on their long-term spine health.
