Spaying or neutering your dog before they’re fully developed can negatively impact their growth, hormones, and long-term health. While it might seem convenient to “get it out of the way,” here’s what the research says:
1️⃣ Joint Development Risks: Studies show that dogs spayed/neutered before 12 months have a higher risk of hip dysplasia, torn ACLs, and arthritis. Their bones keep growing unnaturally, increasing the chance of injury.
2️⃣ Cancer Concerns: Certain cancers, like hemangiosarcoma and osteosarcoma, are 4X more likely in dogs spayed/neutered early.
3️⃣ Behavioral Shifts: Hormones help regulate confidence and self-control. Early removal can lead to increased fearfulness or even aggression.
4️⃣ Longevity Impact: Research from the UC Davis School of Veterinary Medicine reveals that early alteration can reduce lifespan by 1-2 years.
I advocate for timing it right to protect your pup’s health. Waiting until their growth plates close (12-18 months for most breeds) ensures their body develops as nature intended.
Your pup’s health isn’t a shortcut—it’s a long-term investment in their quality of life.
