Building Strong Foundations: How Proper Spay/Neuter Timing Supports Canine Longevity

Video On Proper Spay/Neuter Timing

Protecting Health, Structure, and Longevity Through Science


At Southernwind Kennels, we care deeply about the long-term health and happiness of every puppy we raise. That’s why our purchase contract clearly states that any dog sold under Limited AKC Registration is not to be bred and must be spayed or neutered at no less than 20 months of age.


This is not simply a rule —Proper Spay/Neuter Timing it’s a decision based on decades of experience and solid scientific evidence showing that spaying or neutering too early can have serious effects on your dog’s physical and emotional development.


Why Timing Matters


For many years, veterinarians recommended spaying or neutering dogs at around six months of age. But modern research from UC Davis, AVMA, and other veterinary institutions reveals that this “one-size-fits-all” timing may not be ideal — especially for large-breed dogs like the German Shepherd.

What Hormones Actually Do


  • Closing the growth plates in bones (ensuring correct structure)

  • Strengthening ligaments and tendons

  • Regulating metabolism and muscle tone

  • Supporting immune balance and mental stability

When these hormones are removed too early, growth plates remain open longer, causing unbalanced bone growth and joint stress.

That’s why large breeds neutered before maturity often face higher risks of orthopedic problems later in life.


Proven Scientific Findings, Proper Spay/Neuter Timing


According to UC Davis Veterinary School studies on over 35 breeds:

  • Joint Disorders: Dogs neutered before 12 months — especially large breeds — have significantly higher rates of hip dysplasia, elbow dysplasia, and cranial cruciate ligament tears.

  • Cancer Risks: Certain cancers such as lymphoma, mast cell tumors, and hemangiosarcoma appear more frequently in dogs neutered too early.

  • Urinary Incontinence: Spaying females before maturity can lead to hormone-related urinary leakage.

  • Metabolic Changes: Early gonadectomy (spay/neuter) slows metabolism, increasing risk of weight gain, obesity, and related health issues.


The AVMA now advises veterinarians to consider breed, sex, and size before recommending the age of sterilization — moving away from the outdated six-month rule.

Why Southernwind Chooses 20 Months


Waiting until your dog is 20 months or older before spaying or neutering allows:


  1. Full Skeletal Maturity — the body finishes developing naturally, reducing orthopedic stress.

  2. Stronger Muscles and Ligaments — essential for joint stability and protection.

  3. Balanced Hormonal Development — promoting calm confidence instead of fear or anxiety.

  4. Reduced Long-Term Health Risks — especially in large and working breeds.

This policy ensures your dog enjoys a stronger body, healthier joints, and longer active life, while still preventing unwanted litters and maintaining breed integrity.



Common Questions


Isn’t spaying early better for preventing mammary cancer?

In some small breeds, early spay may reduce mammary tumor risk — but in large breeds, this benefit is outweighed by the higher risk of orthopedic and other hormone-related issues. Each case should be discussed with your veterinarian.


Will waiting make my dog harder to handle?

Not if you provide structure, training, and consistency. Hormones don’t create bad behavior — lack of guidance does.


Can I use alternatives?

Some owners explore vasectomy or ovary-sparing spay procedures, which prevent reproduction but allow hormone function to continue. Ask your veterinarian about these options.


The Science Is Clear


  • The UC Davis 2024 updated study on 40 breeds emphasizes that timing should depend on breed and size.

  • The AVMA now encourages individualized recommendations, not a universal early-age approach.

  • Delaying sterilization helps reduce joint disease, certain cancers, and metabolic imbalances — giving your dog a healthier, more natural development.


In Summary


At Southernwind, we’ve seen firsthand how waiting until 20 months before sterilization supports healthier, stronger, and more balanced dogs.

It’s part of our mission to combine science, ethics, and experience for the well-being of every puppy we place.
