Spay and Neuter in Dogs & Cats: Decisions That Support Lifelong Wellness

Spay and neuter decisions in dogs & Cats are not one-size-fits-all and should be made with long-term health in mind. From a holistic perspective, preserving sex hormones through proper timing and alternative procedures can support healthier joints, stronger immunity, balanced metabolism, and emotional stability. Our approach prioritizes hormone-sparing options whenever possible to protect the whole dog, not just prevent reproduction.

Per Dr. Judy Morgan’s: antibiotics are absolutely not indicated in a clean surgical spay.

If the sutures do not dissolve use a warm compress multiple times a day. Eventually they will push it out. Topical antibiotic cream or colloidial silver are recommended.

Why Hormones Matter in Dogs & Cats: Rethinking Spay and Neuter

Spay and Neuter in Dogs and Cats: A Holistic Perspective

Spaying and neutering are often presented as routine procedures for both dogs and cats, but from a holistic standpoint, the timing and type of sterilization matter greatly. Sex hormones play a critical role in physical development, immune health, joint integrity, metabolism, and emotional stability. Removing them too early or unnecessarily can have long-term consequences for a pet’s overall health and longevity.

Why We Do Not Recommend Early Neutering

We do not recommend neutering male dogs before 24 months of age, as testosterone is essential for proper growth plate closure, muscle development, bone density, and neurological maturity. Early neutering in dogs has been associated with increased risks of orthopedic issues such as cruciate ligament tears and hip dysplasia, certain cancers, obesity, thyroid disease, and behavioral changes including fearfulness and anxiety.

Cats mature more quickly than dogs, but hormones still play an important role in development and overall health. While the timeline may differ, the principle remains the same — removing hormones too early can impact metabolic health, weight regulation, and long-term resilience.

Allowing pets to fully mature before surgical intervention supports healthier development, stronger immune function, and more balanced behavior.

Why We Prefer Vasectomy Over Traditional Neuter

When sterilization is desired for male dogs, we strongly prefer vasectomy over traditional neuter. A vasectomy renders the dog sterile while preserving the testes and natural hormone production.

This approach:

  • Prevents reproduction without removing vital hormones
  • Maintains healthy testosterone levels
  • Supports joint, muscle, and metabolic health
  • Reduces risk of hormone-related diseases
  • Preserves natural confidence and emotional balance


A vasectomy offers population control without sacrificing the long-term health benefits of intact hormones, making it a more biologically respectful option.

At this time, vasectomy is less commonly performed in cats and may not be widely available, but the concept of preserving hormones where possible still applies.

Female Dogs and Cats: Ovary-Sparing Spay

For female dogs, we recommend an ovary-sparing spay (OSS), ideally performed after the first heat cycle. This procedure removes the uterus while leaving the ovaries intact, allowing the dog to retain estrogen and other critical hormones.

For cats, ovary-sparing procedures may be less commonly offered, but delaying early sterilization when safely possible and working with a knowledgeable veterinarian can still support better long-term outcomes.

Allowing a female to go through at least one heat supports:

  • Proper bone and joint development
  • Cardiovascular and metabolic health
  • Urinary and reproductive tissue strength
  • Emotional and neurological maturity


Preserving ovarian hormones helps reduce the risk of orthopedic disease, urinary incontinence, and certain endocrine disorders that are more common in early-spayed animals.

If your female dog is frequently exposed to intact males (such as in multi-dog homes, dog parks, or daycare settings), an ovary-sparing spay may not be the safest option due to the risk of mounting-related injury.

A Thoughtful, Individualized Approach

There is no one-size-fits-all answer when it comes to spay and neuter decisions in dogs and cats. Breed, size, species, health history, lifestyle, and environment all matter. Cats, for example, have different reproductive behaviors and population risks than dogs, which must be considered carefully.

Our recommendations are rooted in long-term wellness, not convenience or outdated norms.

Whenever possible, we encourage pet parents to work with a veterinarian who is knowledgeable about delayed sterilization, hormone-preserving procedures, and holistic health outcomes.

Spay and neuter decisions should support the whole animal — not just population control.

FAQ

Frequently asked questions Regarding Spay and Neutering for cats & dogs

From a health-first perspective, timing matters. Dogs should generally be allowed to fully mature before sterilization, which often means waiting until at least 18–24 months depending on breed and size. For females, allowing at least one heat cycle supports proper development. Cats mature faster, but hormone preservation and individualized decisions should still be considered rather than routine early procedures.

 

Early spay and neuter can impact joint development, hormone balance, metabolism, and behavior. Studies have linked early sterilization to increased risks of orthopedic issues, certain cancers, weight gain, urinary incontinence, and anxiety-related behaviors. Preserving hormones during key growth stages supports long-term health and stability.

Yes. Hormone-preserving options like vasectomy for males and ovary-sparing spay for females prevent reproduction while maintaining natural hormone production. These alternatives support overall health, including joints, immune function, and emotional balance, while still addressing population control responsibly.

Recommended Products to Support Dogs After Spay and Neuter

This is what we would do: 

  1. Limit activity for 10-14 days to promote healing. 
  2. Monitor the surgical site for redness and swelliing.
  3. We would not spay before 24 months and we would do ovary sparing spay only if our dog was not exposed to other male dogs at home, dog parks or day care centers. For male dogs we would do a vasectomy as opposed to neutering. 
  4. Your pet may have urinary incontinence after sterilization.
  5. Dr. Judy Morgan says that antibiotics are not needed for a clean surgical spay. If you feel you need something for pain, see our pain management page. CBD Dog Health Ease (15% coupon: SAVINGPETS) and CBD Dog Health Ease for Cats (15% coupon: SAVINGPETS) can help ease pain and swelling.
  6. A fresh species appropriate raw or gently cooked diet helps the body process medications and inflammation more efficiently than ultra processed food (kibble).
  7. Offer bone broth to ensure your pet is adequately hydrated.
  8. Omega-3s from a clean marine source can help modulate and support healing. We recommend Adored Beast Potent Sea Omega-3 Oil and Four Leaf Rover Safe Sea Oil 10% coupon off of full priced items with coupon: SAVING-PETS).
