The Essential Guide to Spaying and Neutering Your Pet

Why Spaying or Neutering Is More Than Just Population Control

Spaying (for females) and neutering (for males) are routine surgical procedures with powerful health and behavioral benefits. While most people know these surgeries help prevent unwanted litters, many are unaware of how deeply they contribute to your pet’s lifelong wellness.

At North Waterloo Veterinary Hospital, our team is here to ensure your pet’s experience is safe, comfortable, and personalized—from pre-op exams to full post-op care.

Learn more about the broader impact of spaying and neutering from the AAHA’s Spay/Neuter Resources and ASPCA’s guide.

Health Benefits of Spaying and Neutering

For Female Pets

  • Prevents Pyometra
    Pyometra is a painful and often life-threatening uterine infection. Spaying removes the uterus, completely eliminating the risk. Read more about pyometra in dogs from Cornell University.
  • Reduces Mammary Tumors
    Spaying before a pet’s first heat cycle can reduce the risk of mammary cancer by up to 90%.

For Male Pets

  • Eliminates Testicular Cancer Risk
    Neutering removes the testicles, preventing testicular cancer entirely.
  • Lowers Prostate Issues
    Neutered pets have fewer prostate complications and infections.
  • Improves Behavior
    Neutering can decrease hormone-driven behaviors like roaming, mounting, urine marking, and aggression.

Behavioral Benefits: What to Expect

After surgery, many pets show:

  • Reduced desire to roam (decreasing risk of getting lost)
  • Less hormonal-driven aggression
  • No more heat cycles or unwanted behaviors like vocalizing or urine spraying

Important note: Spaying or neutering does not cause laziness or weight gain. Activity levels, age, and diet are the true influencers of pet weight. Monitor your pet’s life stages and adjust care as they age.

When Should You Spay or Neuter Your Pet?

There is no one-size-fits-all answer. The right time depends on your pet’s:

  • Species and breed
  • Size and growth rate
  • Lifestyle and behavior
  • Health history

In general:

  • Cats and small-breed dogs are often spayed or neutered around 5–6 months.
  • Large-breed dogs may benefit from waiting longer to support joint development.

Our veterinarians tailor recommendations based on your pet’s specific needs, with an emphasis on long-term health.
