How Spaying and Neutering Protect Your Pet’s Health

At Stanton Pet Hospital in Stanton, California, we know that deciding to spay or neuter your pet is a big step—and one that goes far beyond preventing unwanted litters. These common surgical procedures offer wide-ranging benefits for your pet’s health, behavior, and overall well-being.

This guide explains why spaying and neutering is one of the most effective preventive care choices you can make—not just for population control, but for a longer, healthier, and more peaceful life for your dog or cat.

What Does It Mean to Spay or Neuter a Pet?

  • Spaying is the surgical removal of a female animal’s ovaries and uterus, preventing pregnancy and eliminating heat cycles.
  • Neutering (or castration) involves removing the testicles of a male animal, preventing reproduction and reducing hormone-driven behaviors.

While these are routine procedures, their impact on your pet’s future health is anything but routine.

More Than Population Control: Why It Matters

While preventing unplanned litters is a major reason to spay or neuter, the benefits don’t stop there. These procedures also reduce your pet’s risk for serious diseases, improve behavior, and make life easier for both pets and their people.

Health Benefits of Spaying and Neutering

In Female Pets:

  • Eliminates the risk of pyometra, a life-threatening uterine infection.

  • Reduces the risk of mammary cancer—especially when done before the first heat cycle.
  • Prevents uterine and ovarian cancers.

In Male Pets:

  • Eliminates the risk of testicular cancer.
  • Reduces prostate issues, including infections and enlargement.
  • Lowers the risk of hernias and perianal tumors, particularly in older, unneutered dogs.

Overall Lifespan:

Studies show that spayed and neutered pets tend to live longer, healthier lives thanks to the prevention of these serious health issues.

Behavioral Benefits You’ll Notice

Spaying and neutering can reduce or eliminate many unwanted behaviors tied to mating instincts.

Neutered Male Pets May Show:

  • Less roaming, reducing their risk of injury or getting lost
  • Reduced marking behavior and urine spraying
  • Decreased mounting and dominance-related aggression

Spayed Female Pets May Experience:

  • No more vocalizing or behavioral shifts during heat cycles
  • Less attraction of unwanted attention from intact male animals
  • More consistent behavior and comfort year-round

Benefits for You—and the Community

  • No surprise litters: Even indoor pets can escape or encounter unneutered animals.
  • Lower risk of strays: Fewer litters means fewer unwanted animals in shelters.
  • Less stress at home: Without heat cycles or hormone-driven behavior, both you and your pet will enjoy a calmer, more manageable routine.

When Should You Spay or Neuter Your Pet?

Dogs

Most dogs are spayed or neutered between 6–12 months, but the right timing depends on your dog’s breed, size, and health.
 AAHA’s canine life stage guide can help you understand your dog’s needs at every age.

Cats

Kittens can be safely spayed or neutered as early as 8 weeks, though most vets recommend it between 4–6 months.

Senior Pets

Older pets can still benefit from these surgeries, but may need extra pre-surgical testing. We’ll help assess risk and benefits for your individual pet.

Addressing Safety and Common Concerns

Are There Risks?

As with any surgery, there is a small risk of anesthesia or post-op complications—but these are minimized with:

  • Pre-surgical exams and bloodwork
  • Sterile surgical protocols
  • Close post-operative monitoring and guidance

Concerns About Joint Health and Weight Gain

  • Large-breed dogs may have increased joint health risks if altered too early. We’ll discuss timing based on your pet’s growth pattern.
  • Weight gain can occur after surgery—but it’s manageable with regular exercise and a healthy diet.

Common Myths, Debunked

“My pet will get lazy or fat.”

False. Changes in activity are more often linked to decreased exercise and overfeeding—not the surgery itself.

“Spaying or neutering will change my pet’s personality.”

Also false. Your pet will still be the same loving companion, just without hormone-driven behaviors.

“It’s unnecessary if I don’t plan to breed.”

Even pets that aren’t around others can develop reproductive diseases or behavioral issues. Spaying or neutering offers lifelong benefits, no matter the social situation.
