Spay versus Neuter—What’s the Difference?

Well-meaning pet owners often confuse spaying and neutering. Understanding the difference can help you appreciate the long-term benefits to your pet’s health and happiness.

  • Spay (i.e., ovariohysterectomy) — The spay surgery is the removal of the ovaries and uterus in a female pet.
  • Neuter (i.e., castration) — The neuter surgery is the removal of both of a male pet’s testicles. In large-breed adult dogs, the scrotum may also be removed to prevent postoperative complications.

Spay and Neuter Benefits for Pets

Any time your pet needs surgery, you naturally wonder if the benefits outweigh the surgical risks and recovery time. With spaying and neutering, the numerous positive results speak for themselves, including:

  • Preventing unwanted litters
  • Reducing or eliminating the risk for reproductive cancers (i.e., mammary, testicular, ovarian, uterine)
  • Eliminating the risk for reproductive emergencies, including pyometra (i.e., uterine infection), dystocia, and C-section
  • Eliminating heat cycles in female pets
  • Preventing or reducing hormone-related behaviors, including roaming, fighting, territorial aggression, and urine-marking, although training will be necessary if these behaviors are already established

When to Schedule your Pet’s Spay or Neuter Surgery

Your pet’s breed, lifestyle, and health will determine the ideal age for spaying or neutering. In general, we recommend the procedures before pets reach adulthood—around 1 to 2 years of age at the latest. While hormones are critical for proper development—especially in large- and giant-breed dogs—this must be carefully balanced with curbing or preventing hormone-related behaviors and accidental mating. Your Veterinary Medical Center of Indian River County veterinarian can help you determine the right time to spay or neuter your pet.
