Spaying and Neutering

A preventive and responsible choice

Spaying and neutering are common surgical procedures that provide significant health, behavioral, and welfare benefits for your pet, while contributing to responsible population control.

A long-term investment in health

Spaying and neutering are preventive measures that improve your companion's quality of life. With the right diet and regular activity, your dog or cat will stay healthy and will only experience beneficial changes.

Preventive benefits

Benefits of spaying and neutering

These procedures offer important health and behavioral advantages depending on your pet's sex.

For females

  • Reduced risk of mammary tumors: especially effective when performed before the first heat cycle; the risk of mammary cancer is significantly reduced.
  • Elimination of pyometra risk: a potentially fatal uterine infection. Spaying completely eliminates this risk.
  • No more heat cycles: no bleeding, vocalizing, or heat-related behaviors. Increased comfort for you and your pet.
  • Prevention of phantom pregnancy: some unspayed females experience this stressful syndrome after every cycle.

For males

  • Reduced urine marking: less territorial marking inside the home and during walks.
  • Fewer escapes and roaming: reduced drive to seek females in heat, so fewer accident risks.
  • Prevention of health conditions: eliminates the risk of testicular tumors and reduces prostate problems.
  • Reduction of hormone-driven aggression: decreased aggression toward other males (training also plays an important role).

Population control

Spaying and neutering prevent unwanted litters and actively contribute to combating animal overpopulation. By having your pet altered, you are participating in a responsible and ethical approach.

Recommended age

What is the ideal age?

The recommended age varies based on species, breed, size, and your pet's health status.

🐕

Dogs

  • Females: often recommended before the first heat cycle (6–8 months), depending on breed and size.
  • Large breeds: may need to wait for complete bone development before the procedure (up to 12–18 months).
  • Males: generally between 6 and 12 months, based on physical and behavioral maturity.
🐈

Cats

  • Females and males: commonly between 5 and 6 months.
  • Early-maturing breeds: some cats can be spayed or neutered as early as 4 months if there is a risk of early reproduction.
  • Indoor cats: spaying is still strongly recommended even for pets that never go outside, for its health benefits.

Special cases

Some veterinarians recommend waiting until the end of growth for large dog breeds to avoid negatively influencing bone development. Always consult your veterinarian for a personalized recommendation based on your pet's health, size, and temperament.

Before surgery

Pre-surgical preparation

Proper preparation ensures a successful procedure and your pet's safety.

1

Pre-operative visit

Complete physical exam, pre-anesthetic blood work performed in our on-site laboratory (kidney and liver function), evaluation of heat cycles in females, and discussion of the surgical protocol.

2

Fasting and instructions

No food for 8 to 12 hours before surgery to reduce the risk of vomiting under anesthesia. Water is generally allowed until 2–3 hours before. Please inform us of any medications your pet takes.

3

Practical arrangements

Drop your pet off in the morning and pick them up in the afternoon. Ensure comfortable, secure transport. Plan to be home with your pet for 1 to 2 days after surgery.

The procedure

How the procedure unfolds

Your pet is in good hands; every step is performed with care and precision.

General anesthesia
  • Sedation and IV catheter: venous access is established, followed by intubation and maintenance on gas anesthesia for a smooth recovery.
  • Continuous monitoring: heart rate, oxygen saturation, and blood pressure are monitored throughout the procedure.
Surgery
  • Female: removal of the ovaries (ovariectomy) or ovaries + uterus through a small abdominal or flank incision, carefully sutured.
  • Male: removal of the testicles through a scrotal or pre-scrotal incision. Generally shorter and less invasive than the female procedure.
Recovery
  • Multimodal pain control: injections during surgery and tablets to administer at home. Your pet should not be in pain.
  • Monitored wake-up: a technician stays with your pet until they are sufficiently conscious and stable.
After surgery

Post-operative care

Home care is essential for optimal recovery.

To do

  • Settle your pet in a quiet, comfortable spot, away from drafts
  • Inspect the incision daily (redness, swelling, or discharge = call the clinic immediately)
  • Use the e-collar or post-op body suit to prevent licking
  • Enforce strict rest the first 2–3 days: no jumping, no intense play
  • For dogs: short leash walks for bathroom needs only, gradual return to activity
  • For cats: keep indoors until fully healed (10–14 days)
  • Attend the follow-up appointment (7–10 days post-surgery) for suture check or removal

To avoid

  • Allowing furniture jumping or stair climbing for 10–14 days
  • Removing the e-collar without veterinary advice, even if the pet seems unbothered
  • Ignoring a wound that bleeds, oozes, or appears to be opening
  • Giving human pain medications (Tylenol, Advil) which are toxic to animals
What changes

Expected changes after the procedure

Spaying and neutering bring some physiological and behavioral changes, all manageable with the right adjustments.

⚖️Metabolism and weight

Basal metabolism may decrease by 10–30%. Monitor weight regularly, switch to food formulated for altered pets, maintain daily exercise, and reduce treats.

🧠Behavior

Females: end of heat cycles and hormonal stress. Males: gradual reduction of marking, roaming, and hormone-driven aggression. Long-established habits may still require behavioral training.

❤️Health

Reduced risk of mammary, uterine, testicular, and prostate conditions. Potentially longer life expectancy. Some spayed females may experience urinary incontinence (rare); report this to your veterinarian.

Myths and facts

Common misconceptions

Let's clear up some widespread beliefs about spaying and neutering.

"My pet needs to have a litter before being spayed"

Reality: False. There is no scientific evidence supporting this belief. On the contrary, spaying before the first heat cycle significantly reduces the risk of mammary tumors.

"Spaying or neutering will completely change my pet's personality"

Reality: False. These procedures reduce hormone-driven behaviors (marking, roaming, aggression) but do not change your pet's core personality. They will simply be calmer and more balanced.

"My pet will inevitably gain weight after being altered"

Reality: Not automatically. Energy needs do decrease somewhat, but with appropriate food and regular exercise, your pet can maintain a healthy weight without difficulty.

"Surgery is too risky for a young, healthy animal"

Reality: Spaying and neutering are among the most commonly performed procedures in veterinary medicine. With pre-anesthetic bloodwork and a tailored protocol, risks are very low in healthy animals.

"A neutered male loses his guarding instinct"

Reality: False. Neutering reduces hormone-related territorial behaviors but does not eliminate natural vigilance and protective instincts. A neutered dog remains an excellent companion and watchdog.

FAQ

Frequently asked questions

At what age should I have my cat or dog spayed or neutered?
For cats, between 5 and 6 months is recommended. For dogs, it depends on breed and size: small breeds can generally be altered around 6 months, while large breeds may need to wait until 12–18 months for complete bone development. Consult your veterinarian for a personalized recommendation.
My female dog is in heat: can she still be spayed?
Technically possible, but generally not recommended because tissues are more vascularized during heat, slightly increasing bleeding risk. It's preferable to wait until after the cycle ends (about 3 weeks after heat). Discuss with your veterinarian based on the urgency of your situation.
How long is the recovery period?
Most pets return to normal activity within 10 to 14 days. The first 2–3 days require strict rest. Skin healing takes 10–14 days. Internal healing takes longer (about 4–6 weeks); avoid intense activities during this period.
Does my pet need to wear the e-collar all the time?
Yes, until full healing (typically 10–14 days). Even if your pet seems to ignore the incision, a single lick can introduce bacteria and compromise healing. Alternatives exist: post-op body suit, specialized bandage. Ask your veterinarian what works best for your pet.
What warning signs should I watch for after surgery?
Contact the clinic immediately if you notice: active bleeding or heavy discharge from the wound, significant swelling or worsening redness, open wound or loose sutures, fever, excessive lethargy, or refusal to eat for more than 24 hours after surgery, persistent vomiting, or breathing difficulties.
What is the difference between an ovariectomy and an ovariohysterectomy?
An ovariectomy removes only the ovaries; an ovariohysterectomy removes the ovaries AND the uterus. Both methods effectively prevent pregnancy and hormonal disorders. Ovariectomy alone is increasingly used as it is less invasive while providing the same long-term benefits when the uterus is healthy. Your veterinarian will choose the most appropriate approach for your pet.
