Introduction: Why the topic of "castration in dogs" is so important

Hardly any topic causes as much discussion among dog owners as the Castration in dogs. Some see it as a sensible precaution against unwanted offspring and hormone-related problems, while others fear health risks or changes in behavior.

As a veterinarian, I see firsthand in my practice how uncertain many dog owners are. Should you have your dog neutered? When is the right time? And what alternatives are there?

In this article, based on veterinary experience and current scientific findings, I explain everything you as a dog owner should know about castration.

What does "castration in dogs" mean?

Under a castration This refers to the surgical removal of the sex glands.

• At the male dogs will the testicles removed.
• At the bitch are usually ovaries (and sometimes the uterus) removed.

The aim of the operation is to permanently stop hormone production in order to prevent reproduction and to influence certain behavioral or health problems.

---

Difference between castration and sterilization

A common misconception: Many dog owners confuse castration with Sterilisation.

• Sterilization: Only the vas deferens or fallopian tubes are severed – hormone production is preserved. The dog is infertile, but its hormonal behavior remains unchanged.
• Castration: The gonads are removed, which also eliminates the sex hormones (testosterone or estrogen/progesterone).

In veterinary practice in Germany, dogs are treated with almost exclusively neutered, because this is the only way to change hormonal influences on behavior and health.

Different forms of spaying in female dogs – advantages and disadvantages

Not every spaying procedure for a female dog is the same. Depending on the medical indication, age, and individual situation, different approaches are used. Surgical methods That's in question. As a veterinarian, it's important to me to explain the differences clearly to dog owners so that they can work with us to decide... best possible decision can meet.

🩺 1. Ovariectomy (removal of the ovaries)

At the Ovariectomy become only the ovaries (Ovaries removed). The uterus remains in the dog's body but is hormonally inactive, as the control via the ovaries is no longer maintained. This method is the standard in many European countries – especially in the Netherlands, Belgium, and France. Standard method.

✅ Advantages of oophorectomy:

• Minor procedure: The incision is shorter, the operation takes less time, and the recovery time is often shorter.
• Reduced surgical risks: Since the uterus is not removed, the risk of bleeding or injury to other organs is lower.
• Same result: Hormone production is completely stopped, and the female dog can no longer go into heat.
• Less pain after surgery: The smaller surgical wound often makes aftercare easier.

⚠️ Disadvantages of oophorectomy:

• Only makes sense if the uterus is healthy: If the uterus is already pathologically altered (e.g., cysts, thickening of the mucous membrane), it should also be removed.
• Later pyometra is possible if remnants of the ovaries remain: In rare cases, a so-called Stump pyometra This occurs when tiny remnants of hormone-producing tissue remain.

👉 Conclusion from practical experience:
For young, healthy female dogs without uterine abnormalities, ovariectomy is the gentlest and recommended method. It is the standard in many modern practices and clinics, unless there are medical reasons against it.

---

🩺 2. Ovariohysterectomy (removal of ovaries and uterus)

The Ovariohysterectomy This is the classic form of castration, which is still the most frequently performed method in Germany. In this procedure, Ovaries and uterus completely removed.

✅ Advantages of ovariohysterectomy:

• No risk of uterine diseases: Since the uterus is completely removed, pyometra (uterine infection) can no longer develop.
• Useful for older female dogs: Especially if hormonal changes or inflammation are already present.
• Prevents uterine tumors or cysts: Even rare but possible changes to the uterus are ruled out.

⚠️ Disadvantages of ovariohysterectomy:

• Major surgical procedure: The operation takes longer, the abdominal incision is larger, and the wound healing takes a little more time.
• Slightly higher risk during anesthesia: Especially in large or older female dogs.
• Longer recovery period: More rest is needed, sometimes longer pain therapy.

👉 Conclusion from practical experience:
Ovariohysterectomy is the safest choice for older female dogs or in cases of pathological findings (e.g., uterine changes). It is also advisable if the owners want to be sure that there is no longer a risk of future uterine disease.

---

🩺 3. Minimally invasive (laparoscopic) castration

The laparoscopic castration This is the most modern and gentle method. A camera and fine surgical instruments are inserted through two to three very small incisions in the abdominal wall. The ovaries (and sometimes the uterus) are removed under direct visualization with minimal trauma.

✅ Advantages of the laparoscopic method:

• Very small wounds: Barely visible scars, low risk of wound healing disorders.
• Rapid recovery: Many female dogs are already lively again the next day.
• Less pain: Thanks to the minimally invasive procedure and modern anesthesia techniques, there are significantly fewer postoperative complaints.
• Best overview for the surgeon: The camera provides perfect visibility of the abdominal cavity, which increases precision.

⚠️ Disadvantages of the laparoscopic method:

• Higher costs: Special equipment and longer preparation lead to higher prices (usually €700–1,000).
• Not suitable for all female dogs: In cases of severely enlarged uterus or tumors, the classic method must be used.
• Only to be performed by experienced surgeons: Requires special training and equipment.

👉 Conclusion from practical experience:
If the technical possibilities are available, the laparoscopic castration the gentlest form – especially for young, healthy female dogs. The additional costs are often worthwhile due to faster recovery and fewer complications.

🩺 4. Early spaying vs. late spaying in female dogs

Another important difference concerns the time castration – and here too there are advantages and disadvantages.

Early castration (before the first heat):

• Advantages: Almost complete protection against mammary tumors, no heat cycles, no risk of unwanted pregnancy.
• Disadvantages: Possible impact on bone growth (larger, slimmer dogs), sometimes increased risk of incontinence or anxiety behavior.

Late castration (after 1-2 heat cycles):

• Advantages: Hormonal and physical maturation is complete, resulting in a lower risk of incontinence and joint problems.
• Disadvantages: Slightly higher risk of mammary tumors than with early castration.

👉 Practical recommendation:
In my experience, the Castration after the first heat A good compromise: The body is mature, but the risk of hormone-related diseases remains low.

Conclusion from a veterinary perspective:
The decision regarding the Type of castration for female dogs The decision should always be made on an individual basis – taking into account age, health, breed, and living situation. In my practice, I discuss the various options in detail with each owner, because only a well-informed decision leads to a healthy and balanced dog in the long run.

Medical reasons for castration in dogs

From a veterinary point of view, there are several medical indications, in which castration is advisable or even necessary:

1. Tumor diseases

• Female dogs: With repeated heat cycles, the risk increases for Breast tumors (Mammary tumors). Early castration can significantly reduce the risk.
• Males: A neutered male dog cannot testicular tumor develop. In addition, the risk decreases for Prostate diseases.

2. Uterine diseases

Unspayed female dogs can suffer from a Pyometra (uterine infection) They develop a life-threatening inflammation that is often only recognized late. Castration completely prevents this disease.

3. Hormone-related behavioral problems

Some dogs exhibit pronounced sexual behavior or hormonally influenced aggression. Neutering can help in these cases – but only if the behavior is indeed hormonally based. A thorough behavioral analysis beforehand is essential!

---

When is the best time to neuter a dog?

The right time It depends on the individual dog.

For male dogs:

• At the earliest from the 6th to 12th month of life (depending on race and physical development).
• Large breeds should often be neutered later, as hormones affect bone growth.

In female dogs:

• Early castration before the first heat It almost completely reduces the risk of mammary tumors.
• Many veterinarians recommend, however, after the first or second heat cycle to castrate in order to promote hormonal and physical maturation.

A detailed consultation is crucial here.

Advantages of castration in dogs

1. No unwanted reproduction – especially important when keeping multiple dogs.
2. Reduction of hormonal disorders (e.g., endometritis, prostatic hyperplasia).
3. Fewer hormone-related behavioral problems, e.g. excessive marking, roaming or aggression towards rivals.
4. Calmer nature in some dogs (varies individually).
5. No stress during heat For female dogs and their owners.

---

Disadvantages and possible side effects

Like any surgical procedure, castration also has risks. Risks and disadvantages.

• Anesthesia risk: As with any surgery, especially in older or sick animals.
• Altered metabolism: Neutered dogs often have a lower energy requirement – obesity is a risk.
• Changes in coat texture: Especially possible in long-haired female dogs (softer, woollier fur).
• Changes in behavior: Not every dog becomes "better behaved" – in some breeds, insecurity or aggression can even increase.
• Hormone deficiency symptoms: For example, incontinence in female dogs (mostly treatable).

---

Alternative: Chemical castration

If you are unsure, you can first try... chemical castration try.

This involves inserting a hormone implant under the skin that suppresses testosterone production (in male dogs) or the cycle (in female dogs) for 6–12 months.

This method is well suited for „"Test"“, how the dog would behave after permanent castration.

---

The castration procedure at the veterinary practice

1. Preliminary examination: The dog will be thoroughly examined; blood values will be checked to minimize the risks of anesthesia.
2. Anesthesia: The procedure is performed under general anesthesia.
3. Operation:
   • In male dogs: removal of both testicles through a small incision in front of the scrotum.
   • In female dogs: removal of the ovaries (ovariectomy) or additionally of the uterus (ovariohysterectomy).
4. Recovery phase & aftercare: Pain medication, neck brace, check of the suture after 10–14 days.

Most dogs are fit again after a few days.

Cost of neutering a dog

The Costs They depend on size, gender and veterinary practice (according to GOT – fee schedule for veterinarians).

Dog type	Average costs (2025)
Male (small)	approx. €200–350
Male (large)	approx. €350–500

Behavior after castration: Practical tips

• Keep Calm: The dog needs 10–14 days of rest. No rough play or jumping.
• Wound check: Daily checks for swelling, redness, and oozing.
• Adjust your diet: Fewer calories to avoid weight gain.
• Observe behavior: Some dogs need time to regain hormonal balance.

Long-term effects on behavior and health

Long-term studies show:

• Castration can have certain effects reduce cancer rates, but others slightly increase (e.g. joint diseases in large breeds neutered early).
• Behavioral changes They are individual – some dogs become calmer, others more insecure.

Therefore: The decision should be made on an individual basis and after consultation with the veterinarian. be met.
