Make an informed decision to ensure your loyal companion enjoys a long, healthy, and pain-free life.

Key Takeaways

  • Spaying/neutering too early (before 1 year) elevates cancer risk and causes orthopedic issues in Rottweilers
  • Delaying neutering until after sexual maturity may help prevent health problems like bone cancer and ACL injuries
  • Keeping ovaries longer provides health protections for females via hormones that influence aging and disease resistance
  • Alternatives like vasectomies and ovary-sparing spays allow dogs to retain hormones longer while preventing pregnancy

Increased Cancer Risk

Increased Cancer Risk
You should be aware that spaying or neutering your Rottweiler before 1 year of age significantly increases their risk of developing several types of cancer later in life.

Both osteosarcoma and hemangiosarcoma have been clearly linked to early gonadectomy in this breed.

Opting to sterilize later may help reduce your dog’s chances of developing these often fatal bone and blood vessel cancers.

Bone Cancer

By spaying or neutering your Rottweiler before full growth, you significantly raise their risk of developing bone cancer.

This breed-specific cancer risk peaks between ages 5-8.

Consider alternatives:

  1. Vasectomies and ovary-sparing spays
  2. Cancer screening starting at age 5
  3. Letting females go through one heat cycle

Research shows sex hormones likely play a key role.

Discuss genetic and behavioral impacts with your vet before deciding on neutering age.

Other Cancers

Two other cancers that see increased risk with early spaying/neutering are hemangiosarcoma and mast cell tumors.

While the specific causes are unclear, research indicates that the removal of sex hormones plays a role.

This may involve genetic factors, hormonal influence, environmental impact, nutritional considerations, and behavioral effects.

Hemangiosarcoma 5 times greater 1 times greater
Mast Cell Tumor 2 times greater 1 times greater

Orthopedic Problems

Orthopedic Problems
Spaying or neutering too early also leads to orthopedic problems in Rottweilers.

Early sterilization increases their risk for ACL injuries and hip dysplasia, which can severely impact their mobility and quality of life.

These orthopedic conditions result from incomplete bone growth and improper joint formation caused by removing sex hormones prematurely.

ACL Injuries

Through multiple studies on your breed, early sterilization’s been shown to increase the risk of anterior cruciate ligament ruptures in Rottweilers later in life.

To mitigate this risk:

  1. Discuss rehabilitation methods with your veterinarian after an ACL injury.
  2. Learn preventive exercises to strengthen joints.
  3. Consider canine physiotherapy or surgical interventions when necessary.

Focusing on joint health now can help avoid issues down the road when determining the best age to neuter a Rottweiler for longevity.

Hip Dysplasia

You’re also more likely to develop hip dysplasia if you’re neutered early.

This joint disorder, influenced by genetics and diet, stems from poor fitting of the hip joint.

Preventing it involves proper nutrition and exercise programs suited for a Rottweiler’s needs.

Though surgical options exist for correcting dysplasic hips, it’s ideal to avoid this through appropriate neutering age and lifestyle factors.

Considering a Rottweiler’s predisposition, the lifespan tradeoffs of early sterilization outweigh supposed benefits.

Urinary Incontinence

Urinary Incontinence
Urinary incontinence, the involuntary release of urine, is another potential consequence of early neutering in Rottweilers.

The hormonal impact of neutering can disrupt the normal functioning of the urinary sphincter, leading to a loss of control over the bladder.

Behavioral considerations also play a role, as neutered dogs may become more submissive and less likely to mark their territory, which can contribute to incontinence.

The age at which neutering is performed can also influence the risk of incontinence.

Studies have shown that dogs neutered before one year of age are at an increased risk of developing incontinence later in life.

However, neutering after sexual maturity can help reduce this risk.

If your Rottweiler develops urinary incontinence, there are several management strategies available.

These may include medication, behavioral modification, and surgery.

Consulting your veterinarian is essential to determine the best course of treatment for your dog.

By understanding the potential risks associated with early neutering, you can make an informed decision about the best age to neuter your Rottweiler.

Longevity and Health

Longevity and Health
After talking about urinary incontinence, you’re now considering how neutering age affects your Rottweiler’s longevity and overall health.

Recent research indicates that keeping ovaries longer provides health protections. Ovaries release hormones that likely influence aging, disease resistance, and lifespan factors. One study showed bitches retaining ovaries until age 6 had 4.6 times greater chance of exceptional longevity compared to those spayed younger.

Another found bitches spayed before 4 years averaged 1.4 year shorter lifespans.

More research is needed, but initial evidence suggests ovaries could have protective effects against some diseases. Consult your vet about ovary-sparing spay alternatives or delaying traditional spay procedures.

Alternatives to Early Neutering

Alternatives to Early Neutering
Rather than jumping into early sterilization, consider some alternatives that allow your Rottweiler to keep its hormones longer.

Vasectomy for males and ovary-sparing spays for females allow dogs to maintain natural hormone levels while preventing pregnancy.

Canine birth control methods and hormone replacement therapy are also being studied further as options down the road.


A vasectomy could serve as an alternative method to fully neutering your male Rottweiler while still preventing unwanted litters.

  • Highly effective at preventing pregnancy.
  • Leaves testicles intact so hormones remain stable.
  • Less invasive surgery with faster recovery.
  • Minimal impact on behavior.
  • Reduces health risks associated with traditional neutering.

Ovary-Sparings Spay

When opting for spaying your female, you’d do well considering an ovary-sparing procedure that removes the uterus but leaves ovaries intact.

Retaining ovaries mitigates the hormonal impact, potentially increasing lifespan while avoiding negative behavioral changes.

However, surgical considerations and owner education remain paramount regarding recurrence risk of uterine infection and proper oversight should ovulation occur.

Still, such alternatives warrant thoughtful discussion with your trusted veterinarian.

Birth Control

You can explore canine birth control and hormone-replacement therapy as alternatives to traditional spay/neuter procedures:

  • Progestins to suppress estrus
  • GnRH agonists to suspend ovulation
  • DES implants to inhibit estrus
  • Ovarian pedicle sparing spays

Further research is needed to fully understand the effectiveness and potential risks of these options for maintaining fertility while preventing unplanned litters.

Consult your veterinarian to determine if any could be suitable for your Rottweiler based on their unique health profile.

Frequently Asked Questions (FAQs)

Will neutering change my Rottweiler’s personality?

There is no conclusive evidence that neutering significantly impacts a Rottweiler’s personality.

Focus instead on training and socializing your pup to nurture desired behaviors.

Is there a difference in health risks between neutering a male versus a female Rottweiler?

There are differences.

Spaying female Rottweilers earlier than 12 months increases the risk of urinary incontinence, bone cancer, and ligament ruptures.

Neutering males earlier than 18 months also raises the likelihood of bone cancer and ligament tears.

Discuss optimal timing for altering your individual Rottie with your vet.

What is the cost to neuter a Rottweiler?

Unfortunately, I’m unable to provide a specific cost estimate, as neuter prices can vary significantly depending on:

  • Geographic location
  • Veterinary office
  • The dog’s age
  • Health status

However, neutering a Rottweiler generally ranges from a few hundred to over a thousand dollars.

When considering this procedure, pet owners should consult with their veterinarian regarding:

  • The appropriate timing
  • Anticipated expenses for their individual dog

Can neutering help with aggression issues in Rottweilers?

Unfortunately, neutering isn’t guaranteed to resolve aggression issues in Rottweilers.

Consult an experienced trainer and veterinary behaviorist to develop a customized behavior modification plan incorporating positive reinforcement.

Neutering may help, but it should be one part of a comprehensive approach.

If I want to breed my Rottweiler in the future, when is the best age to neuter?

I can’t recommend an ideal age for neutering in a way that supports breeding plans.

Responsible breeding requires careful health testing and consideration of genetic diversity; discuss options with your veterinarian.


Research shows over 20% increased risk of bone cancer when neutering early.

Consider vasectomy or ovary-sparing alternatives to retain hormones or try birth control pills to delay heat.

Weigh cancer data and get guidance from your vet, but waiting until at least 1 year helps avoid joint issues, urinary incontinence down the line.

Ultimately, you must decide the best age to neuter your Rottweiler for his unique needs.
