The Spay/Neuter Dilemma: Unveiling the Impact on Longevity and Health in Dogs

Updated: Jul 16, 2023


When it comes to spaying and neutering our beloved dogs, there has been an ongoing debate surrounding the optimal timing for these procedures. Over the years, research and understanding have evolved, shedding light on the potential effects of early spay/neuter on the longevity and overall health of our canine companions. In this article, we will delve into the subject, exploring the findings of a groundbreaking study conducted on Rottweilers and discussing the importance of responsible decision-making when it comes to spay/neuter timing. Let's embark on a journey to uncover the facts and considerations surrounding this controversial topic.

  1. The Study that Started the Conversation: Around two decades ago, Dr. David Waters from the Gerald R Murray Cancer Center approached the Rottweiler community to study longevity using this breed as a model. The research team made an intriguing discovery that hormones play a significant role in female longevity. Their findings suggested that the age at which females are spayed can impact their chances of reaching an older age. The study revealed that females spayed under the age of 2 had a particular chance of reaching 13 years of age, while those spayed between 2 and 6 years had twice the chance, and those spayed over 6 years had three times the chance. This unexpected outcome highlighted the potential influence of spay/neuter timing on longevity, emphasizing the need for further investigation.

  2. The Impact of Timing: One of the crucial insights gained from Dr. Waters' research is the significance of noting the timing of spay/neuter in previous studies. The absence of this information may have skewed earlier research and led to incomplete understandings. As a result, it is essential to consider the timing factor when evaluating the potential effects of spay/neuter on a dog's health and longevity.

  3. Breed Variations and Individual Considerations: It's important to recognize that breeds vary in terms of longevity and prevalent diseases. Consulting with your breeder can provide valuable insights into breed-specific considerations. They can help guide you in the decision-making process regarding spay/neuter timing, taking into account the breed's characteristics, potential health risks, and individual circumstances.

  4. Responsible Decision-Making: Early spay/neuter has often been seen as a medical response to prevent irresponsible breeding and reduce the number of unwanted puppies. However, it is crucial to evaluate the potential trade-offs between the benefits of spaying/neutering and the impact on the dog's health. Dr. Waters' research and the evolving understanding of the topic highlight the importance of responsible decision-making, considering the individual dog's well-being.

  5. Veterinarian Perspectives: Many veterinarians advocate for early spay/neuter due to concerns about their clients' ability to prevent unwanted pregnancies and the resulting burden on shelters and rescue organizations. However, it is crucial to engage in conversations with your veterinarian, share your concerns, and discuss the potential benefits and risks associated with different spay/neuter timing options. Collaborating with your veterinarian can help you make an informed decision that takes into account the unique needs of your dog.

  6. Personal Choice and Contractual Agreements: As responsible pet owners, we have the power to shape the conversation and make choices that prioritize our dogs' well-being. Some individuals and breeders - and we do advocate for this at Northwest Lagotto - have chosen to opt for spay/neuter procedures after the age of 2 years, allowing for additional health screenings, such as permanent OFA Hip x-rays, to be performed simultaneously. These choices are often reflected in contractual agreements, enabling a more comprehensive approach to the health and longevity of our beloved companions.

The debate surrounding the optimal timing for spay/neuter procedures in dogs is multifaceted and requires careful consideration. Dr. David Waters' research on Rottweilers has shed light on the potential impact of spay/neuter timing on longevity. However, it is essential to recognize that individual considerations, breed variations, and responsible decision-making should guide our choices. Engaging in open conversations with breeders and veterinarians, seeking the latest research findings, and evaluating the potential benefits and risks can help us make informed decisions that prioritize the health and well-being of our furry friends. Ultimately, our commitment to responsible ownership and the well-being of our pets should drive our choices regarding spay/neuter timing. So, let's continue to educate ourselves, engage in meaningful discussions, and make decisions that serve the best interests of our canine companions.
