9 Dog Breeds That Should Be Neutered Later

Neutering is a responsible and common practice for dog owners, but timing can make a big difference—especially for certain breeds. While early neutering helps control pet overpopulation and can prevent unwanted behaviors, it may not be the best option for all dogs.

Some breeds, particularly large and giant breeds, need more time to physically and hormonally mature before undergoing the procedure. Early neutering in these dogs has been linked to higher risks of joint problems, certain cancers, and behavioral issues. In this guide, we’ll explore 9 dog breeds that should be neutered later to support their long-term health and well-being.

Whether you’re a first-time dog owner or a seasoned pet parent, understanding the ideal neutering timeline for your dog’s breed is essential. Waiting just a few extra months can significantly reduce health risks and improve your dog’s quality of life. Let’s dive into the breeds that benefit most from delayed neutering.

1. Golden Retriever

Golden Retrievers are a popular breed known for their friendly demeanor and intelligence. However, studies have shown that early neutering (before 12 months of age) may increase their risk of developing certain health issues, especially joint disorders like hip dysplasia and cranial cruciate ligament tears.

Additionally, early neutering in this breed has been linked to a higher risk of certain cancers such as hemangiosarcoma and lymphoma. Since Golden Retrievers are a larger breed that continues growing well into their second year, their hormonal development plays a significant role in proper bone and muscle growth. Waiting until they are fully matured—ideally between 18 to 24 months—allows their joints and bones to strengthen properly.

This timing also ensures that their immune system and endocrine functions are more stable, reducing the risk of disease. For male Golden Retrievers especially, delaying neutering can help maintain natural testosterone levels that are vital during their growth phase.

2. Labrador Retriever

Labrador Retrievers are another large breed that should be neutered later, ideally after 18 months. Similar to Golden Retrievers, they are prone to joint disorders and certain types of cancer if neutered too early. Research from the University of California, Davis, found that neutering Labradors before 12 months of age can double the risk of hip dysplasia and triple the risk of cranial cruciate ligament injuries.

These issues arise because early neutering disrupts the hormonal balance necessary for the proper closure of growth plates in the bones. Labradors are also highly energetic and need strong muscular development to avoid injury, which is better supported by delaying neutering.

Additionally, behavioral issues such as anxiety and fear-based aggression may be more pronounced in Labs neutered too early. By allowing them to mature both physically and emotionally, dog owners can support healthier development and avoid costly medical problems down the line.

3. German Shepherd

German Shepherds are widely used in law enforcement and as service animals because of their intelligence and strength. However, they are also among the breeds most vulnerable to musculoskeletal issues. Early neutering, especially before 1 year of age, has been shown to significantly increase the risk of joint problems like hip dysplasia and degenerative myelopathy. This is largely due to the delay or disruption in the closure of their growth plates, which are sensitive to hormonal changes. German Shepherds continue to grow well into their second year, so neutering too early can result in uneven bone growth, making them more prone to injury. Moreover, some studies indicate that early neutering may also increase the likelihood of certain cancers, such as hemangiosarcoma and osteosarcoma. Waiting until they are at least 18 to 24 months old not only ensures proper skeletal development but also supports mental maturity and better behavioral outcomes.

4. Rottweiler

Rottweilers are powerful, large dogs with a naturally protective temperament. Early neutering in Rottweilers has been linked to an increased risk of several health problems, including bone cancer (osteosarcoma), which is more common in large breeds.

Studies have shown that neutering before 12 months can quadruple the risk of developing this deadly disease. Additionally, Rottweilers are at a higher risk of joint disorders such as hip dysplasia and ACL injuries when neutered too young. Their skeletal system requires more time to mature, and the hormonal support during adolescence is crucial for proper bone density and muscle development.

Rottweilers also benefit behaviorally from delayed neutering, as early removal of hormones can increase anxiety and lead to undesirable aggression or fearfulness. Most veterinarians recommend waiting until at least 24 months before neutering a Rottweiler, especially in males, to minimize these risks and promote a healthier and more balanced development.

5. Bernese Mountain Dog

The Bernese Mountain Dog is a giant breed with a gentle, affectionate personality. However, this breed is particularly prone to cancer, with nearly half of all Bernese Mountain Dogs developing some form of the disease in their lifetime.

Early neutering has been associated with an increased incidence of cancers such as mast cell tumors, lymphoma, and hemangiosarcoma. Moreover, being a giant breed, their bones take longer to mature, and early neutering can delay growth plate closure, leading to skeletal abnormalities. Joint issues such as hip and elbow dysplasia are also common if they are neutered before they are fully developed.

Because their lifespan is already shorter than average (about 6–8 years), preserving their overall health is essential. Waiting until they are 18 to 24 months old helps ensure they grow properly and minimizes their already high cancer risk. Delaying neutering in Bernese Mountain Dogs is a proactive step toward improving both their quality and length of life.

6. Great Dane

Great Danes are among the tallest dog breeds, and their growth process is prolonged, often continuing until they are 24 months old or even longer. Early neutering in Great Danes can significantly interfere with proper bone development, leading to orthopedic problems such as panosteitis, joint laxity, and hip dysplasia.

The hormonal signals that regulate growth are vital in this breed and help their bones and joints align correctly. Additionally, early neutering may contribute to heart problems, especially dilated cardiomyopathy, which this breed is genetically predisposed to. Since Great Danes already have a shorter lifespan (6–8 years), preserving their overall structural integrity is crucial.

Neutering too early may also affect their temperament, leading to increased shyness or fear-based behaviors. Veterinarians usually recommend waiting until at least 18 to 24 months of age before considering neutering. This timing supports not only physical maturity but also ensures they are emotionally ready for such a significant hormonal change.

7. Boxer

Boxers are a high-energy, medium-to-large breed with a strong predisposition to cancer, particularly mast cell tumors and lymphoma. Neutering Boxers too early—especially before 1 year of age—may significantly increase the risk of these cancers. While they are not as large as some of the other breeds on this list, their growth and hormonal development still benefit from delayed neutering.

Studies suggest that Boxers neutered later in life have lower incidences of certain health conditions, including hypothyroidism and joint issues. Additionally, Boxers are known for their playful yet stubborn personality, and early neutering may interfere with proper behavioral development.

Delaying the procedure until they are around 18 months old allows time for physical maturity and emotional stabilization, both of which are crucial for managing their high energy and training needs. Responsible timing can help improve both their longevity and their quality of life.

8. Doberman Pinscher

Doberman Pinschers are known for their loyalty, intelligence, and sleek build. They are a breed that can suffer from a range of inherited conditions, including cardiomyopathy and cancer. Neutering too early may increase their risk of developing health problems such as osteosarcoma and certain hormonal imbalances.

Since Dobermans are medium-to-large dogs that continue maturing into their second year, early neutering can also lead to uneven skeletal growth and higher susceptibility to orthopedic injuries. From a behavioral standpoint, early neutering can contribute to anxiety or increased reactivity, especially in males.

Delaying the procedure until 18 to 24 months helps ensure that they have completed most of their growth and developed the muscle tone and bone density needed for their size. This also allows for better socialization and training outcomes, as they are more emotionally stable. Overall, waiting to neuter a Doberman can reduce long-term health risks and improve their well-being.

9. Australian Shepherd

Australian Shepherds are intelligent, agile herding dogs that require both physical and mental stimulation. Though they are not a giant breed, early neutering has been linked to an increased risk of joint problems such as hip dysplasia and cranial cruciate ligament tears in Aussies.

These issues arise when growth plates close abnormally due to lack of hormones, causing the legs to grow unevenly. Additionally, Australian Shepherds are prone to autoimmune diseases and certain cancers, which may be aggravated by early neutering. Behavioral issues like noise phobia, anxiety, and hyperactivity can also become more prominent in early-neutered dogs of this breed.

Experts generally recommend delaying neutering until at least 18 months of age for both males and females to reduce these risks. This waiting period allows their bodies to mature properly and helps in achieving a more balanced temperament, which is essential for training and herding activities. Delayed neutering supports a longer, healthier life for Australian Shepherds.

Bottom Line

While neutering is beneficial for most dogs, the timing can vary greatly depending on the breed. Larger breeds like Golden Retrievers, German Shepherds, and Rottweilers often benefit from being neutered later—typically after 18 to 24 months—due to their slower growth and increased risk of health issues when altered too early.

By allowing your dog to fully mature before neutering, you can help ensure healthier bones, reduced cancer risk, and improved behavioral development. Always consult with your veterinarian to make the best decision for your specific dog’s needs. A well-timed approach to neutering supports both longevity and a better quality of life.
