11 Signs Your Dog Needs to Be Neutered

One crucial decision that often arises in the lifetime of a dog owner is whether to spay or neuter their canine companion. Neutering, specifically, refers to the surgical removal of a male dog's testicles. Besides the obvious prevention of unwanted litter, there are many reasons for neutering. In this article, we will explore the signs that indicate your dog needs to be neutered, and the reasons why it may be the best choice for your furry friend's long-term health and happiness.

What Is Neutering?

Neutering is a surgical procedure performed on animals, typically on male dogs and cats, to render them sterile or unable to reproduce. The same procedure performed on females is called "spaying." Neutering involves the removal of the testicles in male animals, which eliminates their ability to produce sperm and results in the animal being unable to father offspring. The primary purposes of neutering include population control, preventing unwanted litters of puppies or kittens, and helping to reduce the number of stray or abandoned animals.

Is Neutering Painful?

The procedure is generally done under general anesthesia, which means the dog is unconscious and does not feel pain during the surgery itself. Once the surgery is complete, the dog will be in recovery, and some discomfort or pain may be expected as the anesthesia wears off and the healing process begins.

When Should You Neuter Your Dog?

In some cases, puppies are neutered as early as 6 to 9 weeks of age, especially in certain rescue or shelter situations. But most commonly, dogs are neutered between 6 to 12 months of age. This age range allows the dog to reach sexual maturity while avoiding unwanted litters and behavioral issues associated with intact males. For larger breeds, some veterinarians recommend waiting until the dog is fully physically mature, which is around 1 year of age or older, before performing the neutering procedure. This approach aims to allow for proper growth and development of the dog's bones and joints.

11 Signs Your Dog Needs to Be Neutered

Determining when to neuter a dog can depend on various factors, including the breed, size, and individual health conditions. Neutering is usually recommended at a certain age, but it's essential to consult with a veterinarian to determine the best timing for your specific dog. That said, here are some signs that may indicate it's time to consider neutering your dog:

1. Sexual Behavior

If your dog exhibits intense sexual behaviors, such as excessive humping or trying to escape to find a mate, neutering may help to alleviate these behaviors.

2. Marking

Male dogs may mark their territory by urinating on objects like furniture or walls. Because male dogs have a specialized gland called the "scent gland" or "preputial gland" located near their genitals. This gland produces a unique chemical mixture that gives each dog a distinct scent. When a male dog urinates, he releases a small amount of urine infused with these pheromones, which serve as a personal calling card. However, excessive marking may indicate a problem and maybe a sign that your dog needs to be neutered and is a hassle to deal with, neutering might help decrease this behavior.

3. Roaming Tendencies

Male dogs, like many other animals, may exhibit roaming tendencies if they are not neutered. Roaming behavior in male dogs refers to their inclination to wander away from home or their designated area, often in search of a mate or due to heightened territorial instincts. If an intact male dog detects a female in heat nearby, he may become overly focused on finding her, leading him to roam long distances. They may become more vocal, howling or barking more frequently to attract females or communicate with other dogs.

4. Aggression and Dominance

Testosterone, the primary male hormone, can contribute to aggressive behaviors in some male dogs. Neutering can help decrease the levels of testosterone, making your pet more amicable and less prone to aggression towards other animals and humans. However, it's essential to note that neutering might not entirely eliminate aggressive tendencies, especially if the behavior has been ingrained for a long time. Additional behavioral training may be necessary in such cases.

5. Vocalization

Unneutered males may become more vocal, howling or barking more frequently to attract females or communicate with other dogs.

6. Health Benefits

Neutering can provide several health benefits for your male dog. It reduces the risk of certain reproductive-related health issues, such as testicular cancer and prostate problems. Additionally, it can lower the likelihood of your dog developing certain behavioral problems that may arise from mating instincts.

Some of these diseases are:

Dog Testicular Cancer

Testicular cancer in dogs is a type of cancer that affects the testicles, which are the male reproductive organs responsible for producing sperm and testosterone. It is more common in intact (unneutered) male dogs but can occur in neutered dogs as well. Symptoms of testicular cancer may include swelling or lumps in the testicles, pain or discomfort in the scrotum, or changes in the size and texture of the testicles. Neutering can prevent testicular cancer, as the removal of the testicles eliminates the possibility of this type of cancer.

Dog Prostatic Disease

Prostatic diseases in dogs involve the prostate gland, a small organ located near the bladder and surrounding the urethra. Prostatic issues can occur in intact male dogs due to hormonal influences. Common prostatic problems include benign prostatic hyperplasia (BPH), prostatitis (inflammation of the prostate), and even prostate cancer. Neutering can reduce the risk of prostatic diseases, as the removal of the testicles decreases hormonal influences on the prostate.

Dog Cryptorchidism

Cryptorchidism is a condition in which one or both of a male dog's testicles fail to descend into the scrotum as they should during development. Instead, the undescended testicle(s) may remain in the abdomen or inguinal canal. This condition is more commonly seen in certain dog breeds and can lead to an increased risk of testicular cancer. Neutering is usually recommended for dogs with cryptorchidism to prevent the development of testicular cancer and to avoid the potential complications associated with retained testicles.

Dog Scrotum Rashes

Scrotum rashes in dogs can be caused by various factors, including allergies, infections, insect bites, or dermatitis. The scrotal area is sensitive, and any irritation can lead to redness, itching, swelling, or discomfort for the dog. Maintaining good hygiene and cleanliness in the scrotal area is essential. Neutering can also help prevent certain skin conditions, as it eliminates the hormonal fluctuations that might contribute to skin issues in intact male dogs.

If you notice any concerning symptoms in your dog, such as lumps, swelling, rashes, or behavioral changes, it's essential to have them examined by a veterinarian. They can properly diagnose the issue and recommend the appropriate course of action, which may include neutering if it hasn't been done already. 

7. Overpopulation and Responsible Pet Ownership

One of the most significant reasons to consider neutering your dog is to prevent overpopulation. Countless dogs end up in shelters or living as strays due to irresponsible breeding practices. By neutering your dog, you contribute to controlling the pet population and decrease the number of unwanted animals in need of homes.

8. Mounting

Intact male dogs may frequently mount other dogs, objects, or even people as a way of expressing dominance or mating behavior. Neutering can help reduce this behavior, although it may not eliminate it entirely.

9. Vigorous Scent Detection

As a male dog nears a female, he engages in intense sniffing around her rump or genital area, aiming to detect pheromones that reveal her reproductive status. Whether on walks, in the park, or any other place, the male dog will persistently trail the female's scent. Even timid and introverted dogs will overcome their shyness to pursue the alluring scent of the female.

10. Genetic Defect

When it comes to the health of male dogs, there are important considerations to keep in mind, particularly concerning genetic defects that can be inherited by their offspring. Some of these issues can be quite severe, underscoring the importance of neutering male dogs, especially if they possess a genetic defect. Neutering your dog before it reaches sexual maturity or after identifying a genetic problem in adulthood becomes crucial to prevent the transmission of inherited issues to future generations of dogs.

By opting to have your male dog neutered, you can effectively halt the propagation of these genetic problems. There are various common examples of genetic defects in dogs, including different forms of cancer, hip and elbow dysplasia, patella luxation, intervertebral disk disease, epilepsy, hypothyroidism, congenital heart anomalies, atopic disease, early-onset cataracts, and progressive retinal atrophy.

11. Countries and States Requiring Neutering

If you are in Los Angeles, it is highly likely that you will need to have your male dog neutered. In 2008, Los Angeles County implemented one of the strictest spay and neuter laws nationwide. It states that most dogs and cats must be fixed by the age of four months. However, there are some exceptions. Dogs and cats involved in performances or sports competitions, those belonging to professional breeders, guide dogs, or animals used by the police are exempt from this requirement.

In nearly 32 states, animal shelters and similar facilities are required to spay or neuter dogs before they are adopted. If someone wishes to adopt an intact male dog, they often must sign an agreement committing to having the licensed veterinarian neuter the dog within 30 days after adoption. Here are some states where neutering is required:

• Alabama
• Arizona
• California
• Arkansas
• Connecticut
• Colorado
• District of Columbia (Washington D.C.)
• Delaware
• Lowa
• Florida
• New York
• Georgia

Please note that this list may not be exhaustive, and other states or countries may also have regulations regarding spaying and neutering of dogs. It's important to stay informed about local laws and ordinances to ensure responsible pet ownership.

How Long Do Dogs Need to Recover After Being Neutered?

Most dogs recover fully within a few days to a week after the procedure.

However, most dogs experience only mild to moderate discomfort after the procedure. Veterinarians often prescribe pain medications or provide other pain management techniques to help alleviate any post-operative discomfort.

Common signs of discomfort or mild pain after neutering may include:

• Mild lethargy or decreased activity
• Reluctance to move or jump
• Slightly decreased appetite
• Some swelling or redness around the incision site

These signs are generally temporary and should improve as the healing process progresses.

Do Dogs Need to Wear a Cone After Being Neutered?

In many cases, dogs are required to wear a cone or an Elizabethan collar (e-collar) after being neutered. The cone is used to prevent the dog from licking, biting, or scratching the surgical incision site, which is essential for the proper healing process. Licking or chewing the surgical incision can introduce bacteria from the dog's mouth to the wound, increasing the risk of infection.

Signs of Infection After Neutering Dog

Signs of infection after neutering a dog may vary depending on the severity of the infection and the individual dog's response. It's essential to monitor your dog closely after the surgery and be vigilant for any signs of infection. If you suspect that your dog's incision site is infected, contact your veterinarian immediately for proper evaluation and treatment. Here are some common signs of infection after neutering a dog:

• Swelling: A certain degree of swelling around the incision site is normal in the immediate post-operative period. However, if the swelling persists, increases in size, or becomes hot to the touch, it could indicate an infection.
• Redness and inflammation: The skin around the incision may appear redder than usual or inflamed. This can be a sign of infection.
• Pus or discharge: If you notice any pus or thick yellow, green, or brown discharge coming from the incision, it is a clear sign of infection.
• Excessive warmth: The area around the incision may feel warmer than the rest of the body due to increased blood flow to the infected area.
• Foul odor: An unpleasant or foul odor coming from the incision site is often a sign of infection.
• Lethargy: Infected dogs may appear more tired, lethargic, and less interested in usual activities.
• Loss of appetite: A dog with an infection may have a reduced appetite or may stop eating altogether.
• Fever: In some cases, an infection can cause a fever. If you notice any signs of a high temperature in your dog, such as a warm nose, shivering, or lethargy, it could be an indication of infection.

What Are the Risks of Dog Neutering?

Anesthesia risks

Neutering requires the use of anesthesia, which can present risks, especially for dogs with underlying health issues or sensitivities to anesthesia. 

Increased likelihood of some cancers

Dr. Benjamin Hart and his research team at the University of California, Davis, have conducted a study comparing the long-term health differences between neutered and intact dogs of the same breed. The study analyzed 35 different breeds, and the results showed variations in health outcomes.

For certain breeds, such as the Golden Retriever, the study found that neutered dogs were 3 to 4 times more likely to develop conditions like hip dysplasia and certain types of cancers compared to their intact counterparts. On the other hand, for most breeds weighing under 20 pounds, with the exception of the Shih Tzu, there were virtually no significant differences in health outcomes between neutered and intact dogs.

This research sheds light on the fact that the impact of neutering on a dog's health can differ significantly based on breed, and it emphasizes the importance of individualized considerations when making decisions about neutering. Dog owners should consult with their veterinarians to understand the potential risks and benefits of neutering based on their specific dog's breed, age, and health status.

Hormonal changes

Neutering involves the removal of the testicles, which results in a decrease in certain hormones like testosterone. This hormonal change can potentially impact the dog's metabolism, behavior, and overall health. However, these changes are usually manageable and often lead to positive behavioral improvements.

How Long After Neutering Dog Is Testosterone Gone?

Within 24 to 48 hours after the surgery, the dog's testicles are removed, and the production of testosterone, which primarily occurs in the testes, ceases.

However, it's important to note that the effects of testosterone in the dog's body can still be present for a short period after the surgery. The hormone may take a few days to fully dissipate from the dog's system. During this time, some residual testosterone may still be circulating in the bloodstream.

FAQs

Will Neutering Stop a Dog From Peeing in the House?

While neutering has many benefits, such as preventing unwanted litters and reducing the risk of certain health issues, it may not directly address the issue of a dog peeing in the house.

Dogs may urinate indoors for various reasons, and it's essential to identify the underlying cause to effectively address the behavior. 

Do Dogs Gain Weight After Being Neutered?

Yes, dogs can gain weight after being neutered. Neutering, which is the surgical removal of a male dog's testicles, can lead to some changes in a dog's metabolism and behavior, potentially contributing to weight gain. 

Conclusion

Deciding whether to neuter your male dog is an important responsibility that requires careful consideration. Paying attention to the signs indicating that your dog needs to be neutered, such as age and maturity, roaming tendencies, aggressive behavior, and marking, can help you make an informed decision. Neutering not only helps manage unwanted behaviors but also provides essential health benefits while promoting responsible pet ownership.
