Neutering Of Male Dogs: What You Should Know About This Practice
An integral component of being a responsible pet owner is spaying or neutering your animal companion, a word that can refer to either male or female animals.
It is difficult to develop a convincing argument against the procedure because there are a lot of very good reasons, some of which will be given below.
The only animals that are meant for breeding later in life are among the few exceptions to this rule. Castration, sometimes known as neutering, is a procedure that is performed on male dogs.
This procedure helps with population management, minimizes roaming and aggressive behaviors in dogs, and lowers the risk of several common hormone-related diseases.
Castration by complete surgical excision, including removal of the testicles, is the standard procedure; however, there are other options, which will also be covered in this article.
An Overview Of The Male Reproductive System And Its Anatomy
The production and distribution of sperm as a means of transmitting an individual’s genetic information to future generations is the major purpose of the male reproductive system.
The testicles and the penis make up the external genitalia, and they are both found in the scrotum, which is placed between the two sets of hind limbs.
Internally, sperm travel from the testicles through the paired ductus deferens and then exit through a tube-like structure known as the urethra.
The sperm and other fluids, including a significant volume of fluid coming from the prostate, are then expelled through the urethra. This is also the route through which other fluids are expelled.
The prostate is a gland that produces secretions and is located at the neck of the bladder. It has a drainage system that empties into the urethra near the place where the ductus deferens enter the body.
The fact that the prostate, in addition to enclosing the neck of the bladder, also sits in close touch with the rectum in the pelvic canal is a fact that will become crucial later on in our discussion.
The prostate also sits in close contact with the rectum in the pelvic canal.
The testicles are responsible for the majority of the body’s testosterone production in addition to their role in the creation of sperm.
Androgens are a specific type of hormone that are responsible for the development of typical male physical and behavioral patterns.
These patterns include the promotion of the growth of lean muscle mass, sexual behavior, and possibly aggressive and dominant-type behaviors.
Castration Is Performed For Medical Reasons.
Cryptorchidism
During the foetal stage of development, the testicles of a male dog form in close proximity to the kidneys. They then begin the gradual process of moving toward the scrotum, which is the final destination of the testicles.
A muscle component known as the gubernaculum is responsible for regulating and controlling this process. This trip does not always go as planned, and it is possible that one or both testicles will become “stuck” along the road.
The medical word for this ailment is cryptorchidism, and it is seen in a variety of dog breeds, including Maltese and Greyhounds, amongst others.
Although the entrapped testicle (or testicles) are almost always found in the inguinal canal, which is the channel between the abdomen and the outer abdominal wall, it is possible for them to be found anywhere along the course that has been described.
It is possible to diagnose the problem in male puppies that are 12 weeks old or older and do not have both testicles within the scrotal sac. However, in some toy breeds, complete descent of the testicles can (very rarely) take an additional six months.
The retained testicle will continue to be hormonally active and produce at least as much testosterone as a normal testicle, despite the fact that it will be significantly smaller than a testicle that is normally placed in the scrotum.
In addition to this, men with retained testicles have a much-increased likelihood of acquiring cancers in their later years (see below). Because of this, castration is regarded to be a must for affected canines.
Dogs with cryptorchidism who have at least one normal testicle are likely to be reproductive and will pass on the condition to a significant proportion of the male progeny they have.
Tumors
Unneutered male dogs, namely those of certain breeds, such as Boxers, German Shepherds, and Maltese, are more likely to develop testicular tumors than neutered male dogs. This greater incidence is recognized.
There are a number of distinct subtypes of testicular tumors, each of which has the potential to be either benign or malignant. Even if an attentive owner or veterinary surgeon could discover such growths at an early stage, the majority of them end up becoming rather large and can generate other symptoms.
These symptoms vary according to the type of cell that the tumor comes from. Testicular tumors, in general, are more common in older dogs, namely those who are above 10 years old. The following paragraphs will go through the top two most common types of testicular tumors.
Sertoli Cell Tumors
In a healthy body, the Sertoli cells are the ones in charge of fostering the development of the sperm cells. Oestrogen is one of the female sex hormones, and one of the mechanisms via which they accomplish this is by producing very little levels of the hormone in question.
Tumors that originate from Sertoli cells have the ability to release significantly more estrogen, which could lead to feminization syndrome in the dog. This condition causes the dog to experience hair loss, adopt a more feminine urination position, and become more appealing to other male canines.
There is also the possibility of other symptoms, such as anemia. The hormonal imbalance can also cause alterations to the cells that line the prostate, a process known as squamous metaplasia, which can lead to the loss of blood in the urine or ejaculate.
Malignant Sertoli cell tumors make up about one out of every seven cases and have the potential to metastasize, or spread, to other parts of the body. They are more prevalent in dogs who have cryptorchidism.
Leydig/Interstitial Cell Tumors
In contrast, Leydig cell tumors often have a diameter of less than one inch on average, whereas Sertoli cell tumors are almost always quite large when they are found.
These are normally non-cancerous conditions that may be discovered accidentally during a veterinary examination. However, they can also induce an increase in the number of female hormones that are circulating in the body.
As a result, they can cause some of the symptoms that are associated with Sertoli cell tumors, albeit in a manner that is often less severe. The most typical adverse effects include alterations to the prostate, which might ultimately result in prostatitis and infection.
Prostate Disorders
Inflammation
A hormonal profile that is well-balanced will result in a prostate that is normal in size and in good health. As was previously mentioned, alterations in the levels of these hormones, which can be seen in testicular tumors, can lead to internal changes that make the prostate susceptible to infection and can lead to the development of cystic, fluid-filled cavities.
This can occur when testicular tumors are present. Because the prostate is also a very sensitive organ, alterations of this nature typically cause a significant amount of pain and discomfort.
To the owner, this may simply appear as changes in behavior, and the owner of more than one older dog who was suffering from prostatitis characterized their dog as simply becoming a “grumpy old man.”
In most cases, the cause of the issue may be identified with a comprehensive veterinary exam that also includes palpation of the prostate; however, in rare cases, a study of the urine and an abdominal ultrasound examination may be required.
Benign Prostatic Hyperplasia
Even in the absence of shifts in hormone levels, the prostate has a tendency to expand and become problematic with increasing age. This is true even when there is no change in hormone levels.
Prolonged stimulation by testosterone can produce gradual expansion of the organ, with or without concomitant inflammatory or cystic alterations. This can happen with or without the presence of cysts.
This condition is referred to as benign prostatic hyperplasia (BPH), and its symptoms include either bleeding from the urethra or difficulty passing feces.
Because the fecal material needs to squeeze past the enlarged organ in the pelvic canal, the stools that are generated by dogs with BPH may also be notably flatter than normal. Castration is the treatment of choice for BPH because it removes the source of testosterone from the body.
Tumors Of The Prostate
Even though neutering does not have a substantial effect on prostatic tumors, I will provide a quick explanation of them here for the sake of completeness.
The growths that can form in the prostate have the potential to be highly aggressive, leading to a significant amount of tissue loss within the organ as well as frequently excruciating discomfort.
In the early stages, the symptoms may be similar to those of benign prostatic hyperplasia (BPH) or prostatic inflammation; in order to differentiate between these conditions, an ultrasound and tissue exams are required.
The outlook is typically not good for patients who have prostatic tumors since these cancers have a high risk of spreading to the bones of the lower spine.
Hernias
Herniation of the perineum is a problem that can be treated, although its prevention is preferable. This is a somewhat rare condition that only manifests itself in senior male canines who have not been neutered.
A rupture in the perineal muscles can occur as a result of the cumulative effect of testosterone on the muscles of the perineum (the region located between the tail base and the scrotum), as well as the enlargement of the prostate that occurs with advancing age.
These muscles are in charge of maintaining the standard position of the pelvic organs, such as the bladder, rectum, and prostate, so that they can function properly.
The rectum is frequently the first organ to herniate, which means that it typically slides beneath the skin of the perineum to form a sharp bend in the affected individual.
This bend makes it more difficult for the dog to eliminate his waste, which in turn causes him to exert himself more, which puts further strain on the hernia and causes it to get larger.
If the condition is allowed to persist for an extended period of time, what may appear to the owner to be a straightforward case of constipation might actually offer a significant obstacle for the surgeon to overcome when it comes time to perform surgery. Perineal hernias are notoriously difficult to repair, however, no two cases are ever exactly alike.
It takes a significant amount of skill on the part of the surgeon to replace the pelvic organs and repair the hole that is the source of the hernia without causing more damage, in particular to the big nerves that are located in the region. Castration is essential for the prevention of recurrence and must be performed in addition to the healing procedure.
Castration Performed For Behavioral Reasons.
We are able to treat or prevent inappropriate behaviors by removing the source of the testosterone that is causing them. These behaviors may be perceived as inappropriate in certain settings.
For instance, while it may be absolutely normal and natural for a male dog to seek to mount and mate with a female dog that is in heat, the exact same behavior may be entirely improper in a family with children, especially if the dog attempts to mount the children.
Neutering can significantly diminish or eliminate these sexual behaviors, as well as the roaming around in pursuit of in-heat females, which is common in intact males.
However, there is also a certain taught component, and it is considerably less likely that castration will abolish a behavior that an eight-year-old dog has spent a lifetime acquiring.
Castration is performed to remove testicles, which are the reproductive organs of dogs. The other kind of behavior that could be altered by the process of neutering is aggression, however, this won’t always be possible.
In cases of aggression, the involvement of a behaviorist is always valuable since it allows for the identification of the trigger for the behavior as well as the suggestion of cures for the behavior.
However, it is reasonable to generalize that dominance and territorial-type aggressions are more receptive to therapy with a combination of neutering and behavioral coaching. This is because these types of aggression are more closely related to social hierarchy.
It is essential to be aware of the fact that early sterilization makes the occurrence of these behaviors, in addition to the majority of the medical disorders described earlier, much less likely to take place in the first place.
When To Neuter Your Dog
The question of when the best time is to have an animal spayed or neutered is one that is frequently brought up in discussions among veterinarians and is by no means settled.
Neutering is safe and effective for the vast majority of male canines beginning at 6 months of age.
When deciding when to have a dog spayed or neutered, it is important to take into account a number of factors, including the dog’s breed, overall health, environment, and his behavior toward other dogs and people.
In order to prevent any unintended interference with their normal development, large and giant breed dogs are typically not spayed or neutered until they are around one year old.
This is done despite the fact that the vast majority of the evidence that is available suggests that this is not likely to be an issue.
Castration Technique
Castration necessitates the removal of both testicles by surgical means. The operation may typically be completed in very little time, but it does call for general anesthesia.
While the dog is under anesthesia, he is turned over onto his back and the hair around and in front of the scrotum is shaved and cleansed with an antiseptic solution.
The incision for the removal of the testicles is made directly in front of the scrotum by the surgeon, who then moves the testicles forward one at a time until they emerge through the opening.
It is possible to draw the testicle through the incision after a brief incision is made on the surface of the testicle itself. Once it is dragged through, its blood arteries and ductus deferens are clamped and knotted.
At this time, the testicle can be removed, and the blood vessels that were bound together can be allowed to retract back into the body.
After the dog has had both testicles removed, the skin and the subcutaneous tissues are closed, typically with multiple sutures, and then the dog is brought back from anesthesia.
Pain medication is given to all surgery patients as a matter of course, and the majority of castrated dogs make a speedy and uneventful recovery, exhibiting neither obvious pain nor distress.
When a dog is discharged from the hospital, which typically occurs later on the same day of surgery, its owners may be required to carry a supply of painkillers home with them if the dog is particularly sensitive or particularly little.
Castration is not a particularly difficult surgical procedure, and it almost never results in complications.
I would guess, based on years of experience, that over 90% are pain-free and want to be fully active within 48 hours following the treatment.
This might create a challenge, as rest is essential in the postoperative period in order to allow the incision to heal, therefore owners need to be prepared to keep their dog relatively confined for around the first week after surgery.
Alternative Options To Castration
Vasectomy is a different kind of surgical procedure that can be done to stop a male dog from having sexual relations with other females.
To perform this procedure, however, rather than removing the testicles, only a part of the ductus deferens needs to be cut.
As a consequence of this, the dog’s hormone levels have not changed, and all of the medical and behavioral issues that were previously mentioned continue to be a cause for concern.
Because of this, it is only occasionally used in modern times. In recent years, it has become possible to obtain a hormone disruptor known as deslorelin in the form of an injectable implant.
This implant is administered subcutaneously in dogs, and over the course of its active period of six to twelve months, it gradually releases the active ingredient that reduces the synthesis of testosterone and other hormones in the body.
Thus, it accomplishes many of the goals of surgical castration; however, care must be given not to forget to repeat administration before the effects wear off.
This is because it achieves many of the goals of surgical castration. Additionally, even after receiving the medication, it is possible that some of the dogs will go on to develop testicular tumors in the future.
Consequences Of Castration
When making arrangements for castration, there are two primary problems that should be discussed: weight increase and changes in the coat.
Because neutering both males and females lower their energy requirements, this means that for a given amount of food, a neutered dog is more likely to become overweight than an unneutered dog.
Neutering also reduces the risk of certain cancers. On the other hand, as a result of this, there is a widespread notion that all neutered dogs are destined to become overweight; this is not the case at all.
Either reduce the amount of food given to the dog or feed them a diet that is designed for neutered animals.
This should be started as soon as possible following the operation, and it is recommended that you have regular weigh-ins with your veterinarian or veterinary nurse for the first few months after the procedure.
Weight gain does not have to become a problem if adequate precautions and attention are taken. Neutering a dog of a certain breed can have an effect on the quality of its coat.
For instance, in the months after being neutered, spaniels frequently take on a “woolier” appearance than before the procedure.
This is a cosmetic issue that does not require any specific treatment; nevertheless, maintaining a high-quality diet and brushing your teeth on a regular basis will help to alleviate some of the symptoms.
Questions People Also Ask: (FAQs)
Do Male Dogs Change After Being Neutered?
Alterations in a Dog’s Behavior Following Castration or Neutering
When a man’s testicles are removed, they take with them the body’s primary source of testosterone. This leads to a reduction in sexually motivated behaviors in your dog, such as urinating in inappropriate places, running away to find other female dogs, and being aggressive against other male dogs.
If Male Dogs Are Neutered, Does It Increase Their Lifespan?
According to Austad and Hoffman, pets that have been spayed or neutered have lesser behavioral disorders and are less prone to infections, degenerative diseases, and traumatic or violent causes of death. As a result, spayed and neutered pets enjoy longer lives that are healthier and happier.
Do Neutered Dogs Have Balls?
In the first few days after surgery, the scrotum will frequently swell, which may cause some individuals to question whether or not the procedure was actually carried out.
If the dog is still young when the neutering procedure is performed, the empty scrotum will become less noticeable as the dog matures. If he is an adult when he gets the procedure done, the skin flap that covers the scrotum will be left intact.
When May I Take My Dog Out For A Walk After He Has Been Neutered?
How long will it be before we are able to take our dog on walks after he has been neutered? Following a surgical procedure, we typically recommend that you give your dog only a little exercise in the garden for the first 24 to 48 hours after the procedure.
Following this, we will recommend that they take brief walks on the leash until their post-operative checkup is scheduled.
When A Male Dog Gets Neutered, Is The Procedure Uncomfortable For The Dog?
The pain that is commonly associated with spay or neuter surgery is more of an annoyance than actual pain and may only persist for a few days; however, it should be totally gone within around a week. If you notice that your pet has been in pain or discomfort for more than a couple of days, it is in your best interest to seek additional guidance from your veterinarian.
