Pros and Cons of Neutering Your Labrador


Are you thinking of getting your Labrador neutered? Neutering your Labrador has a lot of benefits. However, it too puts your dog at certain disadvantages requiring you to be more vigilant in your care. While neutering lowers the risk of testicular cancer in dogs, it may increase the risk of obesity in him.

Benefits of Neutering Your Labrador

What is Neutering?

Neutering is medically known as orchiectomy. This procedure involves the surgical removal of the testicles of a male dog. It is also called sterilization, castration, or “fixing” a dog.

Neutering your Labrador has so many health benefits. It stops your Labrador from exhibiting unwanted behaviors, such as marking and aggression. However, it also has its disadvantages. You must consider the pros and cons of neutering your Labrador before doing it. Unless you do it at the right age, your Lab may face growth problems.

Benefits of Neutering Your Labrador

Calms Aggressive Dogs

Generally, Labradors are not aggressive. However, there may be instances when your dog shows food, territorial, or sexual aggression. When recurring, such behavior becomes a regular feature and your friendly dog turns a threat to kids and strangers.

Neutering your Labrador makes him calm and passive. Sex hormone testosterone is an important factor for causing aggression in male dogs. The testicles produce most of this hormone while the adrenal glands secrete it in small quantities.

You are removing the main source of testosterone by neutering your dog. This suppresses the foremost cause of aggressive behavior in your Lab. The difference in aggression becomes visible from 2 weeks to 6 months after the procedure.

Stops the Marking

Again, the production of testosterone in your Labrador’s body urges him to compete with other male dogs and mark his territory. While neutering does not fully stop your Labrador from lifting his leg on your furniture, it deters him from territorial marking. As a result, such behavior becomes suppressed.

Less or Zero Humping

Humping is a display of dominance or sexual tension. This behavior is also caused by testosterone. By neutering your Labrador, you can stop him from humping and mounting on you, your visitors, and your other dogs.

Lowers Risk of Testicular Cancer and other Testosterone-Induced Diseases

If your Labrador does not have testicles, he has no chances of suffering from testicular cancer. Apart from preventing testicular cancer, neutering your Labrador can also prevent him from developing testicular inflammation, epidydimal cancer, testicular torsion, epididymitis, testicular abscessation, and testicular trauma.

Reduce Chances of Producing Inferior Genetic Traits and Abnormalities

All dogs are beautiful no matter what they look like. But we have the choice to reduce the chance of producing puppies with congenital diseases and abnormalities.

Breeders do not breed Labradors for the sake of money. Most of them are passionate about developing the breed and making sure the offspring they produce are purebred and free from genetic problems. Responsible breeders get the dogs under their care screened for potential hereditary health issues. This allows them to know which dogs are good for breeding and lessen the chance of producing dogs that may develop hip dysplasia, elbow dysplasia, progressive retinal atrophy, and similar genetic problems.

Neutering your Labrador helps reduce the chances of unplanned breeding.

Reducing Stray Population

While neutering your Labrador does not directly help stray dogs, it does prevent him from accidentally impregnating strays. With the growing population of homeless dogs and those dogs who die in shelters simply because no one is there to adopt them, neutering your Labrador and not contributing to the increase in dog population is a big help.

Disadvantages of Neutering Your Labrador

Vulnerability To Become Obese

Neutering your Labrador can slow down his metabolic rate and thus, can make him obese. Studies have shown that to maintain a healthy weight, neutered animals only need around 25% fewer calories compared to intact animals. This means that if you are thinking of neutering your Labrador, then you must adjust his diet as well.

Inability To Pass Desirable Genetic Trait

Once you have your Labrador neutered, then he cannot breed anymore. This means that whatever desirable trait your Labrador has, he can no longer pass it. But if you do not really have plans to breed, then this is not a problem.

Growth Problems

Veterinarians say male dogs can be neutered as early as they turn 6 to 9 months old. For big dogs, such as Labradors, veterinarians recommend waiting until the dog reaches 2 years of age or until he is fully grown. The reason behind this is hormones play a vital role in the development and growth of dogs’ bodies. Some veterinarians report joint problems in dogs neutered early. In fact, a study by researchers from the University of California claims that early neutering can cause health problems in German Shepherds. The same group of researchers is planning to conduct the same study on Labrador Retrievers.

While neutering your Labrador has its benefits, there is a downside to it too. It is best to weigh down the pros and cons of neutering before making the final decision.


  1. All of the information available is very confusing. I have an 18 week old chocolate male lab and am looking at getting him desexed. The problem is, I have been given advice of áround 6 months’ and also ‘wait till around 18 months’ from 2 different vets at the same clinic!!!

  2. I think the whole point is, it’s better to wait for larger breeds unless there’s an immediate problem that could be solved by neutering like peeing on furniture or humping everything.

  3. Every Breeder I have talked to about neutering male labs Has told me to wait till they’re 18 months to two years old. I have a 5 yr old chocolate and added a 4 month old chocolate puppy to our family.. I’m going to play it by ear but would like to wait as long as I can.

  4. If you are thinking of MUTILATING your dog… DO NOT DO IT! Despite what MONEY GRABBING VETS will tell you it is a completely unnecessary proceedure and has no health or behavioural benefits.

  5. I’m worried about making the mistake of neutering my 14 month chocolate lab. I have booked an appointment for the end of the month. Now I’m thinking about canceling it and waiting until he’s two. He’s a real good dog who loves everyone but other dogs scent him and that’s the problem…they want to attack him even at times when he doesn’t try to hump. He gets depressed when he doesn’t get to socialize with other dogs.

  6. Please watch the video that veterinarian Dr. Karen Becker has on YouTube. It will help you decide what to do. Hope this helps.

  7. My Labrador is a bitch and I’m worried about her hormones and the physiological effects that spaying her will have on her,I’m worried if she gets really depressed

  8. Thank you so much for suggesting watching Karen Becker video! I have an 11 month old choc lab and was wondering the best time to neuter. I will definitely wait until 2 years old.

  9. I have had 5 labs all males my last 4 I raised 2 at a time they really need a buddy I have found. I never neutered my dogs and they were wonderful dogs very loving and did nnot ever have testicular cancer. And they were in fantastic shape they ate quality food and were never over weight I dint let my dogs run by themselves I never have a worry of them impregnating another dog I’m a very responsible dog owner. I feel lots of us are told to fix and vaccinate our dogs and it’s just not always necessary they are over vaccinated as well after there first year shots they need heartworm and possibly rabies vaccine but that is all I do vets need to earn a living and sometimes they over do it.

  10. our lab mix is 4 months old. He is rowdy and wants to bite all the time. We have a screened porch he can stay on during the day but I take him outside for exercise several times a day. When he comes inside the house, his mouth is open. We have given him all kinds of play toys and nothing seems to help. He sleeps in a huge dog wire cage inside our house. He’s been vetted and had shots needed and he eats super food………What else does anyone recommend to stop this biting behavior?
