Do Neutered Dogs Still Mate? Exploring the Myths and Facts of Canine Reproduction

When it comes to dogs and sex, there are many misconceptions and questions that arise. One of the most common ones is whether neutered dogs still mate. Some people assume that once a dog is neutered, it loses all interest in sexual activity or becomes physically incapable of reproducing. Others may wonder if neutering affects a dog’s behavior, health, or lifespan. To address these concerns and provide accurate information, this article will delve into what neutering means for male and female dogs, how it affects their sexuality and physiology, and what owners should expect after the surgery.

What is Neutering?

Neutering is a surgical procedure that removes a dog’s reproductive organs, namely the testicles in males (castration) or the ovaries and uterus in females (spaying). The purpose of neutering is to prevent unwanted pregnancies and reduce certain health risks associated with reproductive functions, such as cancer, infections, or behavioral issues. Neutering is usually done when a dog reaches puberty (around 6-12 months old), but it can be performed at any age. After the surgery, a dog’s hormone levels change, which can affect its body and behavior in various ways.

Do Neutered Male Dogs Still Mate?

The short answer is yes, neutered male dogs can still mate, but they cannot reproduce. Neutering removes the source of sperm production (the testes) but does not eliminate sexual behavior or desire. A male dog may still get aroused by other dogs’ scents or behaviors, mount them, hump them, or try to mate with them. However, since he has no viable sperm to fertilize a female dog’s eggs, mating serves no reproductive purpose. Moreover, some neutered male dogs may experience changes in their libido or aggression levels, depending on their age, breed, and personality. For example, some older dogs may become less interested in sexual activity or more prone to urinary problems after neutering.

Do Neutered Female Dogs Still Mate?

The short answer is yes, neutered female dogs can still mate, but they cannot get pregnant. Neutering removes the source of egg production (the ovaries) and eliminates the heat cycle (estrus), during which a female dog becomes receptive to mating and releases eggs for fertilization. However, neutering does not eliminate sexual behavior or attraction, and a female dog may still exhibit signs of mating behavior or even allow a male dog to mount her. This can be confusing or frustrating for owners who want to avoid accidental pregnancies or messy situations. However, it is important to note that neutered female dogs are less likely to develop certain reproductive health issues, such as mammary tumors or uterine infections.

How Does Neutering Affect Dogs’ Health and Behavior?

Besides reducing the risk of unwanted pregnancies and reproductive diseases, neutering has other potential benefits and drawbacks for dogs’ overall well-being. Some studies suggest that neutered dogs may live longer than intact dogs, especially if they are spayed before their first heat cycle. This could be due to the lower incidence of cancer, infections, or injuries related to reproductive organs or behaviors. Neutering may also reduce some forms of aggression, territorial marking, roaming behavior, and dominance struggles in male dogs. On the other hand, neutering may increase the risk of obesity, joint problems, and certain cancers (such as osteosarcoma) in some breeds or individuals. Moreover, neutering does not guarantee that a dog’s behavior will change significantly or permanently; many factors contribute to a dog’s temperament and training.

What Should Owners Do Before and After Neutering Their Dogs?

If you are considering neutering your dog, there are several things you should do to ensure the best possible outcome for your pet. First, consult with your veterinarian about the timing and type of surgery that suits your dog’s age, breed, health status, and lifestyle. Your vet may also recommend preoperative tests or medications to minimize risks and complications. Second, prepare your dog for the surgery by following the instructions provided by your vet, such as fasting, avoiding certain activities or substances, or providing a calm and comfortable environment. Third, monitor your dog’s recovery after the surgery by checking for signs of pain, infection, or abnormal behavior, and follow the postoperative care plan recommended by your vet. This may include restrictions on exercise, feeding, bathing, or medication.


In conclusion, neutering is a common and effective way to control canine reproduction and improve dogs’ health and behavior in many cases. However, it does not eliminate all aspects of sexual behavior or attraction in dogs and may have some potential risks or benefits depending on various factors. As an owner, it is important to educate yourself about neutering and its implications for your dog’s well-being before making any decisions. By doing so, you can provide the best possible care for your furry friend and avoid common myths or misconceptions about neutered dogs’ mating habits. And who knows?
