Spay vs. Neuter: What’s the Difference?


Deciding whether to spay or neuter your pet is an important decision that affects their health, behavior, and overall well-being. While both procedures involve the surgical sterilization of animals, there are distinct differences between spaying and neutering, each with its own set of benefits and considerations. Understanding these differences empowers pet owners to make informed choices for their furry companions.


Spaying and neutering are surgical procedures that involve the removal of reproductive organs in pets, but they are specific to females (spaying) and males (neutering).

Spaying, typically performed on female animals, involves the removal of the ovaries and often the uterus. This prevents them from going into heat, eliminates the risk of certain reproductive diseases, and reduces the chances of unwanted pregnancies.

Neutering, commonly done on males, entails removing the testicles, which not only curbs the urge to roam and engage in territorial behaviors but also decreases the likelihood of certain health issues.

“This is Bob Barker reminding you to help control the pet population—have your pets spayed or neutered.”

You’ll undoubtedly know former presenter Bob Barker’s characteristic sign-off if you’ve ever watched The Price Is Right from beginning to finish. For decades, the fervent supporter of animal rights uttered the statement at the conclusion of each episode. After he departed in 2007, presenter Drew Carey carried on the custom.

There’s a strong possibility that even if you haven’t seen The Price Is Right, you’ve heard about spaying and neutering. Do you really understand the distinction between the two words, though? What is best for your dog, and how do you decide? 

The good news is that you’ve already made a choice in part. This is because only female dogs undergo the spaying process. Although the phrase “neutering” may theoretically refer to either gender, it is often used to refer to the desexing of male dogs. Both treatments sterilize the dog, preventing her from having pups.

And for both, your dog will need to wear an E-collar, sometimes known as “the cone of shame.” Continue reading to find out more about how the two treatments vary from one another and the general advantages they may provide for your cherished pet. 

What is Neutering?

When a male dog is neutered or castrated, the testicles are surgically removed by a veterinarian via an incision on the front of the scrotum. Neutering is a reasonably easy treatment that prevents your dog from having pups.

The operation will need your dog to be placed under anesthesia, but the whole medical procedure is normally brief, and you may usually take your dog home that same day to recover.

Although recovery usually only lasts a few days, you’ll need to avoid strenuous activities for around two weeks to ensure adequate healing, including jogging, jumping, climbing, and swimming. 

What is Spaying?

When a female dog is spayed, a veterinarian makes an incision in her stomach and conducts surgery while the animal is under anesthetic to remove her uterus and ovaries.

There are situations when laparoscopic surgery may be used for this operation. Even though it is more complicated than a neutering process, the procedure normally lasts less than 90 minutes.

Furthermore, most animals are okay to return home the same day to rest and recover, while some veterinarians may keep your dog overnight. For two to four weeks as she heals, she must refrain from leaping, running, roughhousing, and taking baths or swimming.

“Spays are much more complex than neuters,” explains Nellie Goetz, DVM, MPH, Executive Director of Altered Tails, a high-quality, high-volume spay/neuter facility that sees 22,000 patients annually.

“Spays include entering the abdominal cavity and cutting off the blood supply in a number of locations. They may have greater discomfort during the treatment than men do, and the recuperation time is often a little longer.

Why Should I Spay or Neuter My Dog?

The spaying or neutering of your dog has several positive health effects. According to research, spaying and neutering your dog lowers their chance of developing cancer, namely breast cancer in female dogs and testicular cancer in male dogs. Pyometra, is a uterine infection that often affects unspayed ladies. Additionally, neutered guys are less likely to get prostate problems.

Desexing may also assist with behavioral problems. Male dogs may become less aggressive and domineering by being neutered. Additionally, spaying will end your female dog’s cycle of heat. When she’s in heat, she could take risky actions to leave your house or yard in an effort to locate a mate. 

Most likely, your vet will reiterate that spayed or neutered pets have longer, healthier lives. 

Are Spaying & Neutering Expensive?

It costs money to get your dog spayed or neutered. Due to the complexity of the surgery, spaying is somewhat more expensive than neutering. In any case, you should budget $50 to $400 or more.

The cost depends on your particular dog, including his or her age, breed, and location. (For further information, see How Much Does It Cost to Spay or Neuter a Dog?.) Even while it could seem expensive to spend that much on a single operation, consider it a wise investment.

The expense of caring for a pregnant dog and her litter of puppies would be higher, not to mention any additional health problems that could develop in an unfixed dog. If lack of funds is preventing you from choosing to spay or neuter your pet, make careful to research low-cost clinics that provide treatments at significantly discounted prices.

Why should I consider spaying or neutering my pet?

Spaying and neutering offer various health and behavioral benefits. They prevent certain reproductive diseases, reduce the risk of certain cancers, and can help curb unwanted behaviors like roaming, aggression, and spraying.

At what age should I spay or neuter my pet?

The ideal age for spaying or neutering varies by species and breed. Generally, pets are spayed or neutered around 6 months of age, but consulting your veterinarian for guidance based on your pet’s individual needs is recommended.

Does spaying or neutering affect my pet’s behavior?

Yes, spaying and neutering can positively impact behavior. Spaying reduces the likelihood of heat-related behaviors and pregnancy. Neutering can minimize territorial marking, aggression, and roaming tendencies in males.

Are there any health risks associated with spaying or neutering?

Like any surgical procedure, there are risks involved, but they are generally low. The benefits of spaying or neutering often outweigh the potential risks. Your veterinarian can discuss the procedure’s risks and benefits specific to your pet.

Will spaying or neutering change my pet’s personality?

While spaying or neutering can modify certain behaviors, your pet’s core personality remains intact. They will still exhibit their unique characteristics and bond with you as they did before the procedure.

Can I spay or neuter my pet if I plan to breed them later?

If you have plans to breed your pet, it’s important to postpone spaying or neutering until you’re certain. Consult with a veterinarian or experienced breeder to determine the optimal timing for your breeding plans.

Do spayed or neutered pets require any special care post-surgery?

Yes, post-operative care is essential. Pets may need to wear a cone to prevent licking or biting at the incision site. Restricting physical activity and monitoring the incision for any signs of infection are also crucial.

Spaying and neutering play a crucial role in the responsible pet ownership journey. While they have their unique differences, both procedures contribute to the long-term health and well-being of your beloved companion. Consulting with your veterinarian and considering your pet’s individual needs will guide you toward the best decision for their future.
