Neutering in Dogs: When to Do It, Benefits and What to Expect

Every good dog parent wants to know how to give their pup a long, happy and healthy life—and that usually starts when they are a puppy. Throughout those early days of teething, crate-training and learning how much to feed your puppy, there usually comes a time when a veterinarian will bring up the option of neutering in dogs. Whether or not to neuter your dog can be one of the first decisions a pet parent has to make, but it’s important to know all the facts first.

What Is Involved in Dog Neutering?

“Also known as castration, neutering means removing the testicles in male dogs in order to make them reproductively ineffective,” says Dr. Ivana Crnec, DVM, of “Today, with the advances in veterinary medicine, neutering is considered a routine procedure.”

As Dr. Crnec points out, it is an extremely common procedure, with the American Kennel Club (AKC) estimating 80 percent of US dogs to be fixed—either neutered or spayed depending on the dog’s gender.

When Are Dogs Neutered?

While it is most common to neuter male dogs between 6 months and 2 years of age, size of the dog, breed, behavior, and other considerations may cause your veterinarian to recommend an early or delayed neuter procedure. For some large-breed dogs, for example, vets recommend that the procedure is done later, when the puppy is older so that the testosterone has more time to help with bone and joint growth and development.

“Neutering is not age-limited and can be done much later in life,” Dr. Crnec says. “For example, a dog used in breeding programs can be neutered once they leave the program, or a stray dog can be neutered when homed or placed at an animal shelter or foster.”

Benefits of Neutering

By limiting the likelihood of pet pregnancy, dog parents can more responsibly care for their pets, and breeding can be left to AKC certified breeders with expertise.

Beyond pregnancy prevention, there are myriad reasons to neuter a dog, including health and behavioral benefits.

Other benefits of neutering include:

● Reduces the risk of testicular cancer, prostate disease and tumors
● Reduces the urgency or desire to “roam” in pursuit of females in heat, resulting in less injury due to fights or accidents (such as hit by car)
● Can help curtail certain behavioral problems, such as urine marking, leg humping and more

All About Dog Neutering Surgery

Risks of Neutering a Dog

“The risk associated with neutering is minimal,” Dr. Crnec explains. “In fact, the anesthesia-related risk is greater than the risk associated with the procedure itself.”

Dr. Crnec adds that pet parents should “always talk to your vet regarding the overall health of the dog and whether there is a factor increasing its anesthesia risk.” Current physical examination (to check for heart murmurs or other health concerns) and pre-anesthetic bloodwork is a good way to evaluate your pet’s overall health and determine if they can undergo anesthesia safely.

While post-operative complications are typically uncommon and minimal with neutering procedures, if you notice any of the following concerns, call your veterinarian immediately:

  • Hemorrhage (bleeding)
  • Infection
  • Wound breakdown (dehiscence)

Dog Neutering Costs

The cost of a typical neutering procedure varies greatly, based on the geographic region and type of practice/veterinarian doing the surgery.

The cost of a neutering a dog at a private practice animal hospital or veterinary clinic averages about $200-500 per Forbes Advisor 2023. Cost conscious pet parents may be able to find a lower-cost option in their area through spay/neuter clinics or with state voucher programs/assistance. Organizations like SpayUSA and the ASPCA offer searchable listings to help pet parnets find low-cost spay and neuter services near them.

Traditional pet insurance only covers pet accidents and illness, so it does not typically cover neutering. However, some preventative care plans, which offer wellness coverage for routine veterinary costs, do cover the procedure. Chewy’s CarePlus, for example, offers both types of plans.

Neutering Procedure for Dogs

“In layman’s terms, neutering entails removal of the testicles, [but] medically speaking, the procedure is called orchiectomy, from the Greek word orchis, meaning testicle,” Dr. Crnec explains.

During this procedure, both testicles of an intact male dog are surgically removedbut the scrotum is typically left behind. Immediately post-surgery, it may look like a dog still has testicles due to swelling in the area and the remaining scrotum, but the scrotum should shrink over time.

Neutering Aftercare for Dogs

Because neutering is a surgical procedure, dogs will have to take it a little slow post-surgery.
“It is important to keep dogs calm and limit their activity for 10-14 days after the procedure,” Dr. Crnec says. That means different things for different dogs, so follow your veterinarians aftercare instructions for your specific pet.

Additional instructions will liekly include taking extra care to ensure the incision is kept dry, which means “no bathing, swimming or playing in deep snow.” Dogs may also benefit from wearing an Elizabethan collar, aka a cone collar, to protect the incision site and allow it to heal.

Neutering a Dog: FAQ


Does neutering calm a dog down?

A:It’s a common theory that neutering your male dog can calm them down, and while that can be true for many, Dr. Crnec says not necessarily. “Some pet parents report a more chilled behavior in their dog after neutering, but that is not always the case.”


Spay/neuter: what’s the difference?

A:Though these words are often used interchangeably, they refer to two different surgical procedures. Animals who are “fixed,” meaning that they have undergone a surgery so that they cannot reproduce, are either spayed (in female dogs) or neutered (in male dogs).


What should a dog look like after neutering?

A:You pet will likely be sleepy for 12-24 hours after their procedure. After that your vet may send home medication to help them heal and rest. It is typically recommended to monitor the incision site at least once daily for excessive redness, swelling, or discharge. If noted or concerned, please contact your veterinarian.
