Spaying and Neutering: 

What Every Pet Owner Should Know

Spaying or neutering isn’t just about preventing litters—it’s about giving your pet a longer, healthier life. At Highbury North Pet Hospital in London, Ontario, we often speak with pet owners who are curious or concerned about spaying and neutering their pets. Whether it’s your first puppy or your fifth rescued cat, knowing when and why to schedule the procedure can make a big difference in your pet’s long-term health and behaviour.

This blog from an East London, ON vet explores the health and behavioural benefits of spaying and neutering, optimal timing, and how to care for your pet after surgery.

What Is Spaying and Neutering?

Spaying is the surgical removal of a female pet’s reproductive organs (ovaries and usually the uterus), while neutering refers to the removal of a male pet’s testicles. Both procedures are performed under general anaesthesia. 

Spaying and neutering are recommended by most if not all veterinarians as part of a responsible pet care plan. While the primary goal is to prevent unwanted litters, these surgeries also offer a variety of health and behavioural benefits that improve your pet’s quality of life. Just like parasite control, vaccines, and wellness exams, spay/neuter surgery helps keep pets happy, healthy, and safe. 

What Are the Benefits of Spaying and Neutering?

Spaying and neutering can lead to significant health improvements. For female pets, spaying eliminates the risk of uterine infections (such as pyometra) and greatly reduces the risk of mammary cancer. For males, neutering prevents testicular cancer and reduces the risk of prostate disease.

Behaviourally, spayed and neutered pets tend to be calmer and less prone to roaming, marking, or aggression. Males may show fewer signs of dominance or territorial behaviours. Females no longer go into heat cycles, which can be disruptive for both the pet and the household.

Additionally, spaying and neutering contribute to controlling the pet population and reducing the number of animals in shelters. Learn more about the benefits and reasons for spaying and neutering here. 

How Do You Know When To Spay or Neuter Your Pet?

Timing can vary based on the species, breed, and health of your pet. Generally, dogs and cats can be spayed or neutered by 5 and 6 months of age. However, for large-breed dogs, some vets may recommend waiting until physical maturity to reduce the risk of orthopaedic issues.

Your veterinarian will assess your pet’s health history, behaviour, and breed to determine when to spay or neuter. In some cases, rescue animals may be fixed earlier if recommended by shelter policies or health circumstances.

Is the Procedure Safe?

Yes—spaying and neutering are routine surgeries performed daily in veterinary practices. Like any surgery, there are risks associated with anaesthesia, but complications are rare when performed by an experienced team.

At Highbury North Pet Hospital, we use modern anaesthetic protocols, pre-surgical blood testing, and attentive monitoring to ensure the safety and comfort of your pet. However, it is important to monitor your pet after the surgery and watch for signs that something is wrong,  such as redness, swelling, discoloration, or foul smells at the incision site. Fever, lethargy, trembling, vomiting, and diarrhea are also warning signs. Contact your vet immediately if you spot any of these. 

How Long Does Recovery Take After Spaying or Neutering?

Recovery typically takes 10 to 14 days. Males heal faster than females: boys may only need a few days, while girls take a bit longer to recover. During this time, your pet should not be running, jumping, or playing roughly. You may be sent home with pain medications and an e-collar (cone) to prevent licking or biting at the incision site.

Most pets resume normal eating and behaviour within a day or two, but it’s important to follow your vet’s discharge instructions closely. You can find a helpful guide with info on both pre and post op care here. 

Will Spaying or Neutering Change My Pet’s Personality?

This is a common concern. It likely will, but don’t worry: in most cases, the change is positive. Your pet will still be the same loving companion, but may show fewer aggressive or hyperactive tendencies. Spaying and neutering doesn’t always make pets lazy, but they often do become more relaxed. This is a bonus, as pets are typically calmer and better behaved after.

Personality is shaped by many factors, including training, environment, and genetics. These surgeries remove hormone-driven behaviours that often cause stress or confusion in both pets and their owners.

Why Spaying and Neutering Matters

Beyond the health and behavioural benefits, spaying and neutering help reduce the strain on animal shelters. Pet overpopulation is a huge issue, and one that isn’t going away. Each year, thousands of homeless pets are euthanized due to overcrowding and lack of resources. By choosing to alter your pet, you’re helping curb this crisis.

In London, Ontario, local animal shelters and rescue groups rely on community support to promote responsible pet ownership and help with pet population control. Talk to your North London, ON vet about how you can help, whether through altering your pet or supporting spay/neuter awareness efforts.
