The Ethics of Pet Spaying and Neutering: What the Experts Are Saying

In addition to routine pet vaccinations, many vets advise pet owners to neuter and spay their animal companions. This common practice aims to help reduce pet overpopulation and improve the health and behavior of individual animals.

However, some experts are now raising ethical concerns about spaying and neutering. They argue that the procedures are often performed without the animal’s consent and that they can have adverse physical and psychological effects on the animal.

Cat and dog neutering and spaying have been debated for many years. Some experts feel that the procedures are unnecessary and can cause health problems for animals, while many believe that they are a crucial part of responsible pet ownership.

This article explores the ethical debate surrounding pet spaying and neutering. It briefly discusses the benefits and drawbacks of the procedures from both a medical and ethical perspective.

What Experts Say About Spaying and Neutering of Pets

Firstly, the American Society for the Prevention of Cruelty to Animals (ASPCA) supports the spaying and neutering of all pets. They believe that the procedures are safe and effective, and they help reduce the number of homeless animals.

Similarly, the American Veterinary Medical Association (AVMA) agrees that spaying and neutering pets are generally in the best interests of the animal and society. They note that the procedures help to reduce the number of unwanted animals, which often end up in shelters or are euthanized.

Also, the Humane Society of the United States recommends spaying and neutering to help reduce pet overpopulation. They offer a low-cost spay/neuter program available in all 50 states.

However, some experts believe that spaying and neutering are not always in pets’ best interests. Dr. Laura J. Sanborn, author of “Long-Term Health Risks and Benefits Associated with Spay / Neuter in Dogs,” believes that the procedures can cause health problems for animals. She cites a study that found that spayed and neutered dogs are more likely to develop hip dysplasia, a condition that can cause joint pain and mobility problems.

Health Risks of Spaying and Neutering Pets (According to Science)

The debate surrounding the ethics of pet spaying and neutering is complex. There are a number of different factors to consider, including the health of the animal, the population of stray animals, and the personal beliefs of the pet owner.

First, let’s explore the health risks of spaying and neutering pets. Some experts believe that these procedures can cause health problems for animals, such as:

  • Neutering your dog early doubles the risk of hip dysplasia.
  • Spaying your female dog prior to their first heat cycle triples the risk of incontinence later in their life, according to the Royal Veterinary College (RVC).
  • Spaying and neutering can lead to weight gain and other health problems if not done properly.
  • Pets that are spayed or neutered are more likely to develop hypothyroidism.
  • Spaying female dogs before one year of age increases the risk of osteosarcoma – a type of bone cancer.

Benefits of Pet Spaying (According to Studies)

On the other hand, several benefits are associated with spaying and neutering pets. These benefits include:

  • Reduced number of homeless animals
  • A decrease in the number of animals that are euthanized each year
  • A decrease in the incidence of certain types of cancer
  • A decrease in the incidence of certain behavior problems

According to the study by Cornell Feline Health Center, an estimated 30 to 40% of all cats are affected by cancer. Similarly, the same study found that 50% of dogs over the age of 10 get cancer in their lifetime. However, spaying your female pet before a first, second, or third heat cycle reduces the hormones causing mammary gland tumors later in their lives. Studies show that spaying them before their 6th month reduces 91% risk in cats.

For male pets, neutering removes the region where testicular cancer grows, stopping it before it starts. It can also help prevent prostate infections and other forms of diseases involving that gland.


There’s no right or wrong answer for spaying and neutering your pet. You need to make a personal decision based on your own beliefs and values. However, you must educate yourself on the pros and cons of both procedures before deciding.

Make sure to discuss what is best for your furry friend with your dog and cat veterinarian before scheduling the procedure.
