What is spaying and neutering?

Spaying and neutering are surgical procedures that prevent dogs from reproducing:

• Neutering refers to male dogs, where the testicles are removed

• Spaying refers to female dogs, where the ovaries and usually the uterus are removed

In both cases, it’s a standard and common procedure. Your dog will be put under anaesthetic for the surgery, but rarely needs to be at the vet for more than a few hours. It’s usually fine for them to head back home the same day as the operation.

Should I get my dog neutered or spayed?

Choosing whether to get your dog neutered is a personal decision for you and your dog. The best thing to do is to talk to your vet, and fully understand what the benefits and risks of neutering would be in your dog’s case.

These can vary depending on the breed, size, health, pre-existing conditions, and temperament.

According to our recent data, 54%^{^} of our pet insurance customers have their dogs neutered.

Generally, neutering and spaying are very common procedures and are considered quite safe. Many people choose to have their dog neutered to fully avoid the risk of pregnancy, and to reduce the risk of developing certain health problems.

What are the benefits of neutering or spaying my dog?

There can be several health and behavioural benefits to neutering or spaying your dog:

Potential health benefits of spaying or neutering your dog

Spaying female dogs can reduce the risk of:

• womb infections (pyometra)

• ovarian cancer

• mammary tumours

Neutering male dogs can reduce the risk of:

• testicular cancer

• some prostate problems

Potential behavioural benefits of spaying or neutering your dog

Neutering may reduce some hormone-driven behaviours such as:

• roaming

• mounting

• urine marking

• certain forms of aggression

However, neutering is not a guaranteed solution for behavioural issues, and training may still be needed.

What are the risks of neutering and spaying my dog?

Spaying and neutering are considered safe and commonly performed procedures, but as with any surgery, there are some risks:

Possible neutering or spaying complications

• reactions to anaesthetic

• infection

• bleeding

• swelling after surgery

There can also be longer-term considerations. Some dogs may be more prone to weight gain after neutering, while certain larger breeds may benefit from delaying surgery until they are fully developed.

Your vet can help assess the risks and benefits based on your dog’s breed, age, size, and overall health.

Does it matter what age I spay or neuter my dog?

Yes. Research suggests the ideal age for neutering can vary depending on breed and size.

Some larger breeds may benefit from waiting until skeletal development is more complete, while smaller dogs are often neutered earlier. Timing can also depend on:

• sex

• behaviour

• lifestyle

• medical history

Your vet can advise on the best timing for your individual dog.

How do I get my dog neutered or spayed?

Talk to your vet if you want to get your dog neutered. They will be the ones to perform the procedure at their clinic, so they’ll be able to talk through the options, book the surgery, and advise you on how to prepare your dog for the operation and help them recover.

How much does it cost to get my dog neutered?

The Kennel Club says spaying or neutering can cost between £100 and £400. The cost of neutering a dog can vary depending on factors such as your dog’s size, sex, breed, age, and where you live in the UK.

For example, Henlow Vets currently lists the following prices for dog neutering and spaying:

Prices can vary significantly between veterinary practices, and female dogs are usually more expensive to spay because the procedure is more complex.

Some animal charities and local welfare organisations, such as Blue Cross, PDSA, and RSPCA may also help eligible owners with reduced-cost neutering.

Does pet insurance cover neutering or spaying?

Standard pet insurance policies usually do not cover neutering or spaying because they’re considered routine or preventative procedures.

However, some insurers may contribute towards the cost through wellness add-ons, preventative care packages, or multi-benefit policies.

Complications arising from the surgery may also be covered, depending on your policy terms and excess. Always check your policy wording carefully before arranging treatment.
