Neutering your dog: when to do it, recovery, myths and facts

Neutering is one of the most common operations in dogs. It is done under general anaesthetic and most dogs go home the same day.

Why neuter my dog?

• Females: no unwanted pregnancies, no seasons, protection from pyometra (a serious womb infection) and a lower risk of mammary tumours, especially if done early.
• Males: no risk of testicular cancer, fewer prostate problems, and often less marking and roaming.
• For everyone: fewer puppies ending up on the streets, a huge issue in Greece.

At what age?

There's no single right answer. Small dogs are often neutered at around 6 months. For large breeds, many vets prefer to wait until growth is complete. Discuss it with your vet based on your dog's breed, size and health.

Before the operation

Your vet will tell you how many hours of fasting are needed. A pre-operative blood test is often recommended, especially for older dogs.

Recovery (10–14 days)

• A protective cone or recovery suit so your dog can't lick the wound.
• A quiet life: lead walks only, no running, jumping or stairs, until your vet says otherwise.
• Check the wound every day. A little redness is normal.
• If you see swelling, discharge or bleeding, or your dog isn't eating or is very lethargic after 24 hours, call your vet.

Myths

• “She should have one litter first.” No. It has no health benefit.
• “His personality will change.” Your dog stays the same dog. Mostly hormone-driven behaviours change.
• “He'll definitely get fat.” Calorie needs drop slightly. With the right portions and exercise, he won't.

Frequently asked questions

How long does a dog take to recover from neutering?

Most are lively again in 1–2 days, but the wound usually needs 10–14 days to heal. Until then, keep things calm and use a protective cone.

Can a female dog be spayed while in heat?

Vets usually prefer to wait until the season has passed. Discuss the best timing with your vet.

Can an older dog be neutered?

Yes, after an examination and usually a blood test. Your vet will assess the anaesthetic risk.
