Dog neutering

Neutering is a simple operation that will stop unwanted pregnancies and benefit their overall health and wellbeing.

When should my dog be neutered?

The age at which a dog should be neutered differs depending on breed type; it is advisable to contact your vet to discuss neutering as soon as possible.

Benefits of neutering – why should my dog be neutered?

Health and welfare

  • Unneutered male dogs are at a higher risk of testicular tumours
  • Neutering also helps to prevent the onset of prostrate conditions which are common in unneutered dogs
  • Unneutered female dogs are at a higher risk of developing mammary tumours
  • Neutering also removes the threat of womb infections which can be very serious
  • Allowing a dog to have puppies puts extra pressure on rehoming organisations that are constantly struggling to keep up with the amount of unwanted dogs arriving each day.


  • Unneutered female dogs will come into season approximately twice per year, you will notice blood spots where your dog walks, and particularly in her bedding
  • The changes in hormones of dogs in season can change their behaviour; female dogs may be pestered by persistent male dogs while unneutered male dogs may escape or run away on walks when trying to look for a mate
  • Neutering can remove some of the undesirable behaviour in male dogs such as scent-marking or humping.

Neutering isn’t the only way to benefit a dog’s behaviour - consistent positive training with your dog is also strongly advised.

How much does it cost?

The cost of neutering differs for the breed, size and age of your dog. You should speak to your vet regarding costs.

A number of organisations provide discounted or free neutering such as Blue Cross, The Mayhew Animal Home and RSPCA.

Where can I get my dog neutered?

You can contact your vet to organise neutering of your pet.

Dispelling the myths surrounding neutering

Will my dog get fat if I have him neutered?

There is no evidence to support this. With an appropriate diet and plenty of exercise there is no reason why your dog will put on weight. It is possible that your pet will require less food than before neutering, but your vet will advise on this.

Isn't it good to let your female dog have a litter of puppies before neutering?

There are no documented health benefits associated with this. Young mothers are at greater risk of complications during the delivery of their puppies. Pregnancy presents more of a risk than neutering.

Will neutering my dog make him better behaved?

While there are some behavioural benefits to neutering, such as the elimination of behaviours such as scent marking and humping, neutering is not a quick fix for behavioural issues in dogs. It is important to spend time and patience on training your dog using positive reinforcement.
