Desexing Your Dog


Neutering your dog is one way you can help to keep them healthy and prevent the arrival of an unexpected litter of puppies.  As there are already more dogs than homes, it is strongly recommended that everyone neuter their pet and include this in part of the budget of owning a dog.

Your vet will help you to work out the best time to desex your dog, but usually the procedure is done when he is around 6 months old. The surgery can be done as early as 8 weeks, and this is often the case with dogs in animal shelters.


Desexing has advantages for both genders. Entire male dogs will try and escape their yard in search of a lady friend, and this puts them at risk of being hit by a car or get into a fight. They may develop a number of medical conditions including testicular cancer and perianal adenomas. If he has an undescended testicle, it is more likely to become cancerous. Their tendency to urinate on things to mark them can make them unpopular with your family members.

Females also enjoy a number of health benefits associated with being spayed. They won’t suffer from a potentially fatal infection of the uterus known as pyometra, and depending on when the surgery is done, they may be at lower risk of developing breast cancer. Having a female dog come on heat twice a year can be inconvenient; she will bleed on your carpet and furniture and she will attract male dogs from far and wide. An unexpected pregnancy may see you with a bill for an emergency caesarean delivery, or you may need to bottle feed her pups if she doesn’t have any maternal instinct.


Your dog will need to be fasted before his surgery so he can have dinner as usual the night before, then no food or water for breakfast the next morning. This is to prevent him regurgitating food or liquid while he is under anesthesia which may then be inhaled, causing pneumonia.

If he is elderly, or if there are any concerns about his health, your vet will recommend blood tests before he is anesthetized.  This is just to make sure all is well with his internal organs.

Most dogs are able to go home on the same day as their surgery after they have fully recovered from the anesthetic, and this is when your hard work starts.  Good post-operative care is essential to allow your dog to recover quickly from his operation and avoid complications.

  • Offer your dog a small meal at dinner time, but don’t worry if he doesn’t want to eat anything. He may be feeling a little queasy. He should be more interested in food after about 24 hours.
  • Restrict his exercise for about 10 days, until his sutures are removed. This means no long walks, no running or jumping. Take him outdoors to the toilet on a leash. It?s not easy to do because he’ll be feeling good within a day or two of his surgery. A crate is a great help during this time.
  • If your vet has given you any medication for your dog, give them strictly as directed.
  • Don’t get your dog wet while he has sutures in. His wound needs to stay clean and dry.
  • Use an Elizabethan collar if he is licking or biting at his wound excessively.


As with any surgical procedure, there is the risk of complications. General anesthesia is very safe but some dogs will have an adverse reaction to it.

If your dog is too active, his surgical site and scrotum may swell. This is uncomfortable, but if own a female dog, too much activity is dangerous. If the abdominal sutures break down, she could develop a hernia and need further surgery to correct it.

Your vet will be available to you to answer any questions and ease your concerns after your dog’s surgery so if there is anything you are worried about, call them for advice.

With many benefits and minimal risks associated with neutering, any dog that isn’t to be used for breeding should have this procedure done.
