Dog neutering: what you need to know
Neutering is the surgical process of preventing your pet being able to reproduce. Male dogs are castrated and females are spayed. If you’re sure you don’t want your dog to reproduce, neutering will achieve this.
Why should I neuter my dog?
Aside from preventing an unwanted pregnancy and a litter of puppies, neutering your dog may have additional benefits:
- It can potentially decrease the risk of ovarian and mammary cancer in bitches, along with lowering the risk of certain prostate diseases and testicular cancer in male dogs.
- Castration may reduce aggressive behaviour in male dogs.
- For females, spaying reduces the risks associated with pregnancy and birth.
- Castrated male dogs are less likely to roam – and therefore less likely to get hurt, go missing, or be injured in a fight.
- Un-neutered dogs (especially male dogs) are more likely to be the target of aggression from other dogs.
- Neutering your dog helps to reduce the numbers of unwanted dogs, which takes a great deal of pressure off rescue centres that are always trying to rehome large numbers of dogs.
- Without the hormonal urge created by testosterone, a castrated male dog will be less likely to demonstrate his amorous intentions around your home – or on family members or visitors!
About the procedure
Dog neutering will be carried out by your local vet. Both dog castration and spaying are carried out under general anaesthetic. Whilst they are routine procedures, they are a major procedure, especially a spay, which involves entering your female dog’s abdomen. However, modern techniques are very safe.
Your dog will be given drugs to manage any pain and recovery is usually fast and straightforward – as long as your pet follows their post-operative instructions! Your vet can advise you on the best way to prepare your pet for the operation, and how you can help make their recovery as quick and painless as possible. These instructions are designed to make the process as easy as possible for you and your pet. The post-operative care is very important as well as the surgery itself.
What happens when a dog is neutered?
When a male dog is castrated, the vet removes both testicles to stop production of the male hormone testosterone. When a female dog is spayed, the vet removes the ovaries and usually the uterus so she can’t get pregnant.
Like most surgery, neutering involves some degree of discomfort but your dog will be given drugs to control the pain, and most are up and about soon after they’ve had their operation.
Some people believe it’s beneficial for female dogs to have a litter before they’re spayed but this is a myth. The risks involved with having a litter outweigh any potential perceived health benefits.
Female dogs can be spayed from a young age, generally around 6 months. Your vet will make the decision based on your pet specifically, their age and their breed.
Male dogs can also be neutered from around 6 months’ old, depending on their breed – again, your vet will advise. Dog castration is best carried out while your dog is young, as the benefits associated with castration start to reduce as they get older.
The cost of dog castration or spaying varies according to a number of factors, including the breed of dog you have. The weight of the animal also plays a major role in determining the cost. Your local vet will be able to advise you.
There is always some degree of risk with any anaesthetic, although modern techniques keep that to an absolute minimum. Urinary incontinence is sometimes associated with the spaying of female dogs, as is weight gain.
In rare situations, there is evidence of increase in tumour incidents and some forms of joint disease but at present, more often than not, the rewards outweigh the risks.
When it comes to neutering, always speak to your vet. They will be able to advise you based on your pet and your situation.
