Neutering your pet has wide ranging health benefits and is an essential part of responsible pet ownership.

Some pet owners worry that neutering their pet will affect their personality. However, there is nothing to worry about - they will still be the same loving bouncy pet after being neutered. Your pet’s personality is influenced by so many factors including socialisation, training and interaction at home, so de-sexing won’t change them.

There are both behaviour and health benefits in desexing your pet.


The behavioural benefits are most relevant for male pets, but entire femaile pets can also show behaviour problems. Desexing your boy pet will help reduce unwanted behaviours such and dominance aggression, fighting, urine marking and wandering to find female companions. In female pets it can help reduce dominance aggression, particularly to other female pets in the same house when coming into season.


The health benefits of neutering apply to both male and female pets. For males, their risk of testicular cancer, prostate enlargement, infection and cancers is reduced or even eliminated. Prostate disease is very difficult to treat and often life threatening, so prevention is definitely the most effective treatment.

In female pets desexing prevents unwanted pregnancies. It also eliminates the chance of life threatening uterine infections (pyometra) which can occur any time your pet comes into season. It also drastically reduces their risk of breast cancer.

Some owners also worry their pet will put on weight after being desexed. However, so long as your pet is fed a balanced diet in the right proportion and gets regular exercise (which is essential for all pets  - desexed or not), their risk of weight gain is minimal.

We recommend desexing your pet between 3 and 6 months. After 6 months of age animals become sexually mature, which means male pets increase testosterone levels and females come into season for the first time. There is no evidence to suggest benefits to your pet's health or personality from letting them have their first season, give birth or mate.
