Neutering: Neutering

Neutering is the general term used for the surgical removal of the reproductive organs in both male and female dogs.

• Castration is the removal of the testicles of the male dog.
• Spaying is the removal of the ovaries and uterus of the female dog.

It’s Nicer to Neuter – but why? There are lots of reasons, behavioural, medical and financial.


  • May encourage calmer, more predictable behaviour making the dog a more suitable family pet.
  • May help reduce aggressive and unwanted sexual behaviour, preventing fighting, mounting and destructives. Dogs that are neutered are also less likely to mark territory or stray.
  • Reduces the likelihood of strange behaviour in bitches coming into season (for about three weeks, twice a year).
  • Prevents male dogs desperately attempting to escape and seek out a local bitch in season.


  • Removes the significant health risks associated with pregnancy as well as the possibility of potentially fatal womb infections (pyometra).
  • Avoids the mess and inconvenience of seasons.
  • Reduces or removes the risks of some cancers in both male and female dogs (including testicular and mammary cancers).


  • Prevents the unnecessary costs of unplanned pregnancies and raising puppies.
  • Reduces likelihood of large vets’ bills associated with certain illness and accidents caused by unruly behaviour.

Dogs Trust offers a subsidised neutering scheme in specific regions in the UK, for those who receive means tested benefits.
