Female Cat and Dog Neutering (Spaying)

The age and timing of neutering female dogs is controversial and the data is conflicting. We recommend all female dogs that are not intended to be bred from are neutered (spayed) from 6 months of age. In large and giant breeds, we advise this procedure is undertaken between the first and second heats. To see if your dog is ready to be neutered please book in with one of our Nurses for a free 15 minute, pre-neutering health check.

Bitches often present later in life with reproductive problems (e.g. breast cancer or pyometra – pus in the womb) many of which are prevented or drastically reduced by early neutering. It has been showed that spaying bitches before their first season (ie. at 6 months of age) dramatically reduces the risk of breast cancer later in life.

Female cats come into season at around 5-6 months and are highly successful at finding a mate and coming home pregnant! Therefore, we advise neutering female cats at 4 months of age.

Did you know?

  • Neutered bitches live, on average, 2 years longer than those that are not!
  • It is a common misconception that female pets will be better after a litter of pups or kittens – this is an old wives’ tale and completely untrue.


We do not recommend the routine neutering (castration) of male dogs. There can certainly be benefits to castration including the reduction in wandering and general calming effect as well as health benefits in preventing testicular tumours and reducing problems with prostate. It is judged on an individual basis and typically performed once the dog is fully grown. The majority of related health problems that may occur later in life can be dealt with by castration at the time. For further advice about neutering your dog, please do not hesitate to speak to one of our vets.

  • All guide dogs and other working dogs are castrated.

Male Cat Neutering

Tom cats that are not pedigree stud cats should all be castrated at 4 months of age. The stray cat population in Britain is growing rapidly.

  • Neutered tom cats smell less
  • Neutered tom cats fight less
  • Neutered tom cats roam less

They are less like to acquire potentially serious infections such as FIV (Feline AIDS) or infected fight wounds and it reduces the risk of road traffic accidents through roaming. Castrating a cat will have no effect on his character.
