Neutering is the best way to prevent unwanted pregnancies, in both cats and dogs. But some owners may be anxious about making this decision on behalf of their pets. They may be concerned about possible behaviour changes, weight gain, or other health issues in their pet.

Even those owners who are convinced of the benefits of neutering may be unsure about the best time for their pets to have the surgery. They may also believe outdated advice that it is better for a female cat or dog to have a litter before being neutered, or to be neutered later in life.

Neutering is not a trivial procedure but the benefits outweigh the welfare implications. We strongly support the practice of neutering cats and dogs to prevent the birth of unwanted kittens and puppies, which can increase the stray population. Neutering also prevents the perpetuation of genetic defects.

Neutering should always be performed with adequate anaesthesia, and pain relief should be given to an animal pre- and post-operatively.

We recommend that pet cats are neutered from 16 weeks. In the case of feral and rescue kittens it may be necessary to neuter earlier due to the age of trapping.

BVA is currently considering the latest research on neutering and the potential health implications for dogs and bitches. In the meantime, we recommend owners speak to their vets about health and behavioural considerations in relation to neutering their dogs.

This position is due for review.
