Dog Spaying and Neutering guidelines


The RSPCA’s dog neutering guidelines on the latest studies on the effects of neutering and spaying on health and behaviour.

Six months in bitches who are likely to be over 20kg when full grown
Four months in bitches under 20kg when full grown
Seven months in male dogs.
However it is important to discuss with your vet and a qualified behaviourist, when the most appropriate time for neutering would be for each individual.

There is also evidence to suggest that for anxious or fearful male dogs neutering may make their behaviour worse. For these dogs it is essential to discuss the right time to neuter with your  vet or a qualified behaviourist.

RSPCA Sussex North and Brighton Branch offers some heavily subsidised neutering for dogs, cats and rabbits for owners on named benefits or low incomes. Neutering is essential for a happy healthy life for your pet and prevents unwanted litters and animals ending up in rescue. We ask owners to contribute to neutering costs:

£75 for a dog spay, £55 for a dog castration

£25 for a cat spay, £20 for a cat castration

£5 for a rabbit spay/castration

Please contact us for help with neutering, by phone on: 01273 554218 – from 10.30am – 4pm daily.

As a charity we need to make our resources go as far as possible and the help we give is means tested.
