When should you neuter a dog? BVA and BSAVA 2026

BVA and BSAVA recommend spaying most female dogs once they reach maturity, between 12 and 23 months depending on breed and expected age at maturity, and say castrating male dogs should be decided case by case, not before physical maturity for the breed unless there is a compelling reason. (BVA policy; VetClick, 3 March 2026.) This replaced the older one-size-fits-all advice, as our dog health hub explains. The BVA notes that neutering before six months is linked to a higher risk of some orthopaedic conditions, and that neutering female dogs reduces the risk of pyometra (a serious womb infection) and some tumours.

This is general information, not veterinary advice. Pawwala is not a vet. If you are worried about your dog, contact your vet.

Does pet insurance cover neutering?

No. Standard UK pet insurance does not cover routine care such as neutering (see what pet insurance covers). Some practice health plans give a discount: Medivet lists its Healthcare Plan neutering prices about 10% below standard, for example a dog spay from £248.40 instead of £276 at Medivet Coningsby. Our guide to health plans versus insurance explains the trade-offs.

What charities say neutering costs

Battersea's guide puts dog neutering at £200–£350, depending on breed, size and age (Battersea, updated 13 October 2026). That sits inside the practice range but below the large-dog prices. The PDSA includes neutering in its set-up cost for a dog: £415 for a small breed to £560 for a large one (PDSA, costs last calculated in 2024).

Plan the year

Neutering is a one-off cost in a puppy's first two years. Our cost of owning a dog guide adds it to the yearly costs, and the new puppy checklist covers the rest of the first year. For other vet prices, see the average vet bill, dog vaccination costs and cat spaying costs. The CMA published its final Order on 22 September 2026. Its first phase, which includes published price lists so owners know the cost of basic services such as consultations and vaccinations upfront, applies to larger vet businesses from 23 December 2026; smaller businesses have longer.
