Dog Castration
Cost UK
Dog castration (male neutering) costs £150 to £300 in the UK in 2026. Price depends mainly on dog size — smaller dogs cost less due to shorter anaesthesia time and smaller incisions.
What You Will Pay
Castration is one of the most common surgical procedures performed on male dogs in the UK. It prevents unwanted breeding, reduces certain behavioural issues, and eliminates the risk of testicular cancer. The procedure is routine and recovery is typically straightforward.

Factors That Affect
the Price
Dog size
The biggest factor in castration cost is dog size. Larger dogs need more anaesthesia, longer surgical time, and more post-operative medication. Giant breeds can cost over double a small dog.
Location
London and South East practices charge 20-40% more than Northern England, Scotland, and Wales. A medium dog castration costs £250-£300 in London versus £180-£220 in the North.
Cryptorchid (undescended testicle)
If one or both testicles are retained in the abdomen, the surgery is more complex (essentially abdominal surgery) and costs £300-£600. This should still be done as retained testicles have a high cancer risk.
Age
Most vets recommend castration at 6-12 months. Older dogs may need additional pre-operative screening. Very large breeds may benefit from delayed neutering (12-18 months) to allow full skeletal development.
How to Save Money
Check charity subsidies
Dogs Trust, PDSA, Blue Cross, and many local charities offer subsidised or free neutering for eligible owners. The Dogs Trust has neutered over 100,000 dogs through their subsidised scheme.
Compare local prices
Castration prices vary by £50-£100 between practices in the same area. Get quotes from at least 3 vets before booking.
Ask about package deals
Some practices offer neutering packages that include the surgery, pre-op blood test, microchip, and post-op check at a bundled discount.
Buy post-op medication with a prescription
Post-operative pain relief (Metacam/meloxicam) is cheaper from online retailers. If your dog needs more than a few days' supply, ask for a prescription.
Would insurance have covered this?
On a typical lifetime policy an owner pays the excess (usually £60–£200) and, on some policies, 10–20% of the rest. Pre-existing conditions are never covered, so the time to compare is before something goes wrong.

Frequently Asked Questions
Dog castration costs £150-£300 in the UK in 2026, depending primarily on dog size. Small dogs (under 10kg) cost £150-£200. Medium dogs (10-25kg) cost £180-£250. Large dogs (25kg+) cost £220-£350.
Most vets recommend castration at 6-12 months. For large and giant breeds, some evidence suggests waiting until 12-18 months to allow full skeletal development. Discuss timing with your vet.
Castration prevents unwanted puppies, eliminates testicular cancer risk, reduces prostate problems, and can reduce roaming, marking, and some forms of aggression. It is also required by many dog daycare and boarding facilities.
Most dogs recover within 7-10 days. They need to wear a buster collar to prevent licking, have restricted exercise for 10-14 days, and attend a post-op check at 3-5 days and 10-14 days.
The Dogs Trust offers subsidised neutering for owners on certain benefits. PDSA provides free neutering for eligible owners. Local councils and charities also run schemes. Check eligibility online.
