How Much Does It Cost to Spay a Dog? Cost by State

Spaying a dog averages $455 in the US and neutering $487, but the state you live in moves that by hundreds of dollars, and a nonprofit clinic can do the same surgery for $65. Pick your state below for the local average and the cheaper routes.

How much does it cost to spay or neuter a dog?

Across the US, the average is $455 to spay and $487 to neuter, with most people paying somewhere between $361 and $885 depending on where they live and which clinic they use. Those figures come from a 2025 study of actual procedure costs, covering all 50 states and DC.

The state spread is large:

A Hawaii spay costs more than twice a West Virginia one. The calculator above has all 51 figures.

An oddity in the data worth flagging

In this dataset, neutering comes out more expensive than spaying in every single state. That is the opposite of what many individual clinics charge, because a spay is abdominal surgery and a neuter usually is not, so the spay is normally the pricier of the two.

We have published the figures exactly as the study reports them rather than quietly “correcting” them. The practical lesson is the same either way: these are population averages, not a price list, and the only number that matters to you is the written quote from the clinic you choose.

Low-cost clinics charge a fraction of this

This is the part most cost articles bury. Nonprofit and municipal spay/neuter clinics perform the same operation, with licensed veterinarians, at a fraction of private-practice prices. Real published examples:

Those are specific clinics rather than a national rate, but the gap is real and it is enormous. Where to look:

• The ASPCA’s low-cost clinic database, searchable by zip code.
• Your local humane society or SPCA, which often runs subsidised days or vouchers.
• Veterinary teaching hospitals, where supervised students operate at reduced cost.
• Municipal programmes, since many cities subsidise sterilisation to reduce shelter intake.
• Breed and rescue groups, which sometimes hold voucher programmes.

What the price should include, and what gets added

Two quotes for “a spay” can mean quite different things. Before you book, ask which of these are inside the price:

• the pre-surgery physical exam
• pre-anaesthetic bloodwork, if recommended
• anaesthesia and monitoring during surgery
• pain medication to take home, not just the dose given in the clinic
• a cone or recovery suit
• the post-operative check and any stitch removal

An office-visit fee is commonly charged on top of the procedure. Larger dogs often cost more than small ones, because anaesthetic is dosed by weight and the surgery takes longer.

Is it worth it?

Set against the cost: an unplanned litter means several weeks of care, vaccinations and finding homes, and a pyometra, the womb infection that unspayed females are at lifelong risk of, usually means emergency surgery at a far higher price than a planned spay. Our dog heat cycle guide covers that risk and its warning signs.

When to do it is a separate question from what it costs, and the timing genuinely varies by breed and size, with trade-offs around joint and cancer risk that are still debated. That one is worth a conversation with your own vet rather than a rule from the internet.
