How Much Does It Cost to Spay or Neuter a Dog or Cat?
At a full-service private veterinary practice, the national average cost to spay a dog is $455 and to neuter a dog is $487, with typical ranges of $361 to $829 and $385 to $885, per a 2025 veterinary procedural-cost study as reported by one pet insurer. For cats, a private-practice spay generally runs $300 to $500 and a neuter $200 to $400, while low-cost and nonprofit programs perform the same core surgery for roughly $50 to $150 for a cat spay and $35 to $150 for a neuter. That last gap (the same operation at a fraction of the price) generates most of the questions owners ask about this surgery. So this guide covers the whole picture: what spaying and neutering cost in 2025–2026, why the range is so wide, why low-cost and nonprofit programs can charge so much less without cutting surgical corners, and how to plan for the bill.
The numbers at a glance
Two things are true at once about the table below: the averages are real, and your quote may still land outside them, because every practice sets its own prices and every pet brings its own variables. For cats, a second insurer’s guide (referencing 2025 MarketWatch veterinary pricing) lands in the same neighborhood: around $300 to $400 for a spay and $200 to $300 for a neuter, which is about as close to consensus as veterinary pricing gets.
| Full-service private practice | Low-cost and nonprofit programs | |
|---|---|---|
| Dog spay | $455 national average; typical range $361–$829 | Usually under $300; one published nonprofit price list: $110 income-qualified, $310 standard |
| Dog neuter | $487 national average; typical range $385–$885 | $100 income-qualified, $280 standard on the same list |
| Cat spay | Roughly $300–$500 | Roughly $50–$150; $77 including vaccines on that list |
| Cat neuter | Roughly $200–$400 | Roughly $35–$150 |

Why the range is so wide
Start with geography. The same insurer’s 2025 pricing guide found the average dog spay runs about $874 in Hawaii versus roughly $390 in Mississippi (more than a two-to-one spread for the identical procedure), and lists the biggest price factors as the dog’s size and weight, the type of facility, geography, health status, and age.
Then add the pet on the table. One pet-health publication’s 2025 guide puts a routine dog spay at a private practice anywhere from $250 to $2,000, a range it attributes to one insurer’s data, and explains what moves the meter: bigger, older, and overweight dogs need more anesthesia and longer surgical time; a dog that is in heat or pregnant is a more involved surgery and costs more; a laparoscopic spay costs more than the traditional technique; and pre-anesthetic testing and the local cost of living shift the total too. At low-cost clinics, the same guide notes, you’ll usually pay less than $300 for a dog spay. Treat the national ranges as your bracket and ask for an itemized local quote.
Why is it so much cheaper at a nonprofit clinic?
This is the question behind the question, and the honest answer has two halves — neither of which is “someone is doing it wrong.”
The first half is specialization and volume. The AVMA reports that a veterinarian at a typical high-quality, high-volume spay-neuter clinic may do as many as 60 surgeries in a day, and that research shows these surgeries, performed to veterinary guidelines, “can be done quickly and at a high standard without compromising patient health or welfare.” A surgical team that does one operation all day, every day, gets extraordinarily efficient at it. That efficiency, plus nonprofit funding and income-qualified pricing, is what the low sticker price reflects. It is a different service model, not a lesser surgery.
The second half is what’s on the bill. As one cat-health publication puts it, low-cost procedures often “don’t entail all of the recommended extras that you would get from your regular veterinarian, such as pre-anesthetic bloodwork and an IV catheter and intravenous fluids”, and extra charges can apply if a cat turns out to be pregnant or in heat.
You can see the whole model clearly in one Florida nonprofit clinic’s published price list, effective June 1, 2025: cat spay or neuter for $77 including vaccines ($45 for feral cats), dog spays at $110 income-qualified or $310 standard, dog neuters at $100 or $280, plus surcharges of $25 for a dog in heat or pregnant, $50 to $200 per testicle for an undescended (cryptorchid) testicle, $50 extra for dogs over 90 pounds and $100 over 125 pounds, $15 for flat-faced breeds, and required $125 bloodwork for pets eight years and older. Two lessons hide in that list. The base price is a starting point, not a guarantee. And the same medical realities (weight, age, anatomy, being in heat) move the price at every kind of clinic, because they change how hard the surgery is. If a nonprofit or shelter program fits your budget, use it without a moment’s guilt; these programs do enormous good. Just check the current rules, whether you qualify for the lower tier, and exactly what the quoted price includes.
What the higher price at a full-service practice buys
Mostly, it buys the things wrapped around the scalpel. The AVMA’s guidance on anesthesia for pets describes what full anesthetic care looks like: a thorough physical exam first, often pre-anesthetic blood tests to check for “any indications of a developing medical problem or anesthetic risk,” and an intravenous catheter “usually placed to allow administration of fluids and medications.” During surgery, the AVMA describes monitoring “comparable to what you’d receive if you underwent anesthesia”: an endotracheal tube delivering anesthetic gas and oxygen, IV fluids supporting circulation and blood pressure, pulse oximetry, blood-pressure and temperature monitoring with warming blankets, and ECG, with close monitoring continuing through recovery. The same guidance offers real reassurance about the risk itself: “Most healthy pets—even senior pets—don’t have any problems with anesthesia and, in general, the risks are more closely related to the procedure being done and your pet’s general health than to the anesthesia itself.”
That paragraph doubles as a shopping checklist. Wherever you book (private practice or nonprofit program), ask which of these the price includes: pre-surgical exam, pre-anesthetic bloodwork, IV catheter and fluids, dedicated anesthetic monitoring, pain medication to go home, and a recheck. It’s also the standard we’re designing our own spay and neuter service and surgical care around.
The other side of the math
The cost conversation is incomplete without what the surgery prevents. The AVMA notes that spaying “can prevent uterine infection and reduce the risk of breast cancer,” and that spayed or neutered dogs and cats “live longer, on average, than other dogs and cats.” A national animal-welfare organization is more specific: spaying prevents uterine infections and decreases the incidence of breast tumors (which are malignant in about 90 percent of cats and 50 percent of dogs), with the best protection coming from spaying before the first heat, while neutering prevents testicular cancer and some prostate problems. There’s a quality-of-life line item too: the same organization notes an unspayed cat in season goes into heat four to five days every three weeks during breeding season, with all the yowling and escape attempts that implies. A planned procedure on a young, healthy pet is the least expensive version of this surgery you will ever be quoted; the unplanned alternatives, a life-threatening uterine infection (pyometra) that ends in emergency surgery or an unexpected litter, arrive on their own schedule.
Timing changes the bill
For cats, the guidance is unusually unified: the AVMA supports spaying or neutering cats by five months of age, and animal-welfare guidance notes the surgery is generally considered safe for healthy kittens as young as eight weeks, ideally done before five months. For dogs, the AVMA says plainly that there is no one-size-fits-all recommendation: timing should be decided with your veterinarian based on breed, age, sex, personality, and health. Six to nine months is the traditional age for puppies, with healthy puppies eligible as young as eight weeks; for large breeds, many veterinarians suggest waiting until growth is finished, so ask what’s right for yours. Timing is also a cost lever: since price climbs with weight and age (and in-heat or pregnant surgeries cost more), settling the schedule early with your veterinarian usually means a smaller bill. Whenever you book it, the aftercare is the same: the AVMA notes your pet will be kept comfortable and asleep under general anesthesia with medications to minimize pain, and your job afterward is to keep them calm and quiet as the incision begins to heal; expect your veterinary team to ask for roughly 10 to 14 days of restricted activity and a cone or recovery suit to keep the incision untouched. Call your veterinarian promptly (or the nearest veterinary emergency provider after hours) if you see the incision opening or discharging, active bleeding, swelling that keeps growing, repeated vomiting, refusal to eat past the first day, or unusual lethargy.
Budgeting for it
If a puppy or kitten just joined your family, this surgery belongs on the year-one budget alongside vaccines and exams; our first-year checklist maps those costs out, and our guide to what a vet visit costs covers the routine side of the ledger. Don’t count on insurance for this one: as we covered in our pet insurance vs. wellness plans guide, accident-and-illness policies are built for the unpredictable and generally exclude planned, routine care, though some wellness plans and add-on riders reimburse part of it, so read the specific plan and do the arithmetic. Beyond that, the playbook is simple: get an itemized quote, ask what’s included and what triggers a surcharge, and ask about payment options (Agave plans to accept CareCredit once we open).
Where Agave will fit
Agave Animal Hospital is an independently owned practice being built in St. George now, expected to open in early 2027 — we are not open yet, and nothing above should be read otherwise. When we do open, spay and neuter surgery here will work the way this guide describes the full-service tier: a pre-surgical exam and pre-anesthetic bloodwork, an IV catheter, monitored anesthesia, multi-modal pain management, and a recheck, with an itemized estimate in your hands before surgery, not after. Because we’re independent, Dr. Nicole Sorensen and the doctors treating your pet also set the prices, and plain talk about costs is part of the design. You can follow our progress on our opening page, and if you’d like to be among our first patients, join the opening list.
The bottom line
Expect roughly $455 to spay a dog and $487 to neuter one at an average private practice, $300 to $500 for a cat spay and $200 to $400 for a cat neuter. And know that low-cost and nonprofit programs deliver the same core surgery for far less by specializing, running high volumes, and quoting a leaner package. Neither tier is a trick; they are different service models, and the AVMA’s own reporting backs the quality of well-run high-volume programs. Wherever you go, ask the same three questions: what exactly is included, what could add a surcharge, and what will the total be in writing. The cheapest version of this surgery is the one you plan: young pet, healthy weight, scheduled at the age your veterinarian recommends (before the first heat for cats and many dogs), at whichever door fits your budget.
Frequently asked questions
How much does it cost to spay a dog?
At a full-service private practice, the national average is $455, with a typical range of $361 to $829 per a 2025 procedural-cost study — and one pet-health publication's guide stretches the full private-practice range to $250 to $2,000 depending on size, age, technique, and region. Low-cost and nonprofit programs usually charge less than $300, sometimes far less with income qualification. Size matters more than most owners expect: a large dog needs more anesthesia and longer surgical time than a small one.
How much does it cost to neuter a cat?
Per 2025–2026 published fee guides, expect roughly $200 to $400 at a full-service private veterinary practice, while low-cost and nonprofit programs typically charge about $35 to $150. A cat spay runs higher (roughly $300 to $500 at a private practice) because it is abdominal surgery, while a neuter is a shorter, simpler procedure. Ask any provider for an exact quote and a list of what the price includes.
Why is spaying cheaper at a low-cost clinic than at a vet?
Two reasons: volume and inclusions. High-quality, high-volume spay-neuter programs specialize: the AVMA notes a veterinarian at such a clinic may perform as many as 60 surgeries in a day, and research shows the work can meet a high standard, so each surgery costs less to deliver. The quoted price also usually covers fewer line items: extras like pre-anesthetic bloodwork, an IV catheter, and IV fluids are commonly part of a full-service package but not a bare-bones one, so compare what each price actually includes.
Does pet insurance cover spay or neuter surgery?
Generally no — standard accident-and-illness policies are built for unpredictable problems and typically exclude routine, planned care, and a scheduled spay or neuter is the definition of planned. Some companies and practices sell wellness plans or add-on riders that reimburse part of the cost, so read the specific plan before counting on it. The honest test is arithmetic: compare what the add-on costs against what it would actually pay toward the surgery.
Does it cost more to spay a dog in heat or pregnant?
Yes — a dog that is in heat or pregnant is a more involved surgery, and published guides note the price rises accordingly; one nonprofit clinic's published price list adds a $25 surcharge for exactly this, and published guides note extra charges can apply at other clinics too. Pregnancy or heat can also turn up as a surprise mid-surgery charge if it wasn't known beforehand. Scheduling the procedure before the first heat, or between cycles, usually avoids the extra cost; ask your veterinarian about timing.
What age should I spay or neuter my dog or cat?
For cats, the AVMA supports spaying or neutering by five months of age, and animal-welfare guidance notes the surgery is generally considered safe for healthy kittens as young as eight weeks. For dogs, the AVMA says there is no one-size-fits-all answer — timing should be decided with your veterinarian based on breed, age, sex, personality, and health, and many veterinarians suggest letting large breeds finish growing first. Six to nine months is the traditional age for puppies, with healthy puppies eligible as young as eight weeks.
