Spaying — an ovariohysterectomy — costs roughly $250 to $1,200, depending far more on what is included than on the surgery itself.
That spread confuses people, and it should. Two clinics quoting five times apart are usually performing the same operation. What differs is the safety margin around it.
What the price difference buys
The surgery is standard. These are the items that move the number:
- Pre-anaesthetic bloodwork, which checks liver and kidney function before drugs that rely on both
- Intravenous fluids running throughout, supporting blood pressure under anaesthesia
- A dedicated nurse monitoring the patient rather than a shared one, with blood pressure, capnography and ECG
- Multimodal pain relief during and after, plus medication to go home with
- The cone, the recheck and the suture removal — sometimes included, sometimes billed separately
- Laparoscopic technique, offered by some practices at a premium, with smaller incisions and less post-operative discomfort
High-volume, low-cost clinics do genuinely good work and they exist for an excellent reason: an affordable spay is better than no spay. What you are buying at the higher price is monitoring depth and margin for the unexpected, which matters more in an older, heavier or unwell animal than in a healthy young one.
Ask for an itemised quote. Any good practice will give you one, and the conversation tells you a great deal.
The best age question
The old advice was six months for everyone. That is no longer the advice for large and giant breeds.
Several studies now link early neutering in larger dogs to higher rates of cranial cruciate ligament rupture, hip dysplasia and certain cancers. The sex hormones play a part in closing the growth plates, and removing them early changes how the skeleton finishes growing.
Practically, this means:
- Cats: the traditional timing holds. Spaying before the first season is standard and well supported.
- Small dogs: the traditional timing holds too.
- Large and giant breeds: many vets now recommend waiting until closer to skeletal maturity, often 12 to 24 months.
This is a genuine conversation to have about your specific dog, not a rule to look up. Breed, size, temperament, your household and whether you can reliably manage a season all matter.
Why spaying is recommended at all
Two reasons carry most of the weight.
Pyometra. A life-threatening infection of the uterus, common in unspayed older bitches, requiring emergency surgery that costs several times a routine spay and carries real mortality. Spaying prevents it outright.
Mammary tumours. Risk rises with each season before spaying. In dogs roughly half of mammary tumours are malignant; in cats the figure is far higher. Spaying early is strongly protective.
Set against these: the orthopaedic and cancer associations in large breeds noted above, and a modest increase in urinary incontinence in some spayed bitches, which is usually treatable with medication.
"Should she have one litter first?"
No. This is folklore, and the evidence runs against it. There is no health or behavioural benefit to a litter, and each season before spaying increases mammary tumour risk.
Ovariectomy or ovariohysterectomy?
Some practices remove only the ovaries; others remove the ovaries and the uterus. Both are standard and outcomes are equivalent. Ovariectomy is the norm across much of Europe and is often done laparoscopically. If you are told only the ovaries are coming out, nothing is being skipped.
Recovery
Most animals are back to themselves within a couple of days and want to do more than they should.
- Home the same day in most cases
- A cone or surgical suit for 10 to 14 days — the single most important thing you control, since licking is what causes wound breakdown
- Lead walks only, no running or jumping, for two weeks
- Sutures out at 10 to 14 days, or dissolvable ones needing no visit
- A quiet, slightly subdued day or two is normal
Call your vet for a red, swollen or discharging incision, repeated vomiting, refusal to eat beyond the first day, or a wound that opens.
Weight afterwards
Metabolic rate falls after spaying, so the same food becomes too much food. Weight gain is a feeding problem, not an inevitability — reduce the portion by around 20% and watch the waistline. This is entirely within your control and worth getting right, because obesity drives far more disease than the surgery ever will.
Who isn't a candidate
- Pregnancy: Pregnancy does not prevent the surgery but changes it — the uterus is larger and more vascular, cost and risk rise, and the pregnancy is ended. Discuss timing openly rather than concealing a suspected pregnancy.
- Age: Very young puppies and kittens below the weight or age threshold a practice uses; most set a minimum, and paediatric protocols differ from adult ones.
- Concurrent condition: Uncontrolled illness, active infection, significant anaemia or untreated heart disease — an elective procedure waits until the patient is stable.
- Other: A season in progress or just finished. Many practices delay two to three months after a heat because the tissue is engorged and bleeds more readily.
- Breed: In large and giant breeds, timing is genuinely debated — early spaying is associated with a higher rate of some orthopaedic and cancer outcomes. This is a conversation about *when*, not *whether*.
Common questions
How much does it cost to spay a dog?
Roughly $250 to $1,200. The spread reflects what is included — pre-anaesthetic bloodwork, IV fluids, a dedicated monitoring nurse, multimodal pain relief, the cone and the recheck — rather than a different operation. Larger dogs cost more than small ones, and laparoscopic spays carry a premium. Ask for an itemised quote.
What is the best age to spay a dog?
For cats and small dogs, the traditional timing before or around the first season remains well supported. For large and giant breeds the advice has changed: several studies link early spaying to higher rates of cruciate rupture, hip dysplasia and some cancers, so many vets now recommend waiting closer to skeletal maturity at 12 to 24 months. Discuss your specific dog.
How long does it take a dog to recover from being spayed?
Most dogs are bright within a day or two and back to normal activity at two weeks. The critical part is preventing licking with a cone or surgical suit for 10 to 14 days and restricting exercise to lead walks. Sutures come out at 10 to 14 days unless dissolvable ones were used.
Should I let my dog have one litter before spaying?
No. There is no health or behavioural benefit, and each season before spaying increases the risk of mammary tumours — roughly half of which are malignant in dogs. The "one litter first" idea is folklore rather than veterinary advice.
What are the risks of spaying a dog?
The main ones are anaesthetic risk, bleeding, and wound infection or breakdown, all uncommon in healthy animals. Longer term, some spayed bitches develop urinary incontinence, usually treatable with medication, and in large breeds early spaying is associated with higher rates of certain orthopaedic problems and cancers. Set against this, spaying prevents pyometra outright.
