Spaying (ovariohysterectomy) is a surgical procedure to remove a female dog's reproductive organs — the ovaries and uterus. It is one of the most common veterinary surgeries performed in the United States, with over 80% of female dogs spayed before age 2.
The national average cost to spay a dog is $455, with most owners paying between $250 and $2,000. The price depends on your dog's weight, your location, and the type of clinic you choose.
How Much Does It Cost to Spay a Dog?

Low-Cost Dog Spay Options
If the price at a private veterinary hospital is too high, you have several options:
- •Low-cost spay/neuter clinics: These nonprofit or subsidized clinics charge $50–$200 and are available in most U.S. cities. Find a clinic near you.
- •Humane societies and ASPCA chapters: Many offer low-cost or free spay surgery for low-income pet owners.
- •Mobile clinics: Some cities have mobile spay/neuter vans that rotate through neighborhoods.
- •Veterinary teaching hospitals: Teaching hospitals at veterinary schools often offer lower prices because procedures are performed by supervised students.
- •Financial assistance programs: Organizations like Brown Dog Foundation, Magic Bullet Fund, and RedRover offer grants for veterinary care.
Dog Spay Surgery Recovery
Recovery from spay surgery typically takes 10 to 14 days. Key recovery milestones:
- •Day 1–2: Your dog will be groggy. Keep her calm, warm, and away from other pets. Offer small amounts of water and food.
- •Day 3–5: Energy should start to return. Limit activity — no running, jumping, or stairs.
- •Day 7–10: Incision should be healing well. Check for redness, swelling, or discharge daily.
- •Day 10–14: Sutures are typically removed (if non-dissolvable). Most dogs are fully recovered.
Warning signs to call your vet: Excessive swelling, foul-smelling discharge, refusal to eat or drink, vomiting lasting more than 24 hours, or your dog licking/biting the incision.
Frequently Asked Questions
How much does it cost to spay a dog at a low-cost clinic?
Low-cost spay clinics typically charge $50 to $200 for a dog spay, compared to $300 to $2,000 at private veterinary hospitals. These clinics are often run by humane societies, ASPCA chapters, or nonprofit organizations.
Is spay surgery more expensive for larger dogs?
Yes. Larger dogs require more anesthesia, longer surgery time, and larger surgical materials. A small dog spay (under 25 lbs) may cost $250, while a large breed (90+ lbs) can cost $1,000 or more at a private hospital.
How long does dog spay surgery take?
The procedure typically takes 30 to 90 minutes, depending on the dog's size and whether she's in heat or pregnant. The dog is usually dropped off in the morning and picked up the same afternoon.
Does pet insurance cover spay surgery?
Most pet insurance policies do not cover elective spay surgery as it's considered a routine/preventive procedure. However, some wellness plans or add-on riders do include it. Check with your insurance provider.
At what age should I spay my dog?
Most veterinarians recommend spaying between 6 and 12 months of age. For large breeds, some vets recommend waiting until 12–18 months to allow full skeletal development. Discuss timing with your vet.
What happens if I don't spay my dog?
Unspayed female dogs have a higher risk of mammary tumors, pyometra (life-threatening uterine infection), and unwanted pregnancies. Spaying before the first heat cycle reduces mammary cancer risk by 99.5%.
How much does it cost to spay a dog in heat?
Spaying a dog in heat costs 25–50% more than a standard spay, typically $350–$2,500. During heat, blood vessels are engorged and tissues are more fragile, making the surgery more complex and time-consuming. Many vets recommend waiting until the heat cycle ends if possible.
How much does it cost to spay a pregnant dog?
Spaying a pregnant dog costs $400–$2,500+, roughly 50–75% more than a standard spay. The procedure is more complex due to increased blood flow and larger uterus size. Some vets will not perform the surgery for ethical reasons late in pregnancy.
Can I spay my dog at any age?
Yes, dogs can be spayed at any age, but most vets recommend 6–12 months. Spaying older dogs (7+ years) may require pre-surgical blood work and additional monitoring, adding $100–$300 to the cost. Senior dog spays carry slightly higher anesthesia risks.
How much is a dog spay at PetSmart or Petco?
PetSmart and Petco host low-cost vaccination clinics but typically do not perform spay surgery in-store. However, they partner with local low-cost spay/neuter providers. Check with your local store for partner clinic referrals — prices are usually $50–$200.
What's the difference between a spay and an ovariohysterectomy?
There is no difference. Spay is the common term for an ovariohysterectomy — the surgical removal of the ovaries and uterus. Some vets offer an ovariectomy (removal of ovaries only), which is less invasive but not commonly performed in the U.S.
Will spaying change my dog's personality?
Spaying typically reduces hormone-driven behaviors like roaming, mounting, and irritability during heat cycles. Your dog's core personality will not change. Some dogs may be slightly less active after spaying due to metabolic changes — monitor food intake to prevent weight gain.
