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

At a full-service clinic, expect $300 to $700 for most dogs, depending on size and sex. Spaying a female is generally more expensive than neutering a male because it is a more involved abdominal surgery. Low-cost clinics and nonprofit programs bring that down significantly -- sometimes to $100 to $250.

How much does it cost to spay or neuter a cat in Denver?

Cat spay or neuter costs range from $150 to $350 at a full-service clinic. Low-cost and nonprofit clinics often charge $50 to $150 for cats, and some programs specifically targeting community cats charge even less.

What does the cost include?

At a full-service clinic, the quoted price typically includes the procedure, general anesthesia, basic monitoring, and pain medication to go home. Some clinics include pre-surgical bloodwork in the price; others offer it as an add-on. Post-operative pain medication, e-collars, and follow-up exams may be billed separately -- ask specifically what is included when you get a quote.

What is the best age to spay or neuter?

Traditional recommendations are 6 months for cats and most dogs. For large and giant breed dogs, some vets recommend waiting until 12 to 18 months because early spay/neuter can affect bone development and joint health. This is a conversation worth having with your vet based on your specific dog's breed.

Spay and neuter costs in the Denver area: what to budget

By Maya Krishnan · Updated 2026-05-03

Cost ranges in this guide are based on owner-reported data and general market rates in the Denver metro area. Confirm pricing with your specific clinic before scheduling. This is not medical advice.

What changes the price

Spay and neuter procedures vary in cost based on several concrete factors. Understanding them helps you compare quotes without wondering why one clinic is twice the price of another.

Sex and procedure type. Spaying a female (ovariohysterectomy or ovariectomy) is abdominal surgery with more steps than neutering a male. The time, complexity, and risk are higher, which is reflected in the price. A female is always more expensive than a male of the same size.

Pet size. Larger dogs require more anesthesia (dosed by weight), larger suture material, longer procedure time, and more post-op pain medication. A 10-pound dog costs meaningfully less than a 90-pound dog.

Clinic type. A full-service animal hospital with advanced monitoring equipment and boarding staff charges more than a low-cost spay/neuter clinic that does high-volume routine procedures with efficient protocols. Both can produce good outcomes — they serve different needs.

Pre-surgical bloodwork. Many vets recommend or require a pre-anesthetic blood panel, especially for pets over a certain age or with any health history. This adds $60 to $120 to the cost but provides important safety information.

Cost comparison by clinic type and pet

Pet type / procedure	Low-cost clinic	Full-service clinic
Cat neuter	$50 - $100	$150 - $250
Cat spay	$75 - $150	$200 - $350
Small dog neuter (under 30 lb)	$100 - $175	$250 - $400
Small dog spay (under 30 lb)	$125 - $200	$300 - $500
Large dog neuter (30 lb+)	$150 - $250	$350 - $550
Large dog spay (30 lb+)	$175 - $300	$450 - $700

Low-cost ranges reflect nonprofit clinics and high-volume spay/neuter programs. Individual quotes will vary.

What low-cost clinics typically offer

Low-cost spay/neuter programs focus on doing one procedure well at volume. What they typically include:

The surgical procedure
General anesthesia
Basic vital monitoring
Post-op pain injection
An e-collar or post-op instructions

What they may not offer:

Pre-anesthetic bloodwork (may be optional)
IV fluids during surgery (some include, some do not)
Overnight boarding if the pet needs observation
Suture removal follow-up appointments at the same clinic

This is not a knock against low-cost clinics — for a young, healthy pet with no prior health issues, the risk profile is different from an older or compromised animal. Ask what is and isn’t included so you can compare fairly.

Timing and recovery

Most pets go home the same day. Recovery time is typically:

Cats and small dogs: 5 to 7 days of restricted activity; sutures dissolve or are removed at 10 to 14 days
Large dogs: 10 to 14 days of restricted activity; no running, jumping, or stairs during healing

The e-collar (cone) is not optional if your pet licks or chews at the incision. Licking introduces bacteria and can disrupt healing.
