The Most Expensive Dog and Cat Surgeries, Ranked From Real Vet Bills

We ranked surgeries by what owners actually paid, using real vet bills in our data. For dogs, fracture repair surgery has the highest typical bill: most fall between $2,300 and $4,000. In vet quotes, TPLO surgery comes out on top, with most quotes between $4,500 and $7,750. For cats, urinary blockage treatment or surgery carries the highest quotes, most between $2,900 and $6,500. A surgery is ranked only when we have at least 8 bills for that species.

Why vet quotes run higher than paid bills

A quote usually covers the whole planned stay and often lists the top of the vet's range. Paid bills can be split — a deposit and a final invoice, or one invoice per day in the hospital — so one paid invoice is sometimes only part of the full cost.

What makes a surgery bill this big

The surgery fee is often the smaller part of the total. Nights in the hospital, a specialist or emergency hospital, imaging like X-rays, CT or MRI, implants such as plates and screws, and after-hours fees are what push a bill into the thousands.

How we built this ranking

Every number comes from real vet bills in our data, with personal details removed. Each bill is counted once, under its main surgery, using the full bill total. Paid bills and vet quotes are kept separate. A surgery is ranked only when we have at least 8 bills for that species, and prices are shown as rounded ranges. Test uploads and non-US bills are left out. Updated October 2026.

Frequently asked questions

What is the most expensive dog surgery?

In our data, fracture repair surgery has the highest typical paid bill, with most bills between $2,300 and $4,000. In vet quotes, TPLO surgery is the most expensive: most quotes fall between $4,500 and $7,750. The largest single dog surgery bill we have seen was over $20,000, for spinal stabilization surgery.

What is the most expensive cat surgery?

Urinary blockage treatment or surgery has the highest vet quotes in our data, with most between $2,900 and $6,500. Among bills owners actually paid, dental extractions (oral surgery) has the highest typical bill, most between $800 and $2,200. Some of the largest cat bills we have seen were abdominal and foreign body surgeries, but we have fewer than 8 of those, so they are not ranked yet.

Why are vet quotes higher than the bills people paid?

A quote usually covers the whole planned stay and often lists the top of the vet's range. Paid bills can be split, for example a deposit followed by a final invoice, or one invoice per day in the hospital. So a single paid invoice is sometimes only part of the full cost.

Why does the same surgery cost so much more at one hospital than another?

The biggest swings come from where the surgery happens and what comes with it. Specialist and emergency hospitals charge more than general practices. Each night in the hospital, each scan and each implant adds to the bill. Prices also vary by city and state.

How do spay and neuter costs compare?

They are far cheaper. In our data, most dog spay bills fall between $400 and $1,000 and most dog neuter bills between $300 and $850. For cats, most spay bills are $175 to $450 and most neuter bills $250 to $950.

Why isn't TPLO or spinal surgery in the paid-bill ranking?

We rank a surgery only when we have at least 8 paid bills for it, per species, so one unusual bill cannot move the list. TPLO and spinal surgery do not have 8 paid bills yet. TPLO does have enough vet quotes, so it appears in the quotes table.

How is this ranking built?

From real vet bills uploaded to Vet Receipt, with personal details removed. Each bill is counted once, under its main surgery, and we use the full bill total. Test uploads and non-US bills are left out. Paid bills and vet quotes are kept in separate tables.
