Dog Splenectomy Cost in 2026: $1,700 to $5,000

A dog splenectomy costs $1,700 to $5,000 in the United States, and $2,300 is the typical price. Regionally the typical price runs from $2,000 in North Carolina to $4,500 in Northampton, Massachusetts — a 2.3x spread for the same procedure.

The surgery is the small number; the biopsy decides the real one

Seven US practices publish a canine splenectomy price and they cluster between $1,700 and $2,500. That is the operation.

What it costs to have had it done depends entirely on what the pathologist finds. ACVS reports that up to two-thirds of dogs with splenic masses have a cancerous mass, and that most of those are hemangiosarcoma.

The two outcomes are not two prices, they are two different diseases. ACVS states that benign splenic masses are effectively cured by surgery. For hemangiosarcoma, survival with surgery alone is two to three months or less, with one-year survival under 10%, and chemotherapy may extend that to six to eight months.

So the honest budget is $2,300 for the surgery and then either nothing or a full chemotherapy course. Veterinary Surgical Solutions includes histopathology in its price, which is worth checking on any quote — that report is what tells you which of the two situations you are in.

Seven published prices, and not one of them is the 2am price

The published spread is 2.9x: $1,700 at Affordable Animal Surgery in Las Vegas to $5,000 at Integrity Veterinary Center, a 24-hour emergency and specialty hospital in Massachusetts.

Between them: Veterinary Surgical Solutions $1,744 to $2,491 by weight, Affordable Veterinary Surgery at a flat $2,000, Access Veterinary Care at $2,300, Animal Works at $2,500 and Warm Springs Pet Hospital at $4,400.

Every one of those is a scheduled price. A dog whose splenic mass has ruptured is bleeding into its abdomen, and no fee sheet in the US prices that night.

Two practices come close by saying what they exclude. Integrity Veterinary Center qualifies its $4,000 to $5,000 figure with the words "stable patient". Affordable Animal Surgery states that blood transfusion is not available during its clinic hours, and that overnight hospitalisation and any after-hours transfusion are not included in its price.

Animal Works publishes the surcharges outright rather than folding them in: emergency consult $135, emergency staffing fees $200 to $1,200, overnight $250, weekend hospitalisation $250 to $350. Those are the same published lines we use on the dog bowel obstruction surgery page, because they are charged the same way for any abdominal emergency.

Body weight is the only variable every price sheet bands on

Veterinary Surgical Solutions charges $1,744 to $2,004 under 30 lbs, $1,956 to $2,230 at 31 to 60 lbs and $2,222 to $2,491 over 60 lbs, histopathology included.

That is a 43% span for removing the same organ, and it is not arbitrary — a bigger dog takes more anaesthetic drug, more surgical time and more materials.

It also lands badly. The breeds most affected by splenic masses are the large, deep-chested ones, and they sit in the top band by definition.

Nothing else on the published sheets bands this operation. No practice prices it by whether the mass is benign, because nobody knows that before the surgery.

What a splenectomy quote does not include

Three lines routinely arrive separately, and none of them is in the surgical fee at most practices.

Staging before the operation. Affordable Veterinary Surgery states that a chest x-ray and abdominal ultrasound may be recommended beforehand to look for spread. CareCredit's national averages are $213 for a dog x-ray and $483 for an abdominal ultrasound, and neither is included in any splenectomy quote we read.

Histopathology on the removed spleen. Included in the fee at Veterinary Surgical Solutions, billed separately elsewhere, and not priced on any sheet we found — our $150 to $400 line is an estimate.

Nights in hospital. $619 per night at a veterinary clinic and $866 at an emergency clinic on CareCredit's national averages. A dog transfused overnight before surgery pays for the night and the transfusion before the surgeon starts.

The clotting profile is worth asking about too. Veterinary Surgical Solutions publishes pre-anaesthetic bloodwork at $122.50 to $132.50; CareCredit's national averages are $104 for a CBC and $164 for a chemistry panel. On a bleeding dog these are not optional paperwork, they are what decides whether anaesthesia is safe yet.

Where a splenectomy legitimately costs less

At a daytime surgical practice, and the saving is real as long as the dog is stable enough to use one.

The cheap end of this market is not a lower standard, it is a narrower service. Affordable Animal Surgery's $1,700 to $2,500 excludes overnight hospitalisation and after-hours transfusion and says so on the page. Veterinary Surgical Solutions charges $65 for the consult that gates the booking, and includes histopathology in the surgical fee.

The expensive end buys availability. A 24-hour hospital is staffed to take a dog that is bleeding at midnight, and it charges every patient for that whether they needed it that night or not.

So the question that moves this bill is clinical, not financial: is this a mass found on a routine scan, or a dog bleeding now? The first can be scheduled. The second cannot.

Is a splenectomy worth doing if the mass turns out to be cancer?

The decision has to be made before anyone can answer that, which is the hard part of this page.

The mass is found on ultrasound, and imaging cannot reliably tell a benign haematoma from a hemangiosarcoma. The spleen has to come out and go to a pathologist for the question to be answered at all.

What ACVS publishes is the prior: up to two-thirds of splenic masses in dogs are cancerous, and most of those are the aggressive tumour. That leaves a meaningful minority of dogs for whom this $2,300 operation is a cure.

For the majority it buys time and stops the bleeding. Whether the chemotherapy that follows is worth its own price is a separate decision, made with a diagnosis in hand instead of a probability.

Will pet insurance cover a splenic mass in an older dog?

Usually yes on the surgery, and the constraint is the annual limit rather than the wording.

A splenectomy is an illness or accident claim and is covered by accident-and-illness policies once the waiting period has passed, provided nothing about the mass was on record before enrolment.

Two things decide these claims in practice. The mass is usually found suddenly in an older dog, and older dogs are the ones most likely to have been enrolled recently or never — several carriers cap or refuse new enrolments above a maximum age.

And if the biopsy comes back hemangiosarcoma, the expensive part is what follows. A surgery under $2,500 plus a chemotherapy protocol can exhaust a $5,000 annual cap inside one policy year.

The number we could not find

The blood transfusion line on this page is estimated, and it is the weakest figure we publish for this procedure. No practice we checked prices a transfusion; Affordable Animal Surgery states only that it is not available in clinic hours and is not included.

CareCredit publishes no splenectomy figure at all and there is no 50-state survey for this operation, so the four census-region rows are indexed from the national range using the geographic ratio measured across CareCredit's 2025 procedure tables. They are estimates, and the practice-to-practice spread is far larger than any regional effect.

The top of this range is therefore a stable-patient specialty price, not a worst case. If your dog's spleen comes out during bloat surgery instead, that is priced on the dog gastropexy page, where ACVS notes a splenectomy is performed during a GDV if the blood supply is compromised. For soft-tissue masses elsewhere on the body, see dog tumour removal. The rest of our pricing work is on the vet cost index.

These are the prices behind the range at the top of the page, one row per geography we could source. The basis column says how each row was arrived at.

What changes the price

Two invoices for the same procedure diverge for a small number of reasons. These are the ones that move the total most.

Body weight

The only variable every published price sheet bands on. Veterinary Surgical Solutions charges $1,744-$2,004 under 30 lbs, $1,956-$2,230 at 31-60 lbs and $2,222-$2,491 over 60 lbs - a 43% span for the same organ, and the large deep-chested breeds most affected sit in the top band

Whether it is bleeding when you arrive

Two hospitals put this in writing rather than leaving it implied. Integrity Veterinary Center qualifies its $4,000-$5,000 splenectomy price 'stable patient'. Affordable Animal Surgery states that blood transfusion is not available during its clinic hours and that overnight hospitalisation and after-hours transfusion are not included in its $1,700-$2,500 price. Animal Works publishes the surcharges outright: emergency consult $135, emergency staffing fees $200-$1,200, overnight $250, weekend hospitalisation $250-$350

Staging before surgery

Affordable Veterinary Surgery states a chest x-ray and/or abdominal ultrasound may be recommended before surgery to look for spread. CareCredit national averages: $213 for a dog X-ray and $483 for an abdominal ultrasound, neither included in any splenectomy quote

Histopathology - included at some practices, not others

Veterinary Surgical Solutions includes histopathology in its price. It is not optional: ACVS reports that up to two-thirds of dogs with splenic masses have a cancerous mass, and the biopsy is what separates a cure from a two-month prognosis

What the biopsy says

The largest cost in this condition is not surgical. ACVS: benign splenic masses are effectively cured by surgery, but survival with surgery alone for hemangiosarcoma is two to three months or less, with one-year survival under 10%, and chemotherapy may extend that to six to eight months - a whole additional treatment course

Nights in hospital

Does pet insurance cover dog splenectomy?

Dog Splenectomy is normally covered by a standard accident-and-illness policy. A splenectomy is an illness or accident claim and is covered by accident-and-illness policies once the waiting period has passed, provided nothing about the mass was on record before enrolment. Two things decide these claims. First, the mass is usually found suddenly in an older dog, and older dogs are the ones most likely to have been enrolled recently or not at all - several carriers cap or refuse new enrolments above a maximum age. Second, if the biopsy comes back hemangiosarcoma, the expensive part is the chemotherapy that follows, and that is where annual limits bite: the surgery is under $2,500 but a chemotherapy protocol on top can exhaust a $5,000 annual cap.

What you would get back: 70-90% of the covered bill after the annual deductible, subject to the annual limit, which a subsequent chemotherapy protocol can exhaust.

Coverage rules differ enough between carriers that the only useful answer is a side-by-side: our pet insurance comparison for dog splenectomy shows which policies pay for it, what the waiting period is, and what counts as pre-existing.
