Diagnosis $500-$1,500, surgery $2,000-$5,000, chemotherapy $3,000-$5,000. This aggressive cancer develops silently in the spleen, heart, or liver. By symptom onset, it has spread. Most dogs present as emergencies - ruptured tumor causing internal bleeding and collapse.
HSA is aggressive cancer of blood vessel lining cells. It forms blood-filled tumors that rupture without warning, causing life-threatening internal bleeding. Spleen most common (~50%), then heart and liver. Spreads rapidly. Aggressive, often fatal within months
Sudden collapse or weakness - often first sign. Pale gums from internal bleeding. Distended abdomen. Rapid breathing and heart rate. Lethargy and loss of appetite. Intermittent weakness that resolves then recurs. Sudden emergency with no prior warning
Bloodwork ($200-$400), abdominal ultrasound ($300-$500), chest X-rays ($150-$300). Echocardiogram ($300-$600) if cardiac HSA suspected. Surgical biopsy needed for confirmation. $500-$1,500
Stabilization with fluids and transfusions ($1,000-$2,000). Splenectomy ($2,000-$5,000). Doxorubicin chemotherapy, 5-6 treatments ($3,000-$5,000). Surgery alone: 1-3 months median. Surgery plus chemo: 4-6 months. $5,000-$10,000 total
Emergency visit, surgery, chemotherapy, and follow-up imaging. Often compressed into just a few months. $5,000-$12,000 is typical for full treatment.
Golden Retrievers, German Shepherds, Labrador Retrievers, and Flat-Coated Retrievers have the highest rates. Large breeds over 6 years old are most commonly affected.
Without treatment: days to weeks. Surgery alone: 1-3 months. Surgery plus chemo: 4-6 months median. Less than 10% of dogs survive one year even with aggressive treatment.
No proven prevention exists. Annual abdominal ultrasounds for at-risk breeds over age 6 may catch tumors before rupture. Early detection screening is gaining traction but remains unproven.

Emergency visit, surgery, chemotherapy, and follow-up imaging.
Most policies cover cancer diagnosis, surgery, and chemotherapy. HSA is not a hereditary exclusion. Confirm your policy has no cancer-specific exclusions or sublimits capping payouts below the $5,000-$12,000 typical cost.
Most HSA cases present as emergencies - sudden collapse, internal bleeding. If uninsured, you face a $5,000-$10,000 decision in the ER with no time to enroll. Insurance must be in place before crisis. For at-risk breeds, this justifies the premium.
Stabilization ($1K-$2K), surgery ($2K-$5K), chemotherapy ($3K-$5K) all within weeks. $5,000-$12,000 hits in 2-3 months. Without insurance, many owners choose euthanasia over treatment due to cost.
With costs reaching $12,000 fast, low annual limits may run out mid-treatment. Choose at least $15K-$20K annual coverage or unlimited. Check if deductible resets annually - matters for treatments spanning policy years.

My mother-in-law took her German boxer to the veterinary emergency room - $1,200 in tests, no answers. A different vet solved it in minutes with $8 pills.
That moment stuck with me. When you're scared, you'll pay anything - and some vets price accordingly. I dug into vet costs and insurance. Confusing policies, buried exclusions, impossible to compare. So I built the resource I wish existed: real costs, real exclusions, plain language. Not here to sell you a policy. Here so you don't get blindsided.
