Veterinarians test for leukemia using blood tests to check for high white blood cell counts, anemia, or low platelets, often starting with a Complete Blood Count (CBC) and blood smear. For cats, a quick in-house ELISA test detects the FeLV virus, while advanced diagnostics for dogs include flow cytometry, PCR tests, and bone marrow aspirates.

Early signs of canine leukemia are often subtle and non-specific, including lethargy, poor appetite, weight loss, and increased thirst/urination, with some dogs showing no symptoms until a routine blood test reveals a high white blood cell count (WBC) or enlarged lymph nodes/spleen appear. Because these signs mimic other conditions, a vet visit for a CBC (Complete Blood Count) is crucial for diagnosis, as leukemia involves uncontrolled growth of abnormal white blood cells.
 

What can be mistaken for leukemia in dogs?

Leukemia can have similar physical exam and blood work findings as other diseases, including lymphoma and the tick-borne disease Ehrlichia. This means leukemia is sometimes misdiagnosed at first.

What tests can confirm leukemia?

Can you cure leukemia in dogs?

Although complete remissions are rare, survival times vary among 1 to 3 years with a good quality of life. AMLs present a poor response to therapy and due to scarce information on the literature regarding the response of the subtypes of AML, there is no consensus on the protocol to treat these conditions.

How long can a dog live with untreated leukemia?

The average age a dog is diagnosed with ALL is 6 years old, and without treatment, their life expectancy can be as short as a few days. With treatment, many can respond but sadly the response and survival time on average is less than two months.

What age is leukemia usually diagnosed?

Leukemia diagnosis varies by type, but it's often seen in older adults (median age 67 overall, around 70 for CLL/AML) and is also the most common cancer in children, especially between ages 2 and 5 for acute lymphocytic leukemia (ALL). The risk increases with age, with many cases diagnosed in people 65 and older, though different types peak at different ages (e.g., CML around 65, ALL in kids). 

Do they do a PET scan for leukemia?

PET/CT scans are used occasionally for CLL. The procedure combines the pictures from a positron emission tomography (PET) scan and a computed tomography (CT) scan. The pictures from both scans are combined to create a more detailed picture than either test would produce by itself.

What causes a dog to get acute leukemia?

Acute Myeloid Leukemia is a Myeloproliferative disease (MPD), which are a group of neoplastic ailments originating in the bone marrow. MPDs result from an unregulated growth of hematopoietic stem cells (multipotent stem cells that give rise to all types of blood cells).
