Leukemia

Leukemia is a type of cancer that affects the white blood cells, which are part of the immune system. When your dog has leukemia, his or her body will produce too many immature white blood cells, instead of the normal amount.

The symptoms of leukemia in dogs can include:

• Swelling in the lymph nodes (the small glands found throughout the body)
• Weight loss
• Fever
• Anemia (reduced red blood cells)

Leukemia can be difficult to diagnose because it’s rare and has no specific symptoms. Your vet will conduct a physical exam and check for signs like swollen lymph nodes or anemia before making a diagnosis. A biopsy of the spleen may also be performed if necessary.
