If you are looking for a dog CBC values chart that you can print and keep with your dog’s medical records, this guide is designed for clarity and simplicity. When reviewing bloodwork, it helps to see normal ranges in one organized place without excess explanation scattered throughout the page.
A Complete Blood Count evaluates red blood cells, white blood cells, and platelets. These numbers reflect oxygen delivery, immune system activity, and clotting function. While reference intervals vary slightly by laboratory, the ranges below represent typical adult canine values.
Quick answer: reference ranges are guidelines, not diagnoses. Slight variations are common and often temporary — always compare your dog’s results to the specific range listed on their own lab report, since labs can differ slightly.
Dog CBC Values Chart
Red Blood Cells (Oxygen Delivery)
| Test | Typical Normal Range | What It Reflects |
|---|---|---|
| RBC | 5.5–8.5 million/µL | Number of red blood cells |
| Hematocrit (HCT / PCV) | 37–55% | Percentage of blood made up of red cells |
| Hemoglobin (HGB) | 12–18 g/dL | Oxygen-carrying protein level |
| Reticulocytes | Lab dependent | Bone marrow response to anemia |
Red blood cells carry oxygen throughout the body. Low values suggest anemia. High values most commonly reflect dehydration.
White Blood Cells (Immune System)
| Test | Typical Normal Range | What It Reflects |
|---|---|---|
| Total WBC | 6,000–17,000/µL | Total immune cell count |
| Neutrophils | 3,000–11,500/µL | Bacterial defense |
| Lymphocytes | 1,000–4,800/µL | Immune regulation |
| Monocytes | 150–1,350/µL | Chronic inflammation |
| Eosinophils | 100–1,250/µL | Allergies and parasites |
| Basophils | 0–100/µL | Rare inflammatory response |
White blood cells increase with inflammation, infection, stress, or immune stimulation. Low counts can increase infection risk if significant.
Platelets (Clotting Function)
| Test | Typical Normal Range | What It Reflects |
|---|---|---|
| Platelet Count (PLT) | 200,000–500,000/µL | Clotting ability |
Low platelets may increase bleeding risk. Mild decreases without symptoms are often monitored.
Quick Interpretation Notes
High Red Blood Cells
High red blood cells in dogs most commonly reflect dehydration rather than true disease. When a dog loses fluid through vomiting, diarrhea, decreased water intake, or excessive panting, the liquid portion of the blood decreases. The red cells remain, but they become more concentrated, which raises the hematocrit and RBC count on a CBC.
This is called relative polycythemia and typically corrects once hydration is restored. If red blood cell levels remain elevated after proper fluid correction, your veterinarian may investigate less common causes such as chronic low oxygen levels from heart or lung disease, or rarely, bone marrow overproduction. Dehydration is the most common cause. Repeat testing after fluids often clarifies the situation. Persistent elevation requires further evaluation but is uncommon.
Low Red Blood Cells
Low red blood cells indicate anemia, meaning there are fewer oxygen-carrying cells circulating in the bloodstream. Anemia can result from blood loss, destruction of red cells, or decreased production in the bone marrow. The severity of anemia helps determine urgency. Mild anemia may cause no visible symptoms, while more significant cases can lead to pale gums, weakness, or fatigue. A key part of evaluation is assessing reticulocytes, which indicate whether the bone marrow is responding appropriately. Anemia is a finding, not a diagnosis. Severity and clinical signs guide urgency. Bone marrow response helps determine the cause.
High White Blood Cells
High white blood cells often signal inflammation, infection, stress, or immune stimulation. The total WBC count is helpful, but the specific type of white cell that is elevated provides more diagnostic information. Neutrophils often increase with bacterial infection or stress. Eosinophils may rise with allergies or parasites. Mild elevations are common and frequently temporary. Inflammation is a common cause. The differential count provides important clues. Mild increases are often monitored.
Low White Blood Cells
Low white blood cells can increase infection risk when significantly decreased, especially if neutrophils are low. Causes may include viral infections, bone marrow suppression, immune-mediated conditions, or medication effects. Mild decreases without symptoms are often monitored with repeat testing. Severity determines infection risk. Trends over time provide clarity. Follow-up testing is commonly recommended.
Low Platelets
Low platelets, or thrombocytopenia, may increase bruising or bleeding risk depending on how low the count falls. Mild reductions may cause no symptoms, while more severe decreases can lead to nosebleeds, gum bleeding, or small red spots on the skin. Causes include immune-mediated destruction, tick-borne disease, inflammation, or bone marrow disorders. Bleeding risk depends on the platelet count. Many causes are treatable once identified. Prompt evaluation improves safety and outcomes.
- Numbers must be interpreted alongside symptoms
- Trends over time are more informative than one result
- Always review abnormal findings with your veterinarian
