Complete Blood Count (CBC) for Dogs and Cats

A complete blood count examines red blood cells, white blood cells and platelets.

Overview and the key decision

A complete blood count examines red blood cells, white blood cells and platelets. It helps investigate illness and assess a pet before some procedures, but it does not identify every cause of illness or replace a physical examination.

This guide explains decisions to discuss with your veterinarian. The right plan depends on your pet’s current condition, examination and medical history.

What this guide cannot determine

An online guide cannot establish your pet’s diagnosis, choose a test or procedure, or replace an examination. The information below does not provide a medication or home procedure protocol.

What the assessment or procedure involves

A small blood sample is collected into an appropriate tube. An analyser measures cell numbers and related values; a blood smear may add information about cell appearance or confirm a result that needs closer review.

What the findings can tell us

Low red-cell measurements indicate anaemia, but the next question is why: blood loss, cell destruction and reduced production require different investigations. White-cell changes can reflect inflammation, stress or other disorders. Platelet findings must be interpreted with sample quality and any clumping in mind.

Important limits of the findings

A normal CBC does not exclude an intestinal blockage, early organ disease or every infection. A high white-cell count does not, on its own, prove a bacterial infection or establish a need for antibiotics.

Preparation and useful records

Tell the team about bleeding, medications, recent illness and earlier results. Ask whether fasting is needed for the particular tests being collected; do not delay an urgent assessment to obtain a fasted sample.

When to call urgently

Pale or grey gums with weakness, collapse, breathing difficulty or significant bleeding require immediate assessment rather than waiting for a routine blood-test appointment.

If SKVH cannot receive your pet promptly or the clinic is closed, contact an open emergency hospital. Do not wait for a routine message response when urgent signs are present.

How the care plan is chosen

The veterinarian combines the blood count with the examination. A reticulocyte count, chemistry panel, urine testing, imaging or selected further tests may be recommended to answer the question the CBC raises.

Risks and alternatives to discuss

Collection can cause brief discomfort or a small bruise. Difficult sampling, a clot in the tube or other sample problems can mean a new sample is needed. The team considers bleeding risk when deciding how to collect blood.

Follow-up and unanswered questions

Ask which findings change today's plan and which need monitoring. If the pet remains unwell, an apparently reassuring count should not end the investigation automatically.

Care at SKVH and next steps

SKVH combines appointment-based urgent assessment during clinic hours with wellness, diagnostics, surgery, dentistry and ongoing care for dogs and cats in Stittsville, Kanata and West Ottawa. One-off urgent visits and continuing care are both welcome.

Findings, medically appropriate options and an individual estimate are discussed before proceeding. Test and procedure availability, monitoring needs and referral are considered for the individual case; this guide does not promise every test or treatment is available in-house.
