How to take blood from dogs on an empty stomach? - in detail

Taking blood from dogs on an empty stomach is a common procedure in veterinary medicine, often necessary for diagnostic purposes. Here's a step-by-step guide to ensure the process is as smooth and stress-free as possible:

  1. Preparation:

    • Ensure that the dog has not eaten for at least 8 hours before the blood draw. This helps prevent lipemia, which can interfere with test results.
    • Hydrate the dog adequately by providing water up to two hours before the procedure.

  2. Selection of Sampling Site:

    • Common sites for venipuncture include the jugular vein, cephalic vein, and medial saphenous vein. The jugular vein is typically the easiest and most accessible site for blood collection.

  3. Gathering Equipment:

    • Collect necessary materials: a sharp, clean needle (21-25 gauge), syringe appropriate to the size of the dog, gauze pads, alcohol swabs, adhesive bandages, and a tube or vial for blood collection.

  4. Restraint and Comfort:

    • Position the dog comfortably on a non-slip surface. You may need an assistant to help restrain the dog gently but firmly during the procedure.
    • Calm the dog with soft words and gentle strokes. This helps reduce stress and makes the process easier for both you and the dog.

  5. Site Preparation:

    • Clip the fur from the selected site to expose the vein clearly. Avoid using scissors or a razor, as they can cause injury.
    • Clean the area with an alcohol swab to remove any debris or contaminants that could affect the blood sample. Allow the area to dry for a few seconds.

  6. Venipuncture:

    • Locate the vein by gently palpating the selected site. The jugular vein, for example, runs along the side of the neck and can be felt pulsing beneath the skin.
    • Insert the needle into the vein at a 45-degree angle. It’s essential to maintain steady pressure as you advance the needle. You will feel a slight give or pop when the needle enters the vein.

  7. Blood Collection:

    • Once the needle is in place, attach the syringe and begin drawing blood gently. Be patient; it may take a few seconds for the blood to start flowing.
    • Collect the required amount of blood as specified by your veterinarian or laboratory instructions.

  8. Withdrawal and Care:

    • Withdraw the needle carefully and apply gentle pressure on the puncture site using gauze pads. Hold the pressure for at least 30 seconds to a minute to prevent bleeding and bruising.
    • Apply an adhesive bandage over the site to protect it from further injury or contamination.

  9. Disposal:

    • Dispose of the needle and other sharps in a designated sharps container according to safety guidelines.
    • Label the blood sample appropriately with the dog’s information and the date of collection before sending it to the laboratory.

  10. Post-Procedure Care:

    • Monitor the dog for any signs of discomfort or adverse reactions. Provide plenty of water to rehydrate if necessary.
    • Offer treats and praise to reinforce positive behavior during the procedure, making future experiences less stressful.

By following these detailed steps, you can safely and efficiently collect blood from a dog on an empty stomach while minimizing stress and potential complications.
