The small saphenous vein is not typically used for venipuncture. This vein runs along the back of the leg and is deeper and more difficult to access compared to other veins, such as the median cubital vein in the arm. Additionally, it is primarily used for venous drainage of the lower limb rather than for blood draws. Venipuncture is usually performed on veins that are more superficial and easier to palpate.
The median cubital vein is best for venipuncture because it is generally the largest and best-anchored vein.
The three common sites for venipuncture in dogs are the cephalic vein, located on the front leg; the jugular vein, found in the neck; and the femoral vein, located in the inner thigh. The cephalic vein is often preferred for its accessibility and ease of handling, while the jugular vein allows for larger volume draws. The femoral vein is typically used in specific cases, such as when other sites are not viable. Proper restraint and technique are essential for successful venipuncture.
The medial cubital or celphalic
You use your thumb to keep the vein from "rolling" while doing a venipuncture.

When selecting a site for venipuncture, it is best to start with the veins running through the antecubital area. First, locating the Median Antecubital Vein, Cephalic Vein, and Basilic Vein. If unsuccessful with venipuncture, then approaching the dorsum of the hand, and lastly the dorsum of the foot.
To prevent a vein from rolling during venipuncture, it's essential to stabilize the vein by applying gentle traction to the skin distal to the insertion site. Use your non-dominant hand to anchor the skin and keep it taut, which helps secure the vein in place. Additionally, selecting an appropriate vein, typically one that is palpable and visible, can reduce the likelihood of rolling. Proper positioning of the patient and using a larger gauge needle can also support successful venipuncture.

A venipuncture is a puncture in a vein. As when a person gives blood or has a blood test run.
