What are the three most common venipuncture sites in dogs?

The three most common venipuncture sites in dogs are the cephalic vein, saphenous vein, and jugular vein.

The cephalic vein is located on the front leg, running along the lateral aspect of the forelimb. It is often the first choice for venipuncture due to its accessibility and the ease with which it can be palpated, making it ideal for routine blood draws and intravenous access.

The saphenous vein is located on the hind leg and is another commonly used site. It is especially useful in smaller breeds or when the cephalic vein is not accessible. However, it is important to note that this vein is sometimes more difficult to locate than the cephalic vein.

The jugular vein is a large and prominent vein located in the neck, making it an excellent choice for larger volumes of blood collection or when rapid access is needed. It is often preferred when performing more invasive procedures or when multiple samples are required.

Together, these three sites are frequently used due to their anatomical convenience and the varying situational needs during blood collection. They provide reliable access while minimizing pain and stress to the pet.
