For saphenous venipuncture, what position should the dog be in?

For saphenous venipuncture, having the dog in lateral recumbency is the preferred position because this allows clear access to the saphenous vein, which is located on the medial aspect of the hind leg. When a dog is lying on its side, the leg is naturally more extended and relaxed, making it easier to visualize and palpate the vein for successful blood draws. This position also reduces stress and movement from the dog, leading to a safer and more efficient procedure.

In contrast, while standing and sitting positions might be practical for some venipuncture sites, they do not provide the same degree of access and control as lateral recumbency does for the saphenous vein. Sternal recumbency, where the dog is lying on its chest, also does not facilitate easy access to the saphenous vein, as it requires the leg to be manipulated in a way that is less comfortable for the dog. Thus, lateral recumbency is optimal for this specific procedure.
