The lateral saphenous vein is the most effective vessel for rabbit venipuncture. The lateral saphenous runs more caudal on the limb that you would expect and bifurcates in two smaller branches going distal, forming an inverted “Y”. My favorite spot to hit the vessel is right proximal to the bifurcation. I also try to only use 1-ml syringes in small to medium size rabbits, since they allow to apply a gentler negative pressure. With larger syringes there is risk of collapsing the vein. We’ll discu
