The '''abdominal aorta''' terminates by branching into the '''external iliac arteries''' and the '''internal iliac arteries'''. It is these arteries that supply the hindlimb and pelvis.

The first branch of the '''femoral a.'''is the '''superficial circumflex iliac a.''' which supplies the sartorius, tensor fascia lata and rectus femoris. The '''lateral circumflex femoral a.''' which branches off the '''superficial circumflex iliac a.''' supplies the quadriceps, tensor fascia lata, the superficial and middle gluteals, and the hip joint capsule. The '''proximal caudal femoral a.''' is the second branch from the '''femoral a.''', branching at the mid-thigh region and supplying the pectineus, adductor muscles and gracilis. The third branch is the '''saphenous a.''' which arises proximal to the stifle and supplies the skin on the medial aspect of the stifle. The '''saphenous a.''' also has cranial and caudal branches. This artery and its vessels lie very superficially and the cranial branch gives rise to the '''dorsal common digital aa.''' and the caudal branch gives rise to the '''plantar common digital aa.'''; both of which supply the foot. The branches following the '''saphenous a.''' in order are the '''descending genincular a.''' supplying the medial surface of the stifle, the '''middle caudal femoral a.''' supplying the distal parts of the adductor and semimembranosus muscles and the '''distal caudal femoral a.''' which is the last branch of the '''femoral a.''' before it becomes the '''politeal a.'''. It supplies the biceps femoris, semimembranosus, semitendinosus, gastrocnemius and the digital flexors.
