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 '''median sacral a.''' arises from either the left or right internal iliac and supplies the sacrum and tail. The '''internal pudendal a.''' is the primary branch of the internal iliac and provides blood to the reproductive organs and urinary tract. The '''caudal gluteal a.''' supplies the superficial gluteal muscle and the proximal 'hamstring muscles'. The '''iliolumbar a.''' is the first branch of the caudal gluteal and supplies the psoas minor, iliopsoas, sartorius, tensor fascia lata and the middle gluteal muscles. The '''cranial gluteal a.''' arises from the caudal gluteal and passes over the greater ischiatic notch and supplies the gluteal muscles. The tail is supplied by the '''lateral caudal a.''' whilst the '''dorsal perineal a.''' supplies the perineum.

The '''popliteal a.''' supplies the stifle, gastrocnemius, popliteal muscle and terminates by branching into the '''cranial and caudal tibial aa.'''. The '''cranial tibial a.''' supplies the peroneus longus, long digital extensor and cranial tibial muscles whilst the '''caudal tibial a.''' is a small branch that lies in the interosseous space between the tibia and fibula. The '''dorsal pedal a.''' is a continuation of the '''cranial tibial a.''' and runs over the flexor surface of the tarsus and supplies the tarsus. The  '''arcuate a.''' branch is the main blood supply to the foot. The '''dorsal metatarsal aa.''' supply the paw dorsally whilst the '''perforating branch''' (of the) '''metatarsal aa.''' forms an anastomoses with the caudal branch of the '''saphenous a.''' and contributes to the plantar metatarsal arteries that supply the digits.
