The '''popliteal a.''' supplies the stifle, gastrocnemius, popliteal muscle and terminates by branching into the cranial and caudal tibial arteries. 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.''' then supplies the main blood supply to the foot.
