The external iliac artery is the principal artery of the hindlimb. Once it branches from the aorta it runs along the ilial body. Prior to entering the '''femoral canal''' (formed by the sartorius cranially and the gracilis and pectineus caudally) it detaches the deep femoral artery and on leaving the abdomen the external iliac continues as the femoral artery. The femoral artery continues between the adductor muscles on the medial aspect of the thigh to reach the caudal side of the stifle. Here it continues as the popliteal artery.

Below are the arteries in order in which they branch off the external iliac, femoral and popliteal arteries:

Below are the arteries in the order in which they branch off the external iliac, femoral and popliteal arteries:

** '''Lateral circumflex femoral a.''' - branches off with the superficial circumflex; it supplies the quadriceps, tensor fascia lata, the superficial and middle gluteals, and the hip joint capsule.

** '''Lateral circumflex femoral a.''' - branches off with the superficial circumflex; it supplies the quadriceps, tensor fascia lata, the superficial and middle gluteals, and the hip joint capsule.

** '''Proximal caudal femoral a.''' - branches off at the mid-thigh region and supplies the pectineus, adductor muscles and gracilis.  

** '''Proximal caudal femoral a.''' - branches off at the mid-thigh region and supplies the pectineus, adductor muscles and gracilis.  

** '''Saphenous a.''' - arises proximal to the stifle and supplies the skin on the medial aspect of the stifle. It branches into a cranial and caudal branch. This artery and is vessels lie very superficially. The cranial branch gives rise to the '''dorsal common digital arteries''' and the caudal gives rise to the '''plantar common digital arteries'''; both of which supplie the foot.
