This study was made to investigate the arteriel blood blood supply of thoracic limb in dogs. In this study, 14 dogs were used. Latex and polyester resin were used in the investigation of the material.

Axillary artery supplies thoracic limb. Axillary artery divides into brachial and subscapular arteries between the sulbscapularis and the conjoined tendon of the teres major and latissimus dorsi.

The subscapular artery continues dorsocaudally between the subscapularis and teres major along the caudal border of the scapula towards its caudal angle. The circumflex scapular cranial and caudal circumflex humeral and thoracodorsal arteries arise from subsapulary artery.

The brachial artery is the distal continuation of the axillary artery in the arm. The brachial artery, after giving the deep brachial artery, the collateral ulnar artery, the superficial brachial artery, the transverse cubital artery and the common interosseus artery is termed median artery. From these arteries, medial branch of superficial antebrachial artery dosen't form dorsal carpal rete it directly continues as common dorsal digital artery.

The median artery gives the deep antebrachial artery, radial artery within the proximal third and fourth of the forearm respectively. The parent vessel forms palmar superficial arch. From this arch arise abaxial palmar digital artery V and palmar common digital arteries I, II, III and IV. From this arch arises abaxial palmar digital artery. V. Besides, dorsal branch of the ulnar artery continues as abaxial dorsal digital artery V.
