The circle of Willis in the dog is supplied from three sources; paired internal carotid arteries laterally and the basilar artery caudally. The internal carotid artery is a terminal branch of the common carotid artery. The internal carotid artery blood reaches all of the cerebral hemisphere except for it's most caudal part. Vertebral blood supplies the the remainder of the cerebral hemisphere and the rest of the brain. Vertebral arteries are responsible for almost all supply to the occipital lobes of the cerebral hemisphere in the dog.
