Is there a caudal thyroid artery in the dog (Canis familiaris)?

Attempts have been made to establish extent of similarities as well as dissimilarities between the canine caudal thyroid and human inferior thyroid artery. On the basis of origin, course, relationship, branching pattern, major area of supply, level of anastomosis, occurrence, etc., it is proposed to rename the caudal thyroid of the dog as the tracheoesophageal artery.
