Summary

There has been a recent increase in the use of trained dogs in animal-assisted therapy programmes. This morphological study uses the Nigerian local dog as a prototype dolichocephalic to determine rostrofacial parameters which are of clinical and anesthesiological importance in veterinary oral surgery and intervention. Sixteen Nigerian local dog skulls of both sexes (seven males and nine females) were used. The females were observed to have higher values for most of the parameters measured. Statistically significant difference (P<0.05) was only observed in one parameter, distance between the mandibular foramen and the caudal border of the mandible, with the female value being higher. The length of the mandible from the most rostral point of the dental bone to the most caudal projection of the coronoid process (MDL-1) showed a positive correlation to the parameters depicting height, width and length of the mandible. Results obtained from this study will find application in veterinary comparative anatomy and in clinical application in oral and maxillofacial surgery and anaesthesia, especially in regions where the dental x-ray is not readily available.

KEY WORDS: Nigerian local dog; Rostrofacial indices; Regional anaesthesia; Skull; Morphology.
