This study aimed to explain the sex determination of the autochthonous dog Deltari Ilir with both morphometric and geometric analysis methods. For this purpose, 24 Deltari Ilir dog skulls (12 females and 12 males) were used in the study. The difference between males and females at 6 values was statistically significant. The most statistically significant difference was seen in the measurement of the greatest breadth of the occipital condyles (p < 0.000). This measurement was higher in male skulls. The next most significant difference was seen in the greatest inner height of the orbit measurement (p < 0.002). This measurement was also higher than for females. In general, the skull length measurements of male dogs were higher than that of females. Male dog skulls had greater skull length and skull height. The lateral view was used for geometric analysis and 14 landmarks were determined. As a result of principal component analysis, 22 PC values were obtained. PC1 accounted for 23.73% of the total variance. As a result of canonical variants analysis, it was observed that males and females were completely separated from each other. The caudal part of the males was wider than the females in geometric analysis. As a result of the study, sex-determining characteristics were revealed for the Deltari Ilir dog. It was seen that gender analysis could be done with both morphometric and geometric analysis methods. In addition, it was seen that morphometric results and geometric analysis results supported each other. Moreover, the results of the study will be useful in the function of comparative anatomy, in veterinary clinical practice, in zooarchaeology but why not also in the veterinary forensic investigation.
