Abstract :Objective: In this study, the developmental status of the thoracic Limb bones of a 40-day-old watchdog hybrid fetus was studied. Materials and Methods: Bones of 40-day-old animals were dyed with Inouye technique. Dissections of the bones stored in appropriate solutions were performed. Photographs were taken with a stereomicroscope and a digital camera. Measurements were taken from the dissected legs with a 150 mm Mitutoyo brand caliper. Results: It was observed that some of the thoracic limb bones of a 40-day-old watchdog hybrid had a primary ossification center (POC), while some bones did not have a primary and secondary ossification center (SOC). Primary ossification centers were observed in the bodies of the bones of the scapula, humerus, radius, ulna, and ossa metacarpus of the fore limb, but no ossification centers were observed in the proximal and distal ends. Furthermore, ossification centers were not observed in the carpal bones and ossa digitorum manus. Conclusion: The formation status and dimensions of POC seen in the bones of the forelimbs of a 40-day-old guard dog hybrid fetus were determined. The ossification centers in guard dog hybrid fetuses were consistent with studies conducted in a large number of domestic animals. As a result, it should mark the ossification in various features such as hormones, environmental factors, and individual variations.
