A total of 20 parameters were measured using an osteometric board and digital vernier caliper. Six parameters were found to be significantly higher (P  <  0.05) in males than in females, while one parameter was significantly higher (P  <  0.05) in females than in males. However, none of the measured parameters demonstrated clear cut-off values with no intersect between males and females. Therefore, we generated a stepwise discriminant analysis from all 20 parameters in order to develop a possible working equation to discriminate gender from a dog pelvic bone. Stepwise discriminant analysis was used to create a discrimination function: Y = [82.1*PS/AII] − [50.72*LIS/LI]  − [23.09*OTD/SP] + [7.69*SP/IE]  + [6.52*IC/OW] + [7.67*ISA/OW]  + [20.77*AII/PS] + [504.71*OW/ISA]  − [90.84*PS/ISA] − [148.95] , which showed an accuracy rate of 86.27%. This is the first study presenting an equation/function for use in discriminating gender from a dog's pelvic measurements. The results can be used in veterinary forensic anthropology and also show that a dog's pelvis presents sexual dimorphisms, as in humans.
