In this study, a total of 23 humeri of German shepherd puppies of ages between 40 and 100 days were used. It was observed that the proximal and distal epiphyseal regions were not closed and even the epiphysis was partially spongious. The width of the epiphyseal plate and epiphysis were not equal and they reached the same level with age. There were variations between the epiphysis widths of the right and left humeri and the differences between these values were statistically significant. When the right and left humeri measurements were analysed for correlation with each other, a significant high positive correlation was determined statistically.
