The acetabulum is contributed to by all of the above bones. The acetabulum is surrounded by an ''acetabular rim'' and the depth of the acetabulum varies depending on breed, shape of pelvis and hip conformation.

In canines the wings of the ilium are much more oblique conformation when compared to large animals and this allows the muscles of the pelvis floor to be displaced laterally over a wider area when compared to the vertebral column. This increases the efficiency and therefore power of the abdominal muscles which allows a greater degree of flexibility of the vertebral column which is essential for faster locomotion and agility. Canines also have relatively caudal displaced ''ishial tuber'' which increases the leverage of the hamstring muscles onto the hindlimbs providing further efficiency improvements for locomotion.
