Salukis are fast, tall and lean: they are used in the dessert to chase down rabbits and offer protection, their bone structure is similar to that of a cheetah, making them fast and agile with 12 ft stride. Downsizing the breed is done by only breeding smallest to the smallest. Pekinese are 2000 years old, created by chinese as a symbol of chinese. Buddhism (buddha had tamed the lion for protection so the chinese turned to dogs to create their symbol: earliest breed standard. Small breeds started coming about in for a status symbol, lab dogs were big in victorian age: started dog breeding for aesthetic reason rather than purpose. Thyroid releases thyroxin until the growth is done, controls growth rate: theory: thyroxin rhythms are different in different breeds, contributing to vast differences in sizes.
