What combination of low weight and minimal height makes the Yorkshire Terrier incredibly portable?

Answer

Weight no more than seven pounds and height rarely above eight or nine inches

The portability of the Yorkshire Terrier stems directly from its stature as a toy breed, defined by specific dimensional limits. The standard dictates a weight ceiling of seven pounds. Correspondingly, their height is also very low to the ground, with an adult rarely exceeding eight or nine inches measured at the shoulder. This minimal size, combining low weight and short stature, is what defines them as easily transportable companions, though this delicacy also necessitates careful handling.
