What is the strictly dictated maximum weight for the modern Yorkshire Terrier standard?
Not more than 7 pounds
The modern breed standard places a heavy emphasis on maintaining the dog's diminutive size, reflecting its successful transformation into a lap companion where portability is valued. While the early working specimens varied more widely in their physical dimensions, current official guidelines are highly prescriptive regarding weight. Specifically, the modern standard mandates that a Yorkshire Terrier must weigh no more than 7 pounds. This strict adherence to a small package size contrasts sharply with the initial functional requirement for size, which was dictated by the need to navigate cramped industrial spaces, highlighting that the modern constraint is primarily aesthetic and companion-oriented.
