AKC Yorkshire Terrier Size Standard

The AKC standard specifies Yorkshire Terriers should not exceed 7 lbs. In practice, AKC Yorkies from well-bred lines typically weigh 4–7 lbs. Yorkies under 4 lbs carry significantly elevated health risks.

Teacup Yorkies: The Honest Assessment

Teacup Yorkies — typically under 4 lbs — are not AKC-recognized. They carry elevated risks of hypoglycemia, tracheal collapse, patella luxation, liver shunts, and bone fractures from minor falls. Ethical Yorkie breeders do not selectively breed for extreme smallness.

When Do Yorkies Reach Full Size?

Yorkshire Terriers reach adult height by 8–10 months and adult weight by 10–12 months. The silky coat and blue-and-tan coloration continue developing through the first two years of life.
