From Tiny Newborns to Confident Little Gems
Yorkie Puppy Development Stages
A cute week-by-week guide to the changes families may see as a Yorkshire Terrier puppy grows. Every puppy develops at an individual pace, so milestones are educational guidelines rather than guarantees.
For families: This chart is a general developmental guide, not a veterinary schedule or guarantee. Smart Yorkies LLC follows each puppy individually and veterinary recommendations take priority for health care, vaccines, deworming, nutrition and readiness to go home.

Yorkshire Terrier Growth Estimates
A reference tool for following puppy growth—not a guarantee of adult size.
Size disclaimer: Yorkshire Terriers grow at different rates. Genetics, nutrition, health and development all matter. Any adult-weight projection is an estimate only. Smart Yorkies LLC does not guarantee mature weight or size.

Building our own Smart Yorkies data: We will track our puppies' actual birth, weekly and adult weights over time. As our own dataset grows, Smart Yorkies LLC can develop a program-specific growth reference based on our lines rather than presenting outside calculations as proprietary Smart Yorkies data.
