Yorkshire Terrier Growth Stages

Understanding the typical growth stages helps you know what to expect as your Yorkshire Terrier puppy grows.

Neonatal

0–2 weeks

Puppies are born with eyes and ears closed, relying entirely on their mother. Rapid weight gain occurs during this period.

Socialization

3–12 weeks

Eyes and ears open. Puppies begin to explore, play, and learn social behaviors. This is a critical period for development.

Juvenile

3–6 months

Rapid growth continues. Puppies become more independent, start teething, and develop coordination.

Adolescent

6–9 months

Growth rate begins to slow. Puppies reach sexual maturity and may test boundaries. Muscle mass develops.

Young Adult

9–12 months

Growth is nearly complete. Your puppy is filling out and approaching adult proportions.

Adult

12+ months

Your puppy has reached their full adult size. Weight should remain relatively stable with proper nutrition.

How much will my Yorkshire Terrier puppy weigh as an adult?

As a toy breed, Yorkshire Terriers usually reach an estimated adult range of 4–7 lb overall. Sex matters: males typically finish around 4–7 lb and females around 4–7 lb. Track weekly weigh-ins to see whether your puppy trends toward the lower or upper end.

At what age is a Yorkshire Terrier fully grown?

Yorkies finish quickly as toy dogs, often stabilizing before 12 months. Overall, Yorkshire Terriers—classified as toy—usually mature between 9 and 12 months. Puppies may look nearly full-sized before muscle and bone fully settle, which is normal and expected for this breed.

How do male and female Yorkshire Terrier weights compare by age?

Male and female Yorkshire Terriers share a similar typical adult range, so their estimated puppy ranges often overlap at each age. Use the chart as a growth trend in lb or kg and compare several weigh-ins rather than treating one number as a fixed target.
