Yorkshire Terrier Breed Overview

The Yorkshire Terrier, affectionately called the Yorkie, originated in 19th-century England, where it was bred as a skilled rat-catcher in textile mills. Over time, its charming looks and spirited personality made it one of the most beloved companion dogs worldwide. Yorkies are lively, intelligent, and affectionate, often forming close bonds with their families while also carrying a confident, sometimes feisty, demeanor.

As a toy breed, the Yorkshire Terrier typically weighs under 7 lbs as an adult. Because of their tiny size, growth tracking is especially important—small fluctuations in weight can indicate health issues, and overfeeding can quickly lead to obesity, which puts strain on their delicate bones and joints (American Kennel Club).

Yorkshire Terrier Growth Chart & Weight Ranges

Age	Average Weight Range
4 weeks	12–20 oz (0.75–1.25 lbs)
8 weeks	1–2 lbs
3 months	1.5–3 lbs
6 months	2.5–4.5 lbs
9 months	3–6 lbs

Gender differences: Males are often on the slightly heavier side of the scale, though the difference is typically less than 1 lb compared to females.

How Much Bigger Will My Yorkshire Terrier Puppy Get?

• Most Yorkie puppies reach 50% of their adult weight by 3 months of age.
• They usually finish growing by 9–12 months, with some taking up to 15 months to fill out.
• A common rule of thumb: Double your Yorkie’s weight at 12–16 weeks for a reliable adult size estimate.

Note: Since Yorkies are a toy breed, they mature faster than medium or large breeds and do not experience extended growth periods.

Yorkshire Terrier Growth Tips

Nutrition

• Feed a high-quality toy-breed puppy food formulated for small mouths and fast metabolisms.
• Offer 3–4 small meals per day until 6 months old, then transition to 2–3 meals daily.
• Monitor portions carefully—Yorkies are prone to hypoglycemia (low blood sugar) as puppies, so consistent feeding is essential.

Exercise

• Short daily walks and gentle playtime are sufficient for Yorkie puppies.
• Avoid rough play or high jumps, as their small bones are fragile.
• Mental stimulation (puzzle toys, short training sessions) is just as important as physical activity.

Health Watch

• Toy breeds like Yorkies are vulnerable to patellar luxation (knee issues) and tracheal collapse, so controlled growth and proper weight are vital.
• Dental problems are common—introduce tooth brushing early.
• Regular vet checks help catch growth or metabolic issues early (VCA Animal Hospitals).
