How Big Do Yorkies Get? Size, Growth, and Care Tips

The Yorkshire Terrier, better known as the Yorkie, is one of the most popular toy breeds in the world. With their silky coats, confident strut, and affectionate personalities, these little dogs make a big impression. Yorkies are often chosen by families and individuals who love a small, portable companion that’s full of energy and charm. But before bringing one home, many new owners ask the same question: how big do Yorkies get, and what should I expect as they grow?

Yorkie Size in Different Periods

Yorkies grow quickly during their first year, and most reach their adult size by 12 months of age. Here’s a general guideline to help you understand their growth:
  
Age Average Weight Height Range
8 weeks 1–2 pounds 3–4 inches
3 months 2–3 pounds 4–5 inches
6 months 3–5 pounds 5–6 inches
9 months 4–6 pounds 6–7 inches
12 months 4–7 pounds 7–8 inches

  

Beyond the standard Yorkie size, some breeders refer to smaller variations called teacup Yorkies and mini Yorkies.
  • Teacup Yorkies: Usually weigh under 4 pounds and stay significantly smaller than the breed standard.
  • Mini Yorkies: Slightly larger than teacups but still below the standard Yorkie size of 4–7 pounds.

What Will Affect Yorkie Size

Not every Yorkie grows to the exact same size, and several factors can influence how big your pup will ultimately get:
  
  • Genetics: A Yorkie’s bloodline is the most important factor in determining size. Puppies from larger parents are more likely to grow on the higher end of the breed standard, while puppies from smaller lines may stay petite. Reputable breeders typically provide weight information from the puppy’s parents to give a better idea of expected adult size.

 

  • Nutrition: A high-quality, balanced diet is crucial for healthy growth and development. Proper protein, fats, and vitamins help puppies build strong bones and muscle. On the other hand, poor nutrition during the early months can stunt growth, cause weak bones, or lead to long-term health issues. Overfeeding, especially in small breeds, may also result in obesity, which makes them appear bigger but not healthier.

  • Health Conditions: Illnesses, parasites, or developmental issues during puppyhood can affect how much a Yorkie grows. Worm infestations, for example, may prevent a puppy from getting enough nutrients to develop properly. Chronic illnesses or genetic conditions can also slow down or limit growth. Regular vet checkups are important to ensure your puppy stays on track.

 

  • Exercise and Activity: While Yorkies don’t need as much exercise as larger breeds, regular activity helps them grow strong and stay lean. Daily short walks and playtime encourage healthy muscle development and prevent weight gain. Too little exercise can contribute to obesity, while too much high-impact activity can strain their small joints.

 

How to Take Care of a Yorkie

Because of their small size and delicate frames, Yorkies need a little extra attention to stay healthy, comfortable, and happy:
  
  • Balanced Diet: Feeding a Yorkie the right food is essential since toy breeds have fast metabolisms and small stomachs. High-quality dog food made for small breeds provides the right balance of protein, fat, and vitamins to support energy and keep their signature silky coat healthy. Be mindful of portion sizes — even a little overeating can lead to obesity, which puts extra strain on their joints and overall health.

 

  • Regular Grooming: Yorkies have long, fine, silky hair that is more like human hair than typical dog fur. Without consistent grooming, it can easily become tangled or matted, which can be painful and uncomfortable for your pup. Daily brushing helps keep the coat smooth and shiny, while professional trims every few weeks prevent overgrowth. Bathing every few weeks with a gentle shampoo also helps keep them clean and fresh.

  • Dental Care: Dental problems are one of the most common health issues in Yorkies. Their small mouths are prone to overcrowded teeth, tartar buildup, and gum disease. Regular brushing with a dog-safe toothpaste, along with dental chews or toys, helps maintain oral hygiene. Routine veterinary dental cleanings may also be necessary to prevent painful infections and bad breath.

 

  • Exercise and Play: While Yorkies don’t require long hikes or intense workouts, they still need daily exercise to stay fit and prevent boredom. Short walks, indoor games, and gentle play sessions are usually enough to keep them active. Because of their small frames, it’s important to prevent them from jumping off furniture or engaging in rough play, as injuries are common in such tiny dogs.

 

  • Protective Clothing: Yorkies have a fine coat and low body fat, which makes them more sensitive to cold weather than many other breeds. Lightweight shirts can keep them clean indoors, while sweaters or jackets provide warmth during outdoor walks in chilly weather. Clothing not only adds comfort but can also help protect their delicate skin from dirt, sun, and minor scratches.

 

How Big Do Yorkies Get?

So, how big do Yorkies get? On average, these tiny companions reach about 4–7 pounds in weight and stand 7–8 inches tall when fully grown. Their size may be small, but their personalities are anything but — Yorkies are confident, affectionate, and full of life. With consistent care, a nutritious diet, and lots of love, they can thrive as loyal, playful companions for many years. Whether you choose a standard Yorkie or a smaller variation, you’ll discover that their true size is measured not in pounds, but in the joy and devotion they bring to your home.
