How Big Do Yorkies Get?

One of the most appealing things about Yorkshire Terriers is their tiny size. If you are thinking about getting a Yorkie, or if you have a growing puppy at home, you probably want to know exactly how big your dog is going to get. The answer depends on a few factors, but Yorkies are one of the smallest dog breeds out there.

A standard adult Yorkie typically weighs between 4 and 7 pounds and stands 7 to 8 inches tall at the shoulder. Some Yorkies fall slightly outside this range, and factors like genetics, diet, and overall health all play a role in their final size.

Yorkie Size by Age

Yorkies grow quickly during their first year of life, with most reaching their full adult size by about 12 months. Here is a general timeline of what to expect as your Yorkie grows.

At birth, Yorkie puppies weigh just a few ounces. By 8 weeks old, they typically weigh around 1 to 2 pounds. At 3 to 4 months, most Yorkies weigh between 2 and 3.5 pounds. By 6 months, they are usually close to their adult weight at around 3 to 5 pounds. By 12 months, most Yorkies have reached their full size of 4 to 7 pounds.

Some Yorkies continue to fill out slightly after their first birthday, but any significant growth after 12 months is unusual.

What Determines a Yorkie’s Size?

Genetics

The biggest factor in your Yorkie’s adult size is genetics. If both parents were on the smaller side, your puppy is likely to be smaller too. If the parents were closer to the 7 pound mark, expect a larger Yorkie. Meeting the parents or asking the breeder about their sizes gives you the best prediction of how big your puppy will grow.

Diet

Proper nutrition during the first year is essential for healthy growth. A Yorkie fed a high quality, balanced diet will develop properly and reach its genetic potential. Overfeeding can lead to an overweight Yorkie that exceeds the breed standard, while underfeeding can stunt growth and cause health problems.

Health

Underlying health issues can affect a Yorkie’s growth. Parasites, infections, and certain genetic conditions can slow development and result in a smaller than expected adult dog. Regular vet checkups during the first year help make sure your puppy is growing on track.

Standard Yorkies vs. Teacup Yorkies

You may have heard the term “teacup Yorkie,” which refers to Yorkies that weigh 4 pounds or less as adults. It is important to understand that teacup is not an official breed designation recognized by any major kennel club. These are simply very small Yorkies, and their tiny size often comes with serious health risks.

Teacup Yorkies are more prone to hypoglycemia, fragile bones, dental problems, and organ issues due to their extremely small size. They require extra careful handling and more frequent meals to keep their blood sugar stable. If you are considering a teacup Yorkie, make sure you understand the additional health care requirements involved.

Can Yorkies Be Bigger Than 7 Pounds?

Yes, some Yorkies grow larger than the breed standard of 7 pounds. A Yorkie that weighs 8 to 10 pounds or even more is not unheard of, and it does not necessarily mean anything is wrong. Larger Yorkies sometimes come from lines where a slightly bigger breed was mixed in at some point in the dog’s ancestry, or they may simply be at the larger end of the genetic spectrum.

An oversized Yorkie can still be a perfectly healthy and wonderful pet. However, if your Yorkie is gaining weight rapidly or seems significantly larger than expected, check with your vet to rule out any health issues and make sure the dog is not simply overweight from overeating.

How to Keep Your Yorkie at a Healthy Weight

Because Yorkies are so small, even a pound or two of extra weight can have a big impact on their health. Feed your Yorkie a measured amount of high quality food rather than free feeding. Limit treats to no more than 10 percent of their daily caloric intake. Provide daily exercise through walks and play to keep them active. Regular weigh ins at home or at the vet help you catch any weight changes early.
