At sixteen weeks, the Yorkies I've known have been tiny — often just a few pounds, commonly somewhere in the 2–4 pound zone, though lines vary and some run larger. Here's the part that surprises big-dog people: a sixteen-week Yorkie is a meaningful fraction of its way to adult size, while my goldens at the same age are barely a third of theirs. The puppy coat is soft and often darker than the adult steel-and-tan; the famous silky floor-length coat, if you keep it long, is years of grooming away. What hasn't finished growing is the self-image, which is already set to "wolfhound."
A Yorkie at 16 weeks
My goldens outweigh a sixteen-week Yorkie by the time they're eight weeks old, so I write this page as the big-dog friend who has spent years around two Yorkie households — including one puppy who grew up in our training class, four pounds of dog with forty pounds of opinion.
The shape of the dog
Temperament: the big dog in the small body
The sixteen-week Yorkie in our class was the most self-assured animal in the room, including the instructor. Terrier confidence shows early: bold investigation, a quick sharp bark at anything irregular, and absolutely no awareness of being small. That fearlessness is charming and slightly dangerous — the biggest risk at this age isn't the Yorkie's temperament but everyone else's size. The owners I know were careful about playmates (calm, gentle dogs only), careful underfoot, and careful with kids who don't yet know the difference between a puppy and a plush toy. A scared-on-the-ground Yorkie also learns to be carried everywhere, which builds a barky, anxious adult — the better path our classmate took was protected floor time: real experiences, curated company.
Training stage — and the potty-training honesty
Smart, quick, and a little self-employed: the class Yorkie learned sit and name response as fast as any retriever, but worked for the joy of being clever rather than to please. Short, game-like sessions won; repetition bored him into freelancing. And here's the honesty every Yorkie owner I know volunteers: potty training small breeds tends to take longer. Tiny bladders, a metabolism that runs fast, and accidents small enough to miss (which silently un-trains the schedule) all conspire. The fix is the same system from the first-days entry run with extra rigor — more trips, more vigilance, longer timeline, zero shame. Expect potty training to still be a live project at sixteen weeks; that's normal for the size.
Energy and exercise
Yorkie energy is real but apartment-scaled: a couple of short walks, indoor play, and a good shredding session cover the day, and the five-minutes-per-month guideline lands at a very manageable twenty minutes. Two cautions from the Yorkie households I know: watch the jumping — off couches and beds especially, since small-breed knees are a known soft spot your vet will happily lecture about — and watch the cold, because a few pounds of puppy loses heat fast. The general 16-week entry still applies in full: teething (those tiny teeth still fall out on schedule), the open world, the possible fear period.
From a Yorkie friend's notebook: "treat him like a dog, not an accessory, and he'll act like a dog." The best-adjusted small dogs I know were raised with big-dog rules at small-dog scale.

The Frenchie at sixteen weeks is the other small-package page, with very different caveats; the breeds hub has the full set, and the milestones timeline covers what doesn't change with size.
Questions I get asked a lot
How big is a Yorkie at 16 weeks?
Tiny — the ones I've known were often somewhere around 2–4 pounds at this age, though lines vary and some run larger. Unlike the big breeds, a sixteen-week Yorkie is well along toward adult size. Your vet's read on the individual growth curve beats any range here.
Why is my 16-week-old Yorkie still having accidents?
Because small-breed potty training honestly takes longer: tiny bladder, fast metabolism, and accidents small enough to go unnoticed — which quietly un-trains the schedule. Run the standard system with extra trips and extra vigilance, and expect the project to extend past sixteen weeks. It gets there.
Are Yorkies fragile?
Physically, somewhat — a few pounds of puppy is at real risk from rough play, big-dog enthusiasm, couch jumps, and feet that don't see them. Temperamentally, not remotely: the breed's confidence is enormous. The job at this age is protecting the body without smothering the personality — curated playmates and real floor-level experiences.
Do Yorkies bark a lot at this age?
The terrier alert-bark typically shows up early — quick and sharp at anything irregular. The Yorkie owners I know got the best results by rewarding quiet-after-alert from the start rather than waiting for the habit to harden. A bored or constantly-carried Yorkie barks more; engagement and floor time help.
Every puppy is different — please confirm timing, doses, and anything health-related with your veterinarian. This journal is one owner's experience, not veterinary advice.
