Yorkshire Terrier full grown

A full grown Yorkshire Terrier weighs up to 7 pounds and stands 7 to 8 inches at the shoulder. That ceiling is the AKC breed standard, not an average, so a Yorkie over 7 pounds is simply over the standard rather than unusual. Most Yorkies reach their adult weight by about ten months.

Fair. Four to five months is the usual time to make this estimate. It is reasonable now, but the range is still wide.

Estimate only. For health questions, ask your vet. Mixed breeds can land outside the range.

In short

Key takeaways

  1. A full grown Yorkshire Terrier weighs 4 to 7 lb across all its sizes.
  2. The weight and height here come from the official breed standard.
  3. Most of the growing is done by about 10 months.
  4. A long coat means regular paid grooming, which is a real yearly cost.
  5. "teacup" is a seller's word, not a recognized size.

The AKC standard gives 7 pounds as the weight and 7 to 8 inches as the height. The 4 pound floor is ours, for drawing the chart.

Timing

When a Yorkshire Terrier stops growing

In our figures, a dog in the toy size class has done almost all of its weight gain by about 10 months. After that the weekly gain drops below a quarter of a percent of adult weight, which is slow enough that you will not see it on the scales week to week.

Height finishes earlier than weight. The AKC puts small breeds at full size by 6 to 8 months, medium breeds at around 12 months, and giant breeds at 12 to 18 months, with some very large breeds taking up to 24.

Variation

Why individual Yorkshire Terriers differ

The AKC standard puts a ceiling on a Yorkie rather than a range. Plenty of pet Yorkies weigh 8 or 9 pounds and are perfectly healthy; they are just outside what a show ring wants.

A Yorkie puppy that is tiny at eight weeks is not necessarily going to stay tiny. Litter position and early feeding both affect early weight more than adult size does.

Sales words

"teacup" is not a size

You will see Yorkshire Terrier puppies advertised as "teacup", "micro", "pocket". None of those is a recognized variety in any registry.

The Chihuahua Club of America, writing about its own breed, lists “Teacup, Pocket Size, Tiny Toy, Miniature or Standard” as labels attached to the breed and calls them incorrect and misleading, used to make a puppy seem more valuable. The same reasoning applies wherever the words turn up.

A puppy sold under one of these labels grows up as an ordinary Yorkshire Terrier, usually at the light end of the range and sometimes not. The label tells you nothing useful about adult size. Your puppy's own weight does, which is what the calculator on this page uses.

Running cost

Grooming a Yorkshire Terrier

A long coat is a running cost, and it is worth knowing the figure before you take a puppy home rather than after. The price per groom goes up with the size of the dog.

FAQ

Questions people ask

How big is a Yorkshire Terrier full grown?
4 to 7 pounds across every size this breed comes in, standing 7 to 8 inches at the shoulder. Those figures come from the breed standard.
How can I tell how big my Yorkshire Terrier puppy will get?
Weigh your puppy and enter its age in the calculator on this page. It is already set to the toy growth curve for this breed, so it works backwards from where your puppy is now rather than from the breed average. Four to six months is when the estimate is most reliable.
How often does a Yorkshire Terrier need grooming?
A long coat needs a groom every 4 to 8 weeks under published guidance. Over a year that adds up, and the grooming cost estimator works out what it comes to for a dog this size.
When does a Yorkshire Terrier stop growing?
Weight gain slows to almost nothing at around 10 months for a dog in the toy size class. Height finishes earlier than weight in every breed.
How much should a full grown Yorkie weigh?
The AKC standard says 7 pounds. Pet Yorkies commonly finish between 4 and 9 pounds, and your vet judges a healthy weight by body condition rather than by the number on the scale.
Is a teacup Yorkie a real thing?
No registry recognizes a teacup size. The Yorkshire Terrier standard has one weight and no smaller variety beneath it. When a breeder uses the word, it is a price label on a small Yorkie, and deliberately breeding for very low weight brings health risks with it.
How big will a teacup Yorkie get?
A puppy sold as a teacup Yorkie grows up as a Yorkshire Terrier, usually at the light end, so 2 to 4 pounds in some cases and a normal 5 or 6 in others. Nothing about the label makes the adult size predictable. Use the calculator above on your own puppy's weight instead.
When do Yorkies stop growing?
Most are at adult weight by ten months. The AKC puts small breeds at full size by 6 to 8 months, and our own figures show the last few percent arriving slowly after that.

How we calculate this

The adult weight and height come from the sources below. The shape of the growth chart comes from our own calculation on the open data behind a published veterinary growth standard, described on the how we calculate page. The charts are estimates built from a breed range and a population curve, not measurements of this breed.
