When to call your vet
- Body condition is 3 or lower, or 7 or higher, on the 9-point chart.
- Weight drops, or stays the same across two weigh-ins while your puppy should still be growing.
- Your puppy seems unwell: not eating, vomiting, diarrhea or low energy.
How the Yorkshire Terrier chart reads
The Yorkshire Terrier was #13 in the AKC’s 2025 popularity ranking. Of the 9 breeds with a fitted chart on this site, the Yorkshire Terrier has the 2nd lightest top weight, shared with another breed at 7 lb.
The AKC chart gives only an upper weight for the Yorkshire Terrier. To draw a band we set the low end at 70% of it, 4.9 lb. That lower edge is our own assumption, not an AKC figure. The whole range sits inside our toy class (under 12 lb), so this page uses the toy growth curve.
On the typical toy curve, a puppy has about 67% of its adult weight at 16 weeks, 89% at 26 weeks and 100% at 1 year. For a Yorkshire Terrier, that puts the 16-week band at 3.1–5.0 lb and the 26-week band at 4.2–6.5 lb. Our toy curves reach 99% of adult weight at 40 weeks for an early maturing puppy, 46 weeks for a typical one and 52 weeks for a late one.
Montoya et al. (2023) estimated a life expectancy at birth of 13.36 years for purebred toy dogs, against 12.69 years across all dogs in their data. That is a figure for the size class, not for Yorkshire Terriers specifically.
Our toy curve is derived from a growth study of 65 Toy Poodles (Menchetti et al. 2020), read from its abstract (open question D5 on our methodology page). We found no growth study for other toy breeds.
About the Yorkshire Terrier data
Salt et al. (2017), who built growth standards from veterinary clinic records, name the Yorkshire Terrier as an example breed for their size category I (<6.5 kg adult weight).
How it’s calculated
The table starts from the AKC adult range. At each age, the low end is the bottom of the range times the share of adult weight a late maturing toy puppy has, and the high end is the top of the range times the share for an early maturing one. The calculator on this page works the other way round: it starts from your puppy’s weight today.
Mixed breed or not sure of the breed? The puppy size calculator works from a size class or “Not sure” instead. Every step, source and open question is on our methodology page.

How big will a Yorkie puppy get?
The AKC lists adult Yorkshire Terriers (Yorkies) at up to 7 lb (up to 3.2 kg). Enter your puppy’s age and weight in the calculator on this page to see where in that range they’re heading.
