How this was calculated
For a Yorkshire Terrier we use the toy-breed growth curve (matures around 10 months): adult weight ≈ current weight ÷ the fraction of adult weight a toy breed reaches at this age. Typical adult weight (4–7 lb) is from the AKC breed standard. The gauge shows where your prediction lands against the breed-typical adult range.

Yorkshire Terrier growth, explained
Yorkshire Terriers are a toy breed, so they follow the toy-breed growth curve. AKC standard: not to exceed 7 lb. A toy breed — most of the growing is done early. Most reach close to their adult weight by around 10 months, then continue to firm up in muscle and chest for a while after.
To predict an adult weight we divide your puppy’s current weight by the fraction of adult weight a toy breed has typically reached at that age. Typical adult weight (4–7 lb) is from the AKC breed standard. The result is an estimate with a likely range — genetics and nutrition move individual dogs up or down. If your Yorkshire Terrier looks heavier or lighter than the breed-typical band, your vet is the best person to check.
