Growth is not a promise
Puppy growth depends on breed size, genetics, nutrition, health, and sex. Use the result as a range, not an exact prediction.

FAQ
How big will my puppy get?
Breed size and current growth pattern can suggest a broad range, but no calculator can predict adult size exactly.
When do puppies stop growing?
Small breeds may mature around 9-12 months, while large and giant breeds can keep growing for 18-24 months.
Why do large-breed puppies grow differently?
Large breeds grow for longer and need careful nutrition to support steady development.
Important note
Puppy growth estimates are broad guides and are not a substitute for veterinary growth checks.
