Ranges cover both males and females. Mixed breeds can land anywhere between the parents, so ask your vet to track the growth curve.
What the numbers mean
The adult range is the weight the American Kennel Club gives for the breed, covering males and females. Some breed standards give a single target ("about 7 lb") instead of a range.
The AAHA 2019 Canine Life Stage Guidelines say the puppy stage lasts until rapid growth stops, usually between 6 and 9 months depending on breed and size. Large and giant breeds keep filling out for longer after that.
The percentage compares your puppy's weight now with the middle of the adult range. It is a progress check, not a prediction: puppies grow at different speeds, and your vet's growth chart for your puppy is the best guide.
For mixed breeds, the parents' sizes are the best clue, if you know them.

Frequently asked questions
When do puppies stop growing?
Rapid growth usually stops between 6 and 9 months, depending on breed and size, according to the AAHA life stage guidelines. Bigger breeds keep maturing after that.
Can you tell adult size from paw size?
There is no reliable rule based on paws. The breed's standard weight range and your vet's growth checks are better guides.
