Follow typical puppy weight from eight weeks to adulthood, compare male and female ranges, and estimate adult size.
Compare modeled male and female curves and place your puppy’s measurement on the chart.
Age ranges are scaled from imported adult endpoints.

No. It is an educational size-curve estimate, not a diagnosis or guarantee.
Adult weight, height and lifespan use structured database values.
A size curve scales adult endpoints; values are not observed.
Individual puppies may grow differently.
