Because dogs vary so much in size, there is no single standard chart for puppy growth. Guidelines for weight are determined by the puppy's breed. PetMD provides a healthy weight calculator for purebred and mixed breed puppies and dogs.
As a species, dogs are remarkable in their variation. There are tiny toy breeds like the Yorkshire Terrier and giant breeds like the Great Dane. Moreover, dogs have various body types. Dachshunds are long and low, greyhounds are lean and sleek, and bulldogs are dense and stocky. Given these differences, ideal adult and puppy weights vary among breeds.
Different breeds also grow at different rates. Small breeds mature more quickly and can reach full adult size and weight by the age of 1. Large breeds can take up to two years to reach maturity.
