Alsatian - Age/Weight
Every dog and each circumstance of its genetic heritage and life environment vary, so all data are approximations.
At birth, a German Shepherd puppy of a standard litter of six to eight pups would be expected to weigh approximately 1% of the dam's pre-pregnancy weight. This varies depending on a number of factors, including but not limited to genetics, size of litter, gender, and environmental conditions for the dam and pups during pregnancy and whelp.
The healthy newborn large breed pup is expected to at least double its birth weight at one week of age, then experience a period of consistent daily weight gain of 5-10%, moderating to a rate of gain that ultimately reaches at physical maturity about 70 or more times the puppy's birth weight (see chart below).
The German Shepherd Dog typically reaches physical adulthood at 18-24 months of age, with some Eastern European bloodlines maturing even more slowly, sometimes not until 36+ months of age. However one would expect to see the rate of growth slow demonstrably after about 6 months of age, with minimal weight gain after 12 months of age in the appropriately maintained dog.
