How big do German Shepherds get?

The full adult size of your GSD will depend in large part on the genetic background of its parents. Adult males should range between 24-26" at the shoulder blade, females from 22-24". Males within the standard may weigh anywhere from 65-90 lbs. depending on their bloodlines. Females may weigh anywhere from 50-75 lbs. Although your pup will reach close to adult height by 10-18 months, he will continue to fill out until up to 3 years old.
