Growth Chart

When Does a Giant Schnauzer Stop Growing?

As a giant-sized working breed from Germany, the Giant Schnauzer reaches full height of 23–27 inches by approximately 15–24 months. Full adult weight of 55–85 lbs follows within a few months as the dog fills out.

Nutrition during the growth phase is critical. Given the breed's predisposition to Hip Dysplasia, proper growth-rate management is especially important.

Is My Giant Schnauzer Overweight?

To determine if your Giant Schnauzer is at a healthy weight (55–85 lbs target):

Rib test: You should be able to feel the ribs without pressing hard, with a thin layer of fat covering them
Waist check: Viewed from above, there should be a visible waist behind the ribs
Tuck-up: From the side, the abdomen should tuck up behind the rib cage

Their wire coat can mask weight gain, so hands-on assessment is essential. If your Giant Schnauzer is overweight, work with your veterinarian to develop a safe weight loss plan. Even a 10% reduction can reduce the risk of Hip Dysplasia and other conditions.

Feeding Recommendation

Feed an adult Giant Schnauzer approximately 0.8–1.7 cups of quality kibble daily, split into two meals. Males (55–85 lbs) may need slightly more than females (46–74 lbs). Males weigh 60-85 pounds, females 55-75 pounds; the breed should appear powerful and compact, with a square build that conveys strength and agility.. Active individuals with energy rated 4/5 may need portions at the higher end of guidelines.
