When Does a Saint Bernard Stop Growing?

As a giant-sized working breed from Switzerland, the Saint Bernard reaches full height of 26–30 inches by approximately 15–24 months. Full adult weight of 120–180 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 Saint Bernard Overweight?

To determine if your Saint Bernard is at a healthy weight (120–180 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 double coat can mask weight gain, so hands-on assessment is essential. If your Saint Bernard 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 Saint Bernard approximately 1.8–3.6 cups of quality kibble daily, split into two meals. Males (120–180 lbs) may need slightly more than females (102–158 lbs). Males weigh 140-180 pounds, females 120-140 pounds; some exceed 200 pounds, though the breed standard favors proportional, powerful builds over sheer bulk.. With moderate energy (2/5), portions at the middle of guidelines usually suffice.
