What each stage means for a Standard Schnauzer

Young adult (1–3): still learning. Keep training consistent and set the healthy weight now; for a Standard Schnauzer that is usually within 30–50 lb.
Mature adult (3–10): yearly checkups, dental care and steady exercise. Watch the waistline as activity drops.
Senior (11+): many vets suggest checkups every six months, plus attention to joints, teeth and weight changes.

How much a Standard Schnauzer eats

A spayed or neutered adult around 40 lb needs roughly 980 calories a day, about 2.6 cups of a typical 380-calorie-per-cup dry food. See the full feeding guide for a 40 lb dog.
