An adult Giant Schnauzer weighs 60-85 lbs (male) or 55-75 lbs (female), needs 1,090-2,170 calories daily, and lives 12-15 yrs. Large breeds need portion control and joint-conscious exercise, especially during growth. The breed's primary health watch is hip dysplasia. All numbers below come from AKC breed standards and NRC 2006 veterinary nutrition formulas.
Nutrition and feeding
A typical adult Giant Schnauzer needs 1,090 to 2,170 calories per day. An average male (72 lbs / 32.9 kg) needs around 1,630 kcal; a female (65 lbs / 29.5 kg) roughly 1,510 kcal. These estimates use the vet-standard RER/MER formula.

Health profile
Large breeds face a particular set of health challenges related to their size and growth rate. The Giant Schnauzer typically lives 12-15 yrs. The breed's primary health concerns are hip dysplasia and bloat, which responsible breeders screen for before breeding.
Exercise and activity
60-90 minutes of vigorous daily exercise. Powerful and athletic breed that needs both physical and mental work. Working breeds like the Giant Schnauzer were developed for specific physical tasks. They need purposeful activity, not just wandering around a yard. Structured exercise with clear tasks, such as carrying a dog pack on hikes, pulling a cart, or advanced obedience training, satisfies their need to work. Without sufficient exercise, the Giant Schnauzer is likely to develop destructive behaviors, excessive barking, or anxiety. This is a breed that needs daily commitment to physical activity.
Care and traits
Giant Schnauzers have a dense, wiry double coat coat. Origin: Germany (Bavaria).
The largest of the three Schnauzer sizes. Requires regular professional grooming (hand-stripping for show dogs, clipping for pets). Strong-willed breed that needs experienced, confident owners.
Grooming is a significant time commitment with this breed. Plan for daily brushing sessions and professional grooming every 4-6 weeks. Skipping grooming leads to mats, skin irritation, and potential infection underneath tangled coat.

Frequently asked questions
Daily calorie needs for a Giant Schnauzer range from 1090 to 2170 kcal. A 72-pound individual falls near the middle of that range. Avoid high-calorie puppy foods designed for small breeds. Large breed puppies need moderate calorie density with controlled calcium and phosphorus. Active dogs need more; seniors and less active individuals need less. Use our calorie calculator with your dog's actual weight for a personalized number.
Males typically weigh 60-85 lbs (27.2–38.6 kg). Females run lighter at 55-75 lbs (24.9–34.0 kg). Large breeds carry weight in the midsection and over the ribs. A visible waist from above and a tuck behind the ribs when viewed from the side indicate healthy condition. Check body condition by feeling the ribs (they should be easy to find), viewing from above (waist should narrow behind the ribs), and from the side (abdomen should tuck up behind the ribcage).
If you own a Giant Schnauzer, hip dysplasia is the condition your vet will likely screen for first. Hip dysplasia is a developmental condition where the hip joint doesn't fit together properly. Screening through OFA or PennHIP before breeding is standard practice. In pet dogs, maintaining a lean body weight is the most effective way to manage and slow progression. Other conditions seen in the breed include bloat, autoimmune thyroiditis, osteochondritis dissecans. Regular vet visits with breed-specific screening catch problems when they are most treatable.
The Giant Schnauzer is built for activity and needs 60 to 90 minutes of daily exercise. Good activities for this breed include structured tasks, cart pulling, obedience drills. Mental stimulation through training and puzzle toys is as important as physical exercise for this breed. An under-exercised Giant Schnauzer will find outlets for pent-up energy, often in ways you will not appreciate: chewing, barking, digging, or restless pacing.
