Giant Schnauzer feeding guide: how much and how often
Daily calories, portions by age and practical feeding tips for the Giant Schnauzer.
An active 40 kg (88 lb) male might eat 400 to 550 g of dry food a day, roughly 4 to 5.5 cups, split into two meals. Females and quieter dogs need less; dogs in serious sport or working training may need more. Use body shape as the guide, since energy levels vary enormously between lines.
Like many large, deep-chested breeds, the Giant Schnauzer can be prone to bloat. Split food into at least two meals, avoid vigorous activity for an hour around feeding and keep mealtimes calm. Some Giants inhale food, and a slow feeder helps. Seek emergency care if your dog retches without producing anything, has a swollen belly or seems restless and distressed after eating.
Some lines carry an inherited form of cobalamin (vitamin B12) malabsorption, which usually shows in young puppies as poor appetite and failure to thrive. Buy from breeders who DNA test for it, and tell your vet promptly if a puppy is not growing as expected or seems unusually tired.

Puppy portions need measured weight, growth stage and the food’s energy content. A breed-average curve is not a feeding plan. Calculate with measured inputs and review the result with your vet.
