How many grams of food should I feed my German Shepherd?

This depends on your dog's weight, activity level and the specific food's calorie density, so the feeding guide on your chosen food is the right starting point rather than a fixed figure. Adjust gradually based on how your dog's weight and body condition track over a few weeks.

Should I feed my German Shepherd once or twice a day?

Twice a day is generally recommended for adult German Shepherds, partly because large deep-chested breeds carry a higher risk of bloat, and splitting the daily amount into two meals rather than one large one is considered a sensible precaution. Ask your vet if you have specific concerns about your dog's feeding routine.

Why does my German Shepherd seem hungry all the time?

Some German Shepherds are simply food-motivated and will act hungry regardless of how much they are fed, but persistent, unusual hunger is also worth mentioning to your vet, since it can occasionally point to something else needing attention. Checking body condition alongside appetite gives a fuller picture.

Do working German Shepherds need more food than pet dogs?

Generally, yes — a genuinely active or working dog burns more energy than a mostly sedentary pet of the same size, and it is reasonable to feed more accordingly, ideally using a food formulated for active dogs. The right amount still needs checking against your individual dog's body condition rather than assumed from its role alone.

How much should I feed my German Shepherd?

There is no single daily amount that fits every German Shepherd, because the right portion depends on your individual dog's weight, age, activity level and the specific food you feed. The method that works reliably is starting from the feeding guide on your chosen food, checking it against your dog's body condition, and adjusting gradually from there — which matters more than memorising a number, since German Shepherds vary a lot in size and energy between individual dogs and lines.

Start with the feeding guide on the food

Every commercial dog food carries a feeding guide on the packaging, usually a table matching body weight to a daily amount, and this is the correct starting point rather than a generic figure quoted for the breed. Different foods vary in calorie density, so the right amount of one brand can be quite different from the right amount of another for the same dog.

German Shepherds are a large, active breed, typically weighing somewhere in the region of 22 to 40kg as adults depending on sex and line, working dogs at the more active end of that range generally needing more than a mostly sedentary pet Shepherd of the same weight.

Check it against body condition, not just weight

Weight alone does not tell you whether a dog is carrying the right amount of condition, since two Shepherds of the same weight can differ in build and muscle. A simple check most owners can do at home is feeling for the ribs with light pressure — they should be easy to feel without being visibly prominent — and looking for a visible waist from above.

If your dog is gaining or losing weight steadily over a few weeks despite feeding the guide amount, that is the signal to adjust the portion gradually, rather than waiting for a much bigger change to become obvious.

Adjusting for activity and life stage

A working or highly active German Shepherd genuinely needs more food than a similarly sized dog living a quieter life, and this is a reasonable, evidence-based adjustment to make rather than overfeeding without cause. Puppies, pregnant or nursing dogs, and senior dogs also have different needs from a healthy adult, generally covered by switching to a food formulated for that life stage rather than simply feeding more or less of an adult recipe.

If you are ever unsure whether your German Shepherd's current amount is right, your vet can assess body condition properly at a check-up and advise on adjusting portions for your individual dog, which is more reliable than any general guide, including this one.
