Best German Shepherd Food →How much to feed an adult German Shepherd, by weight
Daily calories and cups of dry food at 380 kcal per cup, split across two meals. Read down to your dog’s weight and across to the activity level that matches its week.
| Adult weight | Low activity | Moderate | High | Working |
|---|---|---|---|---|
| 50 lb | 873 kcal · 2.3 cups | 1018 kcal · 2.7 cups | 1164 kcal · 3.1 cups | 1309 kcal · 3.4 cups |
| 60 lb | 1001 kcal · 2.6 cups | 1168 kcal · 3.1 cups | 1335 kcal · 3.5 cups | 1501 kcal · 4.0 cups |
| 65 lb | 1063 kcal · 2.8 cups | 1240 kcal · 3.3 cups | 1417 kcal · 3.7 cups | 1594 kcal · 4.2 cups |
| 70 lb | 1124 kcal · 3.0 cups | 1311 kcal · 3.5 cups | 1498 kcal · 3.9 cups | 1685 kcal · 4.4 cups |
| 75 lb | 1183 kcal · 3.1 cups | 1380 kcal · 3.6 cups | 1578 kcal · 4.2 cups | 1775 kcal · 4.7 cups |
| 80 lb | 1242 kcal · 3.3 cups | 1449 kcal · 3.8 cups | 1656 kcal · 4.4 cups | 1863 kcal · 4.9 cups |

| 90 lb | 1357 kcal · 3.6 cups | 1583 kcal · 4.2 cups | 1809 kcal · 4.8 cups | 2035 kcal · 5.4 cups |
Activity multipliers: low 1.2, moderate 1.4, high 1.6, working 1.8. Body condition beats the table: if you cannot feel ribs under light pressure, feed less than the number says.
Puppy portions by age and typical weight
Puppy portions follow current weight, not age, so each row pairs an age with the weight a male German Shepherd puppy typically carries at that point. Weigh your puppy and use the row nearest its actual weight.
| Age | Typical weight | Daily calories | Cups per day | Meals | Cups per meal |
|---|---|---|---|---|---|
| 2 months | 16 lb | 619 kcal | 1.6 | 3 | 0.5 |
| 3 months | 26 lb | 891 kcal | 2.3 | 3 | 0.8 |
| 4 months | 35 lb | 1113 kcal | 2.9 | 3 | 1.0 |
| 6 months | 53 lb | 1520 kcal | 4.0 | 2 | 2.0 |
| 8 months | 64 lb | 1751 kcal | 4.6 | 2 | 2.3 |
| 10 months | 70 lb | 1873 kcal | 4.9 | 2 | 2.5 |
| 12 months | 75 lb | 1380 kcal | 3.6 | 2 | 1.8 |
Female puppies run roughly 15 percent lighter at every checkpoint. Growth weights come from the puppy growth reference, and the puppy feeding chart covers the food-type and large-breed constraints behind these numbers.
How This Calculator Works
We use the Resting Energy Requirement (RER) formula recommended by veterinary nutritionists: 70 x (body weight in kg)^0.75. This is then multiplied by an activity factor to get your dog's daily calorie needs.
Activity factors range from 1.0 for sedentary or senior dogs up to 2.0 or higher for working German Shepherds. Intact dogs generally need slightly more calories than spayed or neutered ones.
The cup-per-day estimate is based on average calorie density for each food type. Your specific food may vary — check the label for exact kcal/cup and adjust accordingly. Most standard kibble runs 350-400 kcal per cup, while high-performance formulas can exceed 500 kcal per cup.
Example: Feeding a 70lb Adult German Shepherd
A 70lb (31.8kg) moderately active adult German Shepherd has a resting energy requirement of about 897 calories (70 x 31.8^0.75). With a standard activity multiplier of 1.6, the daily calorie target comes to roughly 1,435 calories.
Using a standard kibble at 380 kcal per cup, that works out to about 3.8 cups per day — split into two meals of roughly 1.9 cups each, morning and evening. At a typical kibble price of $2.50 per pound, monthly food cost runs approximately $60-$80.
If that same dog is highly active — regular running, agility, or protection work — the multiplier jumps to 2.0, bringing daily needs closer to 1,794 calories and roughly 4.7 cups per day. Working dogs or dogs with high energy demands may need a high-calorie performance formula to keep portions manageable.
German Shepherd Feeding Tips
- Split into 2 meals minimum — German Shepherds are at high risk for bloat (GDV). Feeding one large meal increases this risk significantly.
- Don't free-feed — measured meals help you track intake and spot health issues early. Sudden appetite changes are often the first sign of illness.
- Wait 30 minutes after eating before exercise — another important bloat prevention measure. Avoid vigorous play immediately before meals as well.
- Adjust for body condition — you should be able to feel (but not see) your German Shepherd's ribs. Adjust portions up or down based on this, not just the calculator output.
- Transition food gradually — when switching brands or formulas, mix old and new food over 7-10 days. German Shepherds are known for sensitive stomachs, and sudden changes often cause digestive upset.
