Great Dane portions by weight
| Adult weight | RER | Daily target | Kibble / day | Cups / day | Per meal (×2) | Raw / day |
|---|---|---|---|---|---|---|
| 50.0 kg | 1,316 kcal | 2,106 kcal | 512 g | 5.1 | 256 g | 1,000 g |
| 64.5 kg | 1,593 kcal | 2,549 kcal | 620 g | 6.2 | 310 g | 1,290 g |
| 79.0 kg | 1,855 kcal | 2,968 kcal | 722 g | 7.2 | 361 g | 1,580 g |
Neutered adult (×1.6), kibble at 370 kcal/100 g, 10% treat allowance removed. Raw at 2.0% of body weight (size-correct rate). Cups ≈ grams ÷ 100 (typical kibble — weigh in grams for accuracy).
Worked example: a 64.5 kg Great Dane
A 64.5 kg adult Great Dane (neutered): RER 1,593 × 1.6 = 2,549 kcal − 255 kcal treats ÷ 3.7 kcal/g = 620 g — that is 310 g per meal, twice a day. The same arithmetic runs in the calculator above: change the weight or the life stage and every number follows.
Great Dane puppy feeding by age
| Age | Factor | Meals / day | Note |
|---|---|---|---|
| Under 4 months | ×3.0 | 3–4 | On current weight — weigh every 2 weeks |
| 4–8 months | ×3.0 → ×2.0 (taper) | 3–4 | Factor falls smoothly — weigh every 2 weeks |
| 8–12 months | ×2.0 | 3 | 3 meals; 2–3 from 6 months |
| 12 months to adult | ×1.6–1.8 | 2 | Adult factor from 18–24 months |
Factors multiply RER on the puppy's current weight, not adult weight. Large and giant breeds keep the growth factors until 18–24 months.
Feeding notes for the Great Dane
For a sedentary giant, the inactive factor is not a diet — it is maintenance. Giants hide fat under heavy coats and loose skin; judge condition by ribs and waist, never by appetite or the empty bowl.
What makes feeding a Great Dane different: Giant breeds carry the highest bloat risk and the longest growth window: split meals, rest after eating, and keep a Dane puppy lean — never feed for size. Extra weight on a 60 kg frame is carried by joints that were never built for it.
Health, treats and the senior years: Great Danes are prone to heart disease, and extra weight makes a struggling heart work harder — keeping one lean is the single most useful feeding decision. In old age, watch the appetite and the energy: a Dane that tires easily or goes off food is a vet visit, not a portion change.
Training, treats and everyday feeding: Great Danes do best on two or three smaller meals a day rather than one large one — a deep-chested giant should never eat a big meal and then exercise. A slow-feeder bowl is worth more than a raised bowl, and rest for an hour after eating is the standard precaution for this breed.
Weight & condition for the Great Dane: Giant breeds carry the highest bloat risk and the longest growth window: split meals, rest after eating, and keep a Dane puppy lean — never feed for size. Extra weight on a 50–79 kg frame is carried by joints that were never built for it; weigh monthly, and feed a slimming Dane for its target weight, not its current one.
Body condition check: Judge the portion by the dog, not just the table: on the 9-point body condition scale, aim for 4–5 — ribs easily felt under a thin fat cover, a waist visible from above, a tuck from the side. If you can't feel the ribs, feed 10% less than the table even if the weight looks right; if ribs show, feed 10% more.
Puppies of this size class reach adult factors at about 18–24 months; until then, growth portions follow the puppy factors (×3.0 under 4 months, tapering to ×2.0 by 8 months) on current weight, recalculated every two weeks. Individual dogs vary by up to ±50% from any formula — the scale and your hands on the ribs outrank this table.

Great Dane feeding questions
How much food should a Great Dane eat per day?
Across the full adult weight range (50–79 kg), a Great Dane needs about 2,106–2,968 kcal/day — 512–722 g of typical kibble (370 kcal/100 g) after the 10% treat allowance is removed — depending on weight, sex and activity. A typical adult at the middle of the range (64.5 kg) needs about 2,549 kcal/day, roughly 620 g, split over 2 meals.
How many meals a day should a Great Dane eat?
Two or three smaller meals a day is right for a Great Dane — split the daily 620 g (2,549 kcal) for a 64.5 kg adult across them, never served as one big bowl. A deep-chested giant should never eat a large meal and then exercise, and the one-hour rest after eating is the standard precaution in this breed. A slow feeder is worth more than a raised bowl, and puppies should never be fed 'to grow'.
How many cups of food does a Great Dane need per day?
About 620 g/day is roughly 6.2 cups at the typical density of 100 g per cup — but cups vary by up to 40% between kibbles, so weigh the grams once and the question disappears. A cup is a volume; grams are the portion. At 620 g a day, a 10% scooping error is about 62 g — a small dog's entire meal — so weighing matters more, not less, as portions grow.
How do I switch a Great Dane to a new food?
Over 10–14 days for a giant breed: 25% new food for 3 days, 50% for 3–4 days, 75% for 3–4 days, then 100% — keeping the total daily grams at the number on this page throughout. Giant breeds do best with gradual changes and smaller, more frequent meals; if stools loosen, hold at the current mix for an extra two days before moving on.
How much should a Great Dane puppy eat?
Giant puppies are the longest, most delicate growth project: adult factors only at 18–24 months. Use ×3.0 under 4 months, tapering to ×2.0 by 8 months, on current weight, keep them visibly lean, and never 'feed for size' — genetics sets the size, calories only set the fat.
How much raw food does a Great Dane need?
At the size-correct BARF rate of 2.0% of ideal body weight, a 64.5 kg Great Dane eats about 1,290 g of raw food per day — split 70% muscle meat, 10% raw edible bone, 5% liver, 5% other organ, 10% vegetables and fruit on the BARF model.
How does feeding a Great Dane change as they age?
From about 18–24 months a Great Dane counts as fully adult; the senior shift usually arrives years later, when activity and muscle mass fall. The calculator's senior factor (×1.4 instead of ×1.6) trims a 64.5 kg Great Dane from 2,549 to about 2,230 kcal/day — roughly 543 g of typical kibble. Make the change gradually and judge by body condition, not birthdays alone: a still-active older Great Dane may hold condition on the adult number.
How do I feed a Great Dane puppy safely?
Lean and slow: giant puppies grow for 18–24 months, and excess calories accelerate the frame faster than joints can follow. Use the puppy factors (×3.0 under 4 months, tapering to ×2.0 by 8 months) on current weight, keep the puppy visibly slim, and never add food to grow a bigger Dane — genetics sets the size, calories only set the fat.
How much does a Great Dane eat in a month?
A lot: a 64.5 kg adult at 620 g/day eats about 18.6 kg of kibble a month. Budget by that number — and remember the raw equivalent is about 1,290 g/day at 2.0% of body weight, which is roughly 38.7 kg a month.
