Great DaneFeeding Chart: How Much to Feed by Age & Weight
A healthy adult Great Dane (110–175 lb) eats a lot: roughly 2,100–3,000 calories a day, or about 6 to 8½ cups of dry food. Always split that across two meals rather than one big bowl — the Great Dane is among the breeds at greatest risk of bloat, a risk tied to its deep, narrow chest (the AKC source is in the feeding section below).
Great Dane puppies are the harder feeding job. Giant breeds grow for nearly two years, and growing too fast strains developing joints — so they need a giant-breed puppy food and shouldn't move onto adult food until around 18–24 months. The chart below gives sourced starting points by weight; the calculator tailors them to your dog.

Daily Feeding Amounts by Weight & Age
Find your dog's current weight in the chart for an estimated daily amount. Calories come from the Merck Vet Manual energy formula; cups assume a typical ~350 kcal/cup dry food, so check your bag's label for its exact kcal/cup.

These are healthy-dog starting points, not a strict rule — body condition and activity vary. Confirm your dog's target with your veterinarian. For your exact dog, use the calculator below.
Is my puppy a healthy weight for its age?
Rather than one “correct” weight, vets track puppies against evidence-based growth standards that run from 12 weeks to 2 years.
Those standards are grouped by a dog's adult body size (up to 40 kg), not by individual breed.
We don't publish a per-age “your puppy should weigh X” figure — that belongs on a vet's growth chart, weighed over time. What we give you instead is the daily caloriesfor your dog's actual weight today (the chart above and the calculator below), every number cited.

The plan for a typical Great Dane
🐕 Here's the plan for your Great Dane
Healthy puppy (4 months+) · 4 months old · 60 lb
1668 cal/day · ~4.8 cups · 3 meals/day
🍽 HOW MUCH YOUR GREAT DANE PUPPY SHOULD EAT
Your little one is growing fast — and that takes fuel. About 1668 calories a day will keep your great dane on a healthy track.
Puppies have small stomachs and growing bodies that want food often. As your dog grows, you'll feed less often:
- • 6 to 12 weeks: 4 meals a day
- • 3 to 6 months: 3 meals a day ← your puppy now
- • 6 to 12 months: 2 meals a day
- • After age 1: 2 meals a day
Just look up your puppy's age in months and pick the row that matches.
- •The Great Dane is among the breeds at greatest risk of bloat: its tall, narrow chest — a high height-to-width ratio — is what drives the elevated risk.
💧 Water~60 oz/day▼
A good rule of thumb: a weaned puppy needs about ½ to 1 ounce of water per pound of body weight each day. The numbers below use the higher end as a safe target — most dogs settle in somewhere in this range.
Keep the bowl filled with fresh water.
🍬 Treatsup to 167 cal/day▼
Treats are great for training and bonding — but they should be the bonus, not the main course.
- • 90% of daily calories from real dog food
- • 10% from treats, chews, table scraps — anything extra
🛒 How to choose dog food▼
Walking into the pet store can be overwhelming. But you only need to check the back or side of the dog food bag for these things:
- ☐ The bag has an AAFCO Nutritional Adequacy Statement that mentions “growth”Look for a full sentence on the back or side of the bag containing both “AAFCO” and “growth”. Typical wording is one of two formats:
- “[Brand] is formulated to meet the nutritional levels established by the AAFCO Dog Food Nutrient Profiles for growth.”
- “Animal feeding tests using AAFCO procedures substantiate that [Brand] provides complete and balanced nutrition for growth.”
For large-breed puppies (adults expected to exceed 70 lb), the statement should also mention large size dogs. - ☐ “Calories per cup” is printed on the bagUsually in the feeding guide section. You need this number to know exactly how much to scoop for your dog.
- •The Great Dane is one of the large/giant breeds the FDA named in its investigation of a potential link between certain grain-free diets and canine dilated cardiomyopathy (DCM). Talk to your vet before choosing a grain-free formula for a Great Dane.
🚫 FOODS TO KEEP AWAY FROM YOUR GREAT DANE
Some everyday human foods are dangerous — even tiny amounts can cause serious harm. Keep these well out of reach:
Never feed: chocolate, xylitol (sugar-free gum / candy / some peanut butters), grapes, raisins, onions, garlic, macadamia nuts, alcohol, caffeine, avocado.
⚠️ Xylitolis a sweetener that's safe for humans but can be deadly to dogs. If your dog ingests anything containing xylitol, call your vet right away.
- Free-feeding (leaving food out all day). It sounds convenient but makes portion control and weight monitoring much harder.
- Switching food suddenly. Transition over 7-10 days — mix the new food with the old in growing proportions to avoid an upset stomach.
- Switching to adult food too early. Puppy formulas are higher in protein than adult formulas — tuned for the demands of growth. When to actually switch? Small breeds (under 20 lb) at 8-12 months; medium breeds (20-50 lb) around 12 months; large breeds (50+ lb) at 12-15 months; giant breeds at 18-24 months.

🩺 QUESTIONS TO BRING TO YOUR VET
Save or print this list and bring it to your next visit.
- ❓ “What body condition score is my Great Dane at now, and what's the ideal?”Why ask: The 1-9 body condition score is the standard vets use to tell if your dog is at a healthy weight.
- ❓ “Is my Great Dane puppy's growth rate on track?”Why ask: Large breeds are sensitive to growing too fast. Your vet can compare current weight to the expected range for this age.
- ❓ “When should we transition from puppy to adult food?”Why ask: For large breeds the transition can be later than 12 months — your vet can advise based on actual growth.
- ❓ “Are there breed-specific screenings or watches for Great Danes at this age?”Why ask: Great Danes have known breed traits worth monitoring — your vet may suggest preventive screening based on age and lineage.
Great Dane feeding — common questions
- How much should I feed an adult Great Dane?
- A healthy adult Great Dane (about 110–175 lb) needs roughly 2,100–3,000 calories a day — about 6 to 8½ cups of dry food, split into two meals. The exact cups depend on your food's kcal per cup (check the bag); see the adult row matching your dog's weight.
- How many times a day should a Great Dane eat?
- Two meals a day for adults — never one large bowl. The Great Dane is among the breeds at greatest risk of bloat, and how you feed is one lever you can control. Growing puppies eat 3–4 smaller meals.
- How much should a Great Dane puppy eat?
- A Great Dane puppy under 4 months is fed about 3× its resting energy needs across 4 small meals; from 4 months it steps down to roughly 2× across 3 meals. Find your puppy's current weight in the puppy rows of the chart above for an estimated daily amount — and don't overfeed: fast growth is hard on a giant-breed puppy's joints.
- When should a Great Dane switch from puppy to adult food?
- Giant breeds like the Great Dane grow the longest — plan to keep yours on giant-breed puppy food until about 18–24 months so growth isn't rushed. Your vet can confirm the timing based on your dog's actual growth.
- Are grain-free diets safe for a Great Dane?
- The Great Dane is one of the large and giant breeds named in the FDA's investigation into a potential link between certain 'grain-free' diets and canine dilated cardiomyopathy (DCM). Talk to your vet before choosing a grain-free formula for a Great Dane.
- How do I know if my Great Dane is overweight?
- A general body-condition check: you should be able to feel the ribs without pressing through fat, with a visible waist tuck behind the ribcage. If the ribs are buried, scale portions back and confirm a target weight with your vet.
