Great Dane Puppy Feeding Chart

How much should I feed my Dane Puppy?

* Please note that the weights are only approximations. Danes can grow at wildly different rates. If your dog does not fall in these ranges, it dose not necessarily mean something is wrong. Consult your vet if you feel your Dane is not growing properly

Dyhas still recommends feeding on a calorie basis over cup basis. All dog foods are different per cup. Use this chart for a baseline though to figure out where to start with calorie couting.

Time Period Est. Weight Amount
2 Months 15-30 lbs 2-4 cups
3 Months 25-45 lbs 3-5 cups
4 Months 45-65 lbs 4-6 cups
5 Months 60-80 lbs 5-7 cups
6 Months 65-100 lbs 6-8 cups
7 Months 70-110 lbs 6-9 cups
8 Months 80-120 lbs 6-9 cups
9 Months 85-125 lbs 7-10 cups
10 Months 95-130 lbs 7-10 cups
11 Months 100-140 lbs 2-4 cups
12 - 18 Months 100-155 lbs 7-10 cups

Dog Food Calculator

If you really want to know how much calcium you are feeding

I created the dog food calculator for my own personal use when I was searching for food to feed Hank when he was a puppy. Hank has some food intolerance issues and thus I needed to do trials on many different foods, but I wanted to make sure they had acceptable levels on a per calorie basis to the more traditional kibble fed to Giant Breeds. But the main factor behind its creation came from when I was reading the Michigan State study which mentioned the following:

Often puppies are switched from growth to maintenance diets to avoid calcium excess and skeletal disease. However, because maintenance diets are generally of much lower energy density than growth diets, the puppy must consume more dry matter volume to meet its energy requirement. If the calcium levels (dry matter basis) are similar between the two diets, the puppy will actually consume more calcium on the maintenance diet.

I found this to be quite an eye opener. In addition, I spoke a nutritionists at the FROMM dog food company that explained to me that cups of different dog food do not weigh the same. These two factors led me to a.) Go to a calorie based diet and not cup based diet, b.) That numbers don't lie and unless you do the math you really don't know if your puppy is getting too much or too little calcium.

You will need Microsoft Excel to use the calculator

1. Download the calculator here.

2. Gather the following information for the dog food you wish to check. Most of this should be on your dog food label but you may have to visit the website or call the company to get the calcium and phosphorus levels.

  • kcal per cup
  • % Protein
  • % Fat
  • % Calcium
  • % Phosphorus
  • ** Kcal per gram
** Kcal per gram may not be listed on your bag.

Instead it may say something like 468 kcal per 250ml/120g cup. You will have to do the math here and divide 120g into 468 kcal. This will give you how many kcal are in a single gram of dog food. If weight is not listed you will need to contact the company to get the kcal per gram.

3. Enter the values from above into white fields of the calculator.

4. View the results in the blue highlighted section.

The results are based on a 2000 calorie diet. Using a typical Great Dane cup feeding chart this would be for a Great Dane between 3-4 months old. You can adjust the formula by going into the fields in Columns I and J and switching 2000 to what ever calories you wish to compare against.


Using a popular common Giant Breed dog food with moderate protein, and low fat and calcium as our baseline, we can now compare how your dog food stacks up. A few things should become pretty clear as you begin to read through the numbers. First and foremost is that calorie based feeding is far more reliable than cup based feeding. We included a few examples of other dog foods for you to compare against. If for example you were feeding NutriSource Grain Free on a cup based diet instead of calories, you would be feeding considerably more calories, protein, and calcium. But when you base it on Calories, you will see that there is not a huge difference in the amount of protein, fat and calcium fed compared to our baseline food. Again, we believe that the age old moderate protein, low fat and low calcium is so prescribed because most people would not go through this much trouble to calculate it out.

Secondly, look at the so called High protein food like Orijen. Protein being excluded (please read the Trinity tab if you are not sure why) there is not that much difference in calcium intake and fat. You would expect a a food that has such a high % of fat (18%) compared to the baseline food at (12.5%) to give much more than fat a day than the baseline. But in fact you are only giving 21gs more than the baseline food.. However, the fat is a bit to high and because of that I would not recommend until after 1 year old.

In addition

The calculator is not meant to be a definitive test only to give you an idea of how foods stack up. Further complicating the issues is some foods have a min/max value particularly on Calcium. For example, the Orijen Regional Red listed on the calculator has a min. 1.6% calcium and max 1.9% calcium. This means the food can fall anywhere in between those to numbers in regards to % calcium. When this is the case we recommend going with the mean of the two numbers. Also, the calculator is meant to be used in accordance with the slow and steady rule. You will adjust caloric intake up and down as your puppy grows and use the "last rib" rule.
