The dog calorie calculator takes crude ash, crude fat, crude fiber, crude protein, how many days do you need food for?, dry matter, energy content in food and weight and returns amount of food for given the number of days, your dog should eat and your dog needs. It is built for quick answers, for checking somebody else’s arithmetic, and for the moments when a formula book is not within reach.
What Is the Dog Calorie Calculator?
The dog calorie calculator works out amount of food for given the number of days, your dog should eat and your dog needs from crude ash, crude fat, crude fiber, crude protein, how many days do you need food for?, dry matter, energy content in food and weight.
Biological relationships are usually approximations rather than exact laws, so the output is best treated as an estimate with a sensible range around it.
How the Dog Calorie Calculation Works
The calculation applies the relationship as published, step by step, so each intermediate value can be checked against the underlying theory.
Keep the units consistent throughout. Mixing a percentage with a proportion is the single most common source of an answer that is out by a factor of a hundred.
Assumptions Worth Knowing
Any relationship used here assumes a constant rate, a representative sample, or a stable population. Real populations rarely meet those conditions for long, so treat the answer as a guide.
Where the inputs are field measurements, a single misread value can shift the result noticeably. Measure carefully and record what you used.
A Worked Example
Working through an example, with crude ash set to 10, crude fat set to 5, crude fiber set to 2, the calculator returns your dog needs of 3,004.1638, and your dog needs (calorie mod low) of 3,478.5054, and your dog needs (calorie mod high) of 3,952.8471. Substitute your own figures and the same steps produce the same kind of answer.
Frequently Asked Questions
What do I need to work out amount of food for given the number of days?
Enter crude ash, crude fat, crude fiber, crude protein, how many days do you need food for?, dry matter, energy content in food and weight. The calculator then works through the relationship and reports amount of food for given the number of days, your dog should eat and your dog needs.
What does the dog calorie actually calculate?
It takes crude ash, crude fat, crude fiber, crude protein, how many days do you need food for?, dry matter, energy content in food and weight and converts them into amount of food for given the number of days, your dog should eat and your dog needs using the standard relationship for this problem. Each step is applied in turn, so every output is traceable back to the numbers you typed in.
How should I enter crude ash?
Use the value you actually have, in the unit shown next to the field. Enter every value in the same unit system. The calculator assumes the figures you supply are consistent, so it cannot correct a mistake that happens before the calculation starts.
Can I use this for a quick estimate as well as a precise answer?
Yes. The calculator is built for quick checks, so round your inputs to a sensible number of significant figures and the result will be just as useful. If you need more precision, keep the same method and add digits to the inputs rather than adjusting the method itself.
Does anything you type get stored?
No. The whole calculation runs inside your browser, and nothing you enter is uploaded, logged or sent anywhere.
