How to Calculate Carbohydrates in Dry Dog Food

How to Calculate Carbohydrates in Dry Dog Food

Just like we like to check out the nutritional facts on the back of the foods we eat, there are key nutritional facts on the back of pet food packaging that are worth nothing. However, the cart looks a little different than what we are familiar with on human foods. The Food and Drug Administration currently only requires just four macronutrients to be displayed on the back label: protein, fat, fiber, and moisture. In addition, all foods also contain ash - the noncombustible mineral residue remaining after burning away protein, fat, and carbs.

If carbohydrate content is important to one of your customers, you can quickly calculate carbs by keeping this scientific principle in mind: Protein + fat + ash + carbohydrate + water must always equal 100% of the total pre-cooking weight of any dog food.

You can use simple math to calculate the missing amount on any of the variables. To calculate carbohydrates in food, start with 100 and subtract the percentage for each of the known macronutrients. Ash content can vary between 5% and 8%, so we will use 8% as the benchmark for calculations.

If a dog food contains 26% protein, 14% fat, 10% moisture, and you include the standard 8% ash content, this would mean that the food contains 42% carbohydrates.

If you are concerned about carbohydrate content in your pet's food, we would be happy to help you find the perfect food for your furry friend.
