cdubau, Fromm’s also has a new kibble http://frommfamily.com/products/gold/dog/dry/#gold-coast-weight-management

It looks to be similar in protein, fat, etc. but whitefish and salmon meal first 2 ingredients.

Here’s some info on calculating carbs from Dr. Mike:

How to Estimate the Carbohydrate
Content of Any Dog Food

So, if knowing the carb content is important to you — and it should be — here’s a quick and easy way to estimate the amount of carbohydrates in any dog food — yourself.

Basically, all foods contain the same four major nutrients — known as macronutrients:

Proteins
Fats
Carbohydrates
Moisture (water)

In addition, all foods also contain ash — the non-combustible mineral residue remaining after burning away all the protein, fat and carbs.

Ash content can vary — but typically measures about five to eight percent for most dog foods1 .

So, for consistency, we routinely use 8 percent as a benchmark for this important variable (ash) throughout this site.

Making the Calculation

When making this calculation, it’s important to keep in mind the following scientific principle:

Protein + fat + ash + carbohydrate + water must always equal 100 percent of the total pre-cooking weight of any dog food.

So, you can use simple math to reveal the missing amount on any other variable — which in this case of a pet food would be the carbohydrates.

Simply start with 100 percent and subtract the percentage for each of the known macronurients.

By the way, you can ignore the fiber content because fiber is a type of carbohydrate and would be automatically included in your carbohydrate calculation.

Here’s an Example

Say a particular dog food contains 26% protein, 14% fat and 10% water. How much carbohydrate should we expect to find in that product?

To estimate the amount of carbohydrate present in this example, simply start with a total of 100 percent. Then subtract the protein, fat and moisture percentages.

And of course, don’t forget to allow for an ash content of about 8 percent, too.

So, your math would look like this:

Carbohydrates = 100% – 26% – 14% – 10% – 8% = 42%

In other words, if you subtract all the “known” nutrients, you’d be left with the missing variable — carbohydrates — which in our example would be about 42 percent.
