Many are using Pet Diet Designer to track nutrient intake for their dog or cat. While there isn’t really anything quite like PDD (especially with the new RMB analysis coming out in 2018 EDIT: THEY DID NOT COME OUT WITH NEW PRORGRAM), Cronometer is a great free tool for humans and pets. You should already know about basic canine or feline nutrition and how to get the NRC values (or values of choosing) before using this tutorial. This tutorial is more of a tech tutorial- and not meant to impart any nutritional understanding. Please handle nutrition with great care.

This will help you visualize your nutrition goals for your pet- but will still require other work as it does not automatically display ratios in the diet- such as EPA to DHA, calcium to phosphorus, and the free version will not save recipes like we do with pet diet designer. However, it does save the daily diary, which you can copy. You can also print the recipes that you like.

Before proceeding, you can also use cronometer to just spit out the values of a recipe without having to do all the alternations below. However, if you want cronometer “nutrition bars” and most of the user interface to reflect NRC (or whatever) values, proceed below.


Always check the nutrient values when entering a food as some foods have missing values. If something seems off, investigate it. Some foods are crowdsourced- so use caution! Compare nutrient values with nutrition data.


Again, you should already know where and how to use NRC numbers specific to your dog or cat (or whatever nutritional numbers you are using.) These are the numbers that you will be using for this tutorial. One example would be the nutrient numbers from the “Dog and Cat Nutrient Requirement” pages.  

You should already have been studying nutrition. Do not dive into this as your first step. At the very minimum, do the raw feeding road map. Fall course is better.

You will of course want to make an account. We will be changing all the of the values- so don’t fret about the weight age etc.


Once signed in, click on the profile tab and then scroll down to nutritional targets.


Select custum on the calories. You will want to select custom, and then enter your calorie goal for minimum and maximum. I used my dog’s caloric goal for the minimum and maximum. To change the numbers, you click directly on them. A box will pop up allowing you to change the nutrient value.


The rest is pretty similiar. Select custom and change the visibility based on your own preference. (Some may choose to deselect nutrients not required, some may leave them be or prefer to see everything). An example set up would be to set the RA numbers as the minimums and then set the UL numbers for applicable maximums, or however you choose. There is much room for customization. 


You can also do everything in step three directly on the main diary page. Simply select the macro or micro nutrient values and fill out the box that pops up. Make sure to select use custom instead of RDA.


You may have a supplement or wishing to enter in bone nutrient data that is not already on the listed foods. Select the foods tab. Then select “create new food” which is on the left sidebar as a button.  Proceed to fill out the custom food by directly interacting with the form seen to the right.

Save your food.
