The Comparison

Two Foods, One Method

The same five measures, applied to each food from its own figures.

Every food here is made by NutriSource, so the recall row cannot separate them.

Prices are the lowest per pound we found across bag sizes, from our latest checks. Stores change prices often.

Two Foods, One Method. Each row is one measure; the best figure in a row is marked.
01 NutriSource Grain-Free Heartland Select Swap Remove 02 NutriSource Element Series Open Waters Swap Remove + Add A Food + Add A Food
01 Protein, Dry Matter Higher Is Better 26-32% dm reads typical mainstream. 01 Grain-Free Heartland Select 27.8% 02 Element Series Open Waters 37.8% Best in this row
02 Carbohydrate Load, Dry Matter Lower Is Better Estimated, 6% ash assumed. Estimated, not measured. It is what is left of the guaranteed analysis once protein, fat, fiber and moisture are taken out, with ash assumed at 6%. That leftover is mostly starch but also carries sugars and the fiber a crude-fiber test misses, so read it as a close estimate rather than an exact figure. Measured as fed, the same basis as the bag. 01 Grain-Free Heartland Select 41% 37.0% as fed 02 Element Series Open Waters 32% 29.0% as fed Best in this row
03 Named Proteins In The First Five Count of named animal proteins. The count matches any named animal word in the opening five ingredients, so it also counts animal fats and flavourings as proteins. It is shown because it is one of the five measured lines, but it is too rough to call a winner on. 01 Grain-Free Heartland Select 3 of 5 02 Element Series Open Waters 4 of 5
04 Flagged Additives Level Lower Is Better Matched against the flag list. 01 Grain-Free Heartland Select None 02 Element Series Open Waters None
05 Brand Recall History Level Manufacturer, not recipe. 01 Grain-Free Heartland Select 1 None in the last 3 years 02 Element Series Open Waters 1 None in the last 3 years
Starch, As Fed Estimated, not measured. It is what is left of the guaranteed analysis once protein, fat, fiber and moisture are taken out, with ash assumed at 6%. That leftover is mostly starch but also carries sugars and the fiber a crude-fiber test misses, so read it as a close estimate rather than an exact figure. Measured as fed, the same basis as the bag. 01 Grain-Free Heartland Select 37.0% 02 Element Series Open Waters 29.0%
Kcal / Cup 01 Grain-Free Heartland Select 432 02 Element Series Open Waters 504
Price / Lb Lowest Across Bag Sizes 01 Grain-Free Heartland Select -- No price on file. 02 Element Series Open Waters $4.41 24 lb bag, Petflow
Cost / 1,000 Kcal Lower Is Cheaper To Feed What the same amount of energy costs, so a denser food is not penalized for a higher price per pound. 01 Grain-Free Heartland Select -- No price on file. 02 Element Series Open Waters $2.45
First Five Ingredients 01 Grain-Free Heartland Select Bison, Chicken, Chicken Meal, Peas, Pea Flour 02 Element Series Open Waters haddock, trout, duck, salmon, salmon meal

Add A Food

Every figure here is the food's own. Protein and carbohydrate are converted to dry matter so foods of different moisture can be set beside each other; starch is estimated from the guaranteed analysis with ash assumed at 6.0%, and the recall record belongs to the manufacturer rather than to the recipe. Two rows are printed but never marked: the named-protein count, because the detection behind it is too rough to call a winner on, and calories, because neither more nor fewer is better without knowing the dog.
