Endurance Plus Dry Dog Food, 33-lb bag
Graded by The Sniff System
American Natural Premium Endurance Plus Dry Dog Food is a dry formula built around chicken and dried egg.
This food offers good protein quality, with chicken meal providing solid amino acid coverage. It also includes quality carbohydrate sources that provide fermentable fiber. The formula benefits from diverse protein sources like dried egg, pork meat meal, chicken liver, and fish meal.
The main thing to watch out for is the absence of an AAFCO statement. This means the nutritional completeness of the food is unverified, which is a significant concern for a commercial dog food.
Good fit for owners looking for a formula with diverse protein and quality carbs. Less ideal if you require verified nutritional completeness for your dog.
Summary written by The Sniff System from the data above. Same rubric, same drivers, expressed in English.
Strong fit for active large sporting breeds like Golden Retrievers, Labrador Retrievers, and Irish Setters navigating diet-associated DCM concerns. Chicken meal anchors position 1, with zero pulses in the top 15, plus chicken liver at position 8 (a natural taurine precursor) and fish meal at position 9. In its 2022 update on diet-associated DCM, the FDA identified Golden Retrievers as the most reported breed, with 121 cases out of 1,382 total canine reports (8.8%) received between January 1, 2014, and November 1, 2022 (FDA, 2022) .

Sniff scored this formula 59/100, landing in C-tier (acceptable-with-notes). The biggest contributor was protein quality (+17 points): Reasonable protein quality. chicken meal delivers solid amino acid coverage. A hard cap of 59 also applied because the AAFCO nutritional adequacy statement isn't disclosed on the retailer page (so our methodology can't verify the formula meets adult, growth, or all-life-stages standards). If the brand publishing the AAFCO statement were on the label, the cap would lift and this formula could clear the B-band threshold (60).

- 2grainpearled barley
Barley with the outer hull removed. Easy to digest, steady carb release.
Position 2: major carbohydrate source.
- 3grainoatmeal
Gentle on the stomach. Slow-release carbs and soluble fiber that supports stool quality.
Position 3: major carbohydrate source.

Whole eggs. The highest-quality protein on any ingredient label, by amino acid score.
Position 5: significant protein contributor. Adds amino-acid diversity to the top of the deck.

- 8protein animalchicken liver
Organ meat. Dense in protein, iron, vitamin A, and the B vitamins. Among the most nutrient-rich ingredients a dog can eat.
Position 8. Functional organ inclusion. Adds amino acids and micronutrients even at smaller weight.

Concentrated fish protein, usually whitefish, herring, or mackerel. Strong amino acid profile. See why →
Position 9: supporting protein. Modest contribution to total protein weight.
