Graded by The Sniff System
Iams Advanced Health Adult Healthy Digestion is a dry food for adult dogs, featuring chicken and chicken by-product meal as its main protein sources.
This formula offers good protein quality, with chicken providing solid amino acid coverage for adult dogs. It also includes quality carbohydrate sources with fermentable fiber, which can support healthy digestion. Dried egg product adds diverse, highly bioavailable protein to the mix.
Nothing concerning in the deck.
Good fit for adult dogs of any size. Nothing serious working against it.
Summary written by The Sniff System from the data above. Same rubric, same drivers, expressed in English.
Good fit for lower-energy small companion breeds, including the French Bulldog, navigating a sensitive stomach. Chicken leads at position 1, with dried plain beet pulp (prebiotic fiber) at position 6 and dried bacillus subtilis fermentation product (probiotic culture) on the deck. Frenchies have notoriously sensitive GI tracts plus a tendency toward obesity given their low activity needs. Limited-ingredient formulas with moderate calorie density tend to fit them well.

Solid grade. 71/100 (B) reflects the structural fit of this formula against The Sniff System's eight scoring components. Protein quality did the heavy lifting (+17 points): Reasonable protein quality. chicken delivers solid amino acid coverage. The supporting beat: carbohydrate quality (+16 points). Quality carbohydrate sources with fermentable fiber. What's keeping it out of A-tier: protein quality (17 of 27 possible). Full protein quality requires named-species named-cut proteins in the top of the deck (e.g., "deboned chicken" rather than "chicken meal" or "poultry meal").
Reasonable protein quality. chicken delivers solid amino acid coverage.
Quality carbohydrate sources with fermentable fiber.
Includes egg, named fish, or organ meat for diverse high-bioavailability protein.

Read why each ingredient is good or bad for dogs.
- 1protein animalchicken
Real meat. Primary protein source, with the amino acid profile dogs actually evolved to eat.
Position 1: primary protein source. After cooking removes water, this may drop in proportional weight, but it anchors the recipe.
- 2protein animalchicken by-product meal
Ground organs, bone, and tissue. Nutritionally dense, especially the liver and gizzard fractions. Named species ('chicken') is what matters. Generic 'poultry by-product meal' is the one to worry about. See why →
Position 2: co-primary protein. Two named animal proteins in the top 2 is a strong protein build.
- 3ground whole grain corn
Whole corn with the kernel intact. Decent fiber and B vitamins, though it can crowd out meat in cheaper recipes.
Position 3: major carbohydrate source.
- 4ground whole grain sorghum
Position 4: supporting grain. Smaller contribution to the carb deck.
- 5grainbarley
Whole grain with a low glycemic profile and some soluble fiber. Easy on blood sugar.
Position 5: supporting grain. Smaller contribution to the carb deck.
- 6dried plain beet pulp
Beet fiber, with the sugar removed. Long unfairly maligned. It's a real soluble fiber that supports stool quality. See why →
Position 6: functional fiber for digestion or satiety.
- 7othernatural flavor
Legal term for animal-derived flavoring, usually hydrolyzed liver or broth. Adds taste, says nothing about quality.
- 8dried egg product
Whole eggs with the water removed. Same nutritional value as fresh eggs, just shelf-stable.
Position 8: supporting protein. Modest contribution to total protein weight.
- 9fiberfructooligosaccharides
Prebiotic fiber, often called FOS. Feeds beneficial gut bacteria, similar in function to inulin.
Position 9: functional fiber for digestion or satiety.
- 10fatchicken fat
Despite the name, a high-quality energy source. Concentrated calories plus essential fatty acids like linoleic acid. See why →
Position 10: trace fat. Below the level that materially shifts the fat profile.
- 11fatflaxseed
Plant source of omega-3. Helpful for skin and coat, though dogs absorb omega-3 from fish more efficiently.
Position 11: trace fat. Below the level that materially shifts the fat profile.
- 12caramel color
Artificial coloring made by heating sugars. Cosmetic. Some forms contain trace 4-MEI, a compound the IARC lists as possibly carcinogenic.
- 13mineralpotassium chloride
Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.
- 14probioticdried bacillus subtilis fermentation product
Probiotic culture. Functional regardless of position if viable through extrusion.
- 15vegetablecarrots
Real vegetable. Fiber, beta-carotene, and a small amount of antioxidant value.
Position 15: garnish-level inclusion. Marketing-prominent but minimal nutritional impact at this position.
- 16supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 17supplementdl-methionine
Essential amino acid. Often added when plant proteins dominate, since methionine is naturally lower in pulses than meat.
- 18mineralcalcium carbonate
Source of calcium. Functional. Required in complete dog foods, especially those without bone-in meat meals.
- 19mineralferrous sulfate
Inorganic iron. Standard mineral source. Iron proteinate is the gentler, better-absorbed premium form.
- 20zinc oxide
Inorganic zinc. Cheapest mineral form on the market. Functional but less bioavailable than chelated alternatives.
- 21mineralsodium selenite Flagged
Inorganic selenium. Effective at AAFCO levels, no documented safety concern in dogs despite what some pet food blogs claim. Selenium yeast is a marginal upgrade, not a necessity. See why →
- 22mineralmanganese sulfate
Inorganic manganese. Functional but less well-absorbed than the chelated proteinate form.
- 23mineralcopper sulfate
Inorganic copper. Standard, effective at small doses. Premium formulas tend to use copper proteinate instead.
- 24mineralpotassium iodide
Source of iodine, an essential trace mineral for thyroid function. Required for AAFCO-complete formulas.
- 25manganous oxide
Inorganic manganese. Functional, cheaper than chelated forms, less efficiently absorbed.
