Proactive Health Large Breed Adult with Real Chicken Dry Dog Food, 30-lb bag
Graded by The Sniff System
Iams Proactive Health Large Breed Adult with Real Chicken Dry Dog Food is a dry formula for adult large breed dogs, featuring chicken as a primary protein.
This formula uses quality carbohydrate sources that provide fermentable fiber, which is good for gut health. It also includes dried egg product for diverse, highly digestible protein. The food has been substantiated for adult maintenance through AAFCO feeding trials.
Nothing concerning in the deck.
Good fit for adult large breed dogs. Nothing serious working against it.
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 Labrador Retrievers, Golden Retrievers, and English Setters navigating weight management. Working in its favor: explicitly formulated for large-breed dogs. At 354 kcal/cup this formula runs on the moderate side, with crude fiber at 5% (above the catalog median, supports satiety). The landmark 14-year Purina Lifespan Study on 48 Labrador Retrievers demonstrated that dogs fed 25% fewer calories lived a median of 1.8 years longer and delayed the onset of chronic diseases. The 2014 AAHA Weight Management Guidelines define overweight as a Body Condition Score (BCS) of 6-7 on a 9-point scale. A score of 8 or 9 indicates obesity, representing 20-30% and >30% above ideal body weight, respectively (Brooks et al., 2014) .

Solid grade. 71/100 (B) reflects the structural fit of this formula against The Sniff System's eight scoring components. Carbohydrate quality did the heavy lifting (+15 points): Quality carbohydrate sources with fermentable fiber. The supporting beat: AAFCO compliance (+8 points). AAFCO feeding trial substantiation for adult maintenance. What's keeping it out of A-tier: protein quality (14 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").

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.
- 2grainbarley
Whole grain with a low glycemic profile and some soluble fiber. Easy on blood sugar.
Position 2: major carbohydrate source.
- 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.
- 4protein 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 4: significant protein contributor. Adds amino-acid diversity to the top of the deck.
- 5ground whole grain sorghum
Position 5: supporting grain. Smaller contribution to the carb deck.
- 6protein plantsoybean meal
Concentrated soy protein. Cheap plant protein that pads the label number, common in budget formulas.
Position 6: moderate plant-protein boost. Less likely to materially shift the protein profile.
- 7dried 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 7: functional fiber for digestion or satiety.
- 8othernatural flavor
Legal term for animal-derived flavoring, usually hydrolyzed liver or broth. Adds taste, says nothing about quality.
- 9brewers dried yeast
Yeast left over from brewing. Rich in B vitamins and amino acids. A traditional and well-tolerated inclusion.
- 10dried egg product
Whole eggs with the water removed. Same nutritional value as fresh eggs, just shelf-stable.
Position 10: supporting protein. Modest contribution to total protein weight.
- 11fatchicken fat
Despite the name, a high-quality energy source. Concentrated calories plus essential fatty acids like linoleic acid. See why →
Position 11: trace fat. Below the level that materially shifts the fat profile.
- 12fatflaxseed
Plant source of omega-3. Helpful for skin and coat, though dogs absorb omega-3 from fish more efficiently.
Position 12: trace fat. Below the level that materially shifts the fat profile.
- 13legumepeas
Cheap protein bulk. Fine in small amounts, but when peas stack with lentils and chickpeas in the top ingredients, it's the pattern the FDA flagged in its heart-disease investigation. See why →
Position 13. Trace inclusion. Below the level associated with the FDA's DCM-pattern concerns.
- 14caramel color
Artificial coloring made by heating sugars. Cosmetic. Some forms contain trace 4-MEI, a compound the IARC lists as possibly carcinogenic.
- 15supplementdl-methionine
Essential amino acid. Often added when plant proteins dominate, since methionine is naturally lower in pulses than meat.
- 16mineralpotassium chloride
Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.
- 17fiberfructooligosaccharides
Prebiotic fiber, often called FOS. Feeds beneficial gut bacteria, similar in function to inulin.
- 18supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 19mineraldicalcium phosphate
Calcium and phosphorus combined. Required source of both minerals, especially in formulas without much bone content.
- 20vegetablecarrots
Real vegetable. Fiber, beta-carotene, and a small amount of antioxidant value.
- 21mixed tocopherol
- 22preservative naturalcitric acid
Natural antioxidant preservative. Helps keep fats from going rancid.
- 23mineralferrous sulfate
Inorganic iron. Standard mineral source. Iron proteinate is the gentler, better-absorbed premium form.
- 24zinc oxide
Inorganic zinc. Cheapest mineral form on the market. Functional but less bioavailable than chelated alternatives.
- 25mineralsodium 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 →
