Size Health Nutrition Giant Junior Dry Dog Food, 30-lb bag
Graded by The Sniff System
Royal Canin Size Health Nutrition Giant Junior is a dry dog food formulated for growing giant breed puppies, with chicken by-product meal as its primary protein.
This formula includes quality fat sources like named chicken fat and marine oil, which provides beneficial EPA and DHA. It also features quality carbohydrate sources with fermentable fiber, and it has AAFCO feeding trial substantiation for growth.
The primary protein, chicken by-product meal, contributes to lower protein quality, meaning it delivers limited bioavailable amino acids.
Good fit for growing giant breed puppies. Less ideal if you prefer higher quality, more bioavailable protein sources.
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. At 311 kcal/cup this formula runs on the lean side. 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) .

Read why each ingredient is good or bad for dogs.
- 1protein 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 1: primary protein source. After cooking removes water, this may drop in proportional weight, but it anchors the recipe.
- 2graincorn
Whole corn is more nutritious than it gets credit for, with decent amino acids and steady carbs. The bigger concern is when corn dominates the top of the ingredient list at the expense of named meat.
Position 2: major carbohydrate source.
- 3brewers rice flour
- 4brewers rice
Broken rice kernels left over from milling, usually destined for human beer-making. Cheaper than whole or even white rice. Same carbs, less nutrition than the brown version. See why →
Position 4: supporting grain. Smaller contribution to the carb deck.
- 5protein plantwheat gluten
Concentrated wheat protein. Like other plant gluten meals, it pads the protein number on the label without contributing meat-quality amino acids.
Position 5: plant protein in the top 5. Stacked with animal protein, can inflate the crude protein number without matching the amino-acid quality of named animal sources.
- 6fatchicken fat
Despite the name, a high-quality energy source. Concentrated calories plus essential fatty acids like linoleic acid. See why →
Position 6: secondary fat. Often where marine oils sit when present alongside a primary land-animal fat.
- 7othernatural flavors
Same as natural flavor. Usually hydrolyzed liver or broth, adds palatability.
- 8dried 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 8: functional fiber for digestion or satiety.
- 9protein plantcorn gluten meal
Concentrated corn protein. Inflates the protein percent on the label without matching meat-quality amino acids.
Position 9: moderate plant-protein boost. Less likely to materially shift the protein profile.
- 10sodium aluminosilicate
Anti-caking agent that keeps powder ingredients flowing. Functional, not nutritional.
- 11monocalcium phosphate
Source of calcium and phosphorus. Standard mineral inclusion in complete dog foods.
- 12fiberpea fiber
Insoluble fiber from peas. Doesn't carry the protein-inflation concern of pea protein. Mostly there for stool quality.
Position 12. Trace inclusion. Below the level associated with the FDA's DCM-pattern concerns.
- 13vegetable oil
Unnamed plant oil. Could be soy, canola, corn, or a blend. Named oils like sunflower or canola are more transparent.
Position 13: trace fat. Below the level that materially shifts the fat profile.
- 14mineralcalcium carbonate
Source of calcium. Functional. Required in complete dog foods, especially those without bone-in meat meals.
- 15mineralpotassium chloride
Required mineral. Sometimes used as a salt substitute. Standard inclusion in complete diets.
- 16mineralsalt
Sodium chloride. Required at small doses for normal physiology. Not a quality concern in standard amounts.
- 17powdered psyllium seed husk
- 18fatfish oil
Concentrated omega-3s. The reason 'EPA' and 'DHA' get to show up on the bag.
- 19supplementtaurine
Amino acid critical for heart health. Especially important in grain-free or pulse-heavy formulas where natural taurine precursors run thin.
- 20fiberfructooligosaccharides
Prebiotic fiber, often called FOS. Feeds beneficial gut bacteria, similar in function to inulin.
- 21supplementl-lysine
Essential amino acid. Plant-protein-heavy formulas sometimes add it to round out the amino acid profile.
- 22hydrolyzed yeast
Yeast broken down with enzymes. Strong palatant plus a real source of B vitamins and amino acids.
- 23supplementcholine chloride
Essential nutrient for liver and brain function. Standard inclusion in complete dog foods.
- 24marine microalgae oil
Plant-source omega-3 from algae. Useful especially in vegetarian or limited-fish formulas.
- 25supplementdl-methionine
Essential amino acid. Often added when plant proteins dominate, since methionine is naturally lower in pulses than meat.
