Editor ingredient insight

Hill’s Perfect Digestion Salmon and Brown Rice lists salmon first, but cracked pearled barley, brown rice, brewers rice, corn protein meal, and chicken meal follow, so I would not call it a clean fish-heavy food.

With 25% protein, 15% fat, beet pulp, and citrus pulp, It is worth considering for adult dogs whose stool quality swings easily, not for a strict salmon-led diet.

Ingredient #1Top

Salmon

Salmon is a named fresh meat ingredient. The animal source is clearly identified. It reads as an top-tier protein source.

Ingredient #2Mid

Cracked Pearled Barley

Cracked Pearled Barley is disclosed, but its role is not explicit enough to count as a strong quality signal. It reads as an mid-tier carb source.

Ingredient #3Upper

Brown Rice

Brown Rice is a whole or coarse grain ingredient. It usually plays more of a carbohydrate and fiber role than a core protein role. It reads as an upper-tier carb and fiber source.

03. CHOOSING FOR YOUR DOG

What to consider before feeding

Salmon supply animal protein at the start of the ingredient list. Cracked Pearled Barley, Brown Rice supply carbohydrate energy. The recipe combines animal protein sources with carbohydrate sources.

Corn Protein Meal, Pea Protein supplement plant protein further down the list, after the first three ingredients. The crude-protein figure includes both animal and plant contributions. Chicken Fat add fat and energy; fat content is a separate choice criterion from the protein sources.

Across the registered ingredients, multiple protein sources appear, including salmon, chicken. If a protein must be excluded, any of these sources can change the decision; the first ingredient alone does not make this a single-protein diet.

What works well in this food

  • The first ingredient is a species-named fresh meat.
  • Crude protein does not drop into a clearly low band.
  • Top ingredients do not show a prominent FDA-investigated non-hereditary DCM ingredient profile.

Check before feeding

  • Processed plant protein appears after the top 3, so some protein support is still built into the label number.
  • The first ingredient is a species-named fresh meat, but grains follow immediately after it, so the recipe reads more mixed than meat-led.
  • Public data is usable, but not at the highest-trust tier.

When this food fits your dog

Among foods made the same way, protein is typical, fat is typical, and calorie density is typical. Calorie density alone does not separate this into an active-dog or weight-management food. Consider protein exclusions and fat, then set portions for the dog’s weight and activity.

Consider it first when

  • Public-data-first comparison
  • Baseline shortlist building
  • Conservative first-pass screening

Choose another food first when

  • You want a stronger ingredient-quality story first
  • You need dog-specific fit instead of public-review screening

Plant-protein concentration remains the clearest trade-off here.

Final word

Interpret this for my dog

The food-first public score is only the starting point. Once your dog’s activity, weight goals, life stage, and health status are applied, the recommendation order and interpretation can change.

There is enough here to keep the food in comparison, but not enough to stop comparing yet.
