Hill's Science Diet Adult Perfect Digestion Salmon & Brown Rice Recipe Dog Food | Hill's Science Diet

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, I would recommend it for adult dogs whose stool quality swings easily, not for a strict salmon-led diet.

Logic-based verdict

This food can stay in comparison, but ingredient quality still needs a more conservative read.

There is enough public data to keep this food in comparison, but the top ingredient structure does not support a stronger positive claim yet.

Nutritional strengths

  • 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.

What still needs work

  • Processed plant protein appears after the top 3, so some protein support is still built into the label number.
  • Fish protein is still the first ingredient, but plant-protein boosters high in the recipe make it a more cautious alternative-protein candidate.
  • Public data is usable, but not at the highest-trust tier.

Ingredient Analysis Comments

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

Why processed plant proteins are reviewed cautiously

Ingredient lists are ordered by input weight, not protein contribution. Fresh meat 100g and Soybean Meal 50g can both contribute about 20g of protein, and Pea Protein can deliver a similar amount at around 30g. So these ingredients can materially lift crude protein even outside the top three. The review treats processed plant-protein boosters cautiously because they can weaken the animal-protein-centered profile most guardians expect from a high-protein food.

Why did the base review land here?

Ingredient qualityNutrient disclosure levelManufacturing & trust

This review score combines ingredient composition, nutrient disclosure, manufacturing trust, and core nutrient caution signals.

Nutrient disclosure

Partial disclosure

Core guaranteed analysis is usable, but deeper rows still need a more cautious read.

Safety verification

No fails

No major red flag jumps out first, though undisclosed rows still define the limits of this safety read.

Public data trust (ETF)

C1 tier

There is a usable disclosure baseline, but the public record is still fairly thin.

Final word

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