Hill's

Hill's d/d Potato & Salmon Recipe Dry Dog Food | Hill's Prescription Diet

Editor ingredient insight

Hill’s d/d Potato & Salmon starts with potatoes, potato starch, and salmon, with lower protein and omega-3 disclosed. I would use it for veterinarian-guided salmon-and-potato feeding, not for high-salmon-density expectations.

Logic-based verdict

This is a prescription diet for allergy/skin care, so purpose fit comes before standard star ranking.

This is a prescription-diet candidate for allergy/skin care. Read purpose fit and veterinary guidance before treating it as a standard star-ranked food.

Nutritional strengths

  • Omega-3, Omega-6, EPA+DHA, Vitamin E are disclosed, which helps compare skin-barrier and coat-support markers.
  • Top ingredients do not show a prominent FDA-investigated non-hereditary DCM ingredient profile.

What still needs work

  • Refined carbohydrates lose fiber, vitamins, and minerals during processing, and mainly act as starch and energy sources. Because of that, our engine reads ingredient quality more conservatively than it would with whole grains.
  • Processed plant protein appears after the top 3, so some protein support is still built into the label number.
  • Public data is usable, but not at the highest-trust tier.

Ingredient Analysis Comments

  • •Potatoes is a starchy tuber ingredient. It is not a grain, but it still reads mainly as a starch and energy source. It reads as an mid-tier carb source.
  • •Potato Starch is a refined carbohydrate source. It usually reads as a starch and energy source rather than a protein driver. It reads as an mid-tier carb source.
  • •Salmon is a named fresh meat ingredient. The animal source is clearly identified. It reads as an top-tier protein 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

Treat this review as an early screen. If the food stays interesting, verify it again with your dog-specific context before acting.
