Hill's Science Plan Hypoallergenic Small & Mini Adult Dog Food with Salmon review

42.9/100Average
DryAdult

A sensible thing to try for a small dog whose skin or stomach has been arguing with poultry. Salmon meal at 9% is the only named animal, and dried potatoes at 21%, potato starch and dried peas stand in for grain. It sits in our Average band because of that starch, and no caution comes with it.

Our view

Likely to suit

  • Small and toy adults who have not got on with poultry
  • Owners who want cereal out of the bowl entirely
  • Flaky skin. Salmon meal and flaxseed bring omega 3 in the form skin uses directly
  • Anyone who likes the mineral doses printed, zinc at 90.3 mg per kilo among them
  • Little dogs that need a short list with fewer places for a trigger to hide

Worth watching

  • Animal fat and digest with no species named, so the list is narrow but not closed
  • A big plant side: estimated carbohydrate at 55.5% of dry matter against 46.2% for a typical adult dry food
  • Fish is the only animal protein, which matters for a dog kept away from it

The score, in context
  1. Hill's Science Plan Hypoallergenic Small & Mini Adult Dog Food with Salmon 42.9

All one Average. Typical dry food: Good.

Starch sets the score here, and on the narrow brief of fewer things to react to the recipe holds up better than the number suggests.

What's in it
  • Dried potatoes21%Opens the list and does the job cereal does in most kibbles.
  • Potato starchWhat lets a grain-free biscuit keep its shape.
  • Dried peas
  • Salmon meal9%The only named animal. Dried fish meal is concentrated, so it gives more than the same figure as fresh fish would.
  • Pea proteinLifts the protein total, so the 21.6% in dry matter is shared between plant and fish.
  • Animal fat, digestNeither names its species. The digest is there for taste.
  • Vegetable oil, minerals
  • Dried beet pulp, flaxseedThe two small entries doing real work: beet pulp for the gut, flaxseed for the coat.
  • Dried carrots, tomato pomace, citrus pulp, spinach powderSmall antioxidant additions that make the label look longer than the recipe is.

Zinc at 90.3 mg, iron at 51.5 mg, manganese at 5.3 mg, copper at 5.1 mg, iodine at 1.3 mg and selenium at 0.1 mg per kilo, all printed in full.

Protein is 19.9% as fed, and part of it comes from pea protein.

Dried potatoes (21%), potato starch, dried peas, salmon meal (9%), pea protein, animal fat, digest, vegetable oil, minerals, dried beet pulp, flaxseed, dried carrots, dried tomato pomace, dried citrus pulp, spinach powder.
Against the range

One recipe, built short on purpose: salmon meal is the only named animal, and potato and pea do the work cereal does in most kibbles. The animal fat and the digest are the two entries that keep the list from being fully closed.

The premium end for a dry food, and the price runs ahead of what the analysis shows.
