Hill's Science Plan Hypoallergenic Large Breed Adult Dog Food with Salmon review

43.8/100Average
DryAdult

A short-list kibble for large dogs that sits in our Average band: one named fish, no grain and potato doing most of the work. Salmon meal is declared at 9%. For a big dog who has never got on with the usual meats it is a straightforward food to try.

Our view

Likely to suit

  • Large adults out of luck with the common meats. Salmon is the one animal named
  • Grain-free homes, as dried potatoes and potato starch carry the recipe
  • Skin and coat that want marine omega 3, from salmon meal and flaxseed
  • A fish-based food that still feeds like an ordinary kibble

Worth watching

  • Animal fat and digest name no species, so a strict elimination trial cannot rest on this alone
  • Carbohydrate estimated at 55.5% of dry matter, against 46.2% for a typical adult dry food
  • Pea protein means part of the declared 19.9% protein comes from a plant

The score, in context
  1. Hill's Science Plan Hypoallergenic Large Breed Adult Dog Food with Salmon 43.8

All one Average. Typical dry food: Good.

The reading reflects the starch share, with potato and pea ahead of the salmon; on its narrower brief of a short list it does something genuinely useful.

What's in it
  • Dried potatoes21%Top of the list. Largely starch.
  • Potato starchThe binder that lets a grain-free biscuit hold together.
  • Dried peasFibre and some minerals with the starch.
  • Salmon meal9%The only animal named. Water free, so it goes further than fresh salmon would.
  • Pea proteinPlant protein in the total.
  • Animal fat, digestNeither has a species attached. The detail to raise with your vet before an exclusion diet.
  • Vegetable oilUnnamed.
  • Minerals, dried beet pulp
  • FlaxseedPlant omega 3 beside the fish.
  • Tomato pomace, citrus pulp, spinach powder, dried carrotsSmall antioxidant touches.

Salmon runs right through the recipe, so not one for a dog avoiding fish.

Pricing & size

Cost per day, 15kg dog
£0.99

A large breed adult eats well above the 15kg reference, so the daily cost rises with the portion.

Middle of the market for a dry food, and the price runs a little ahead of the analysis.
