Hill's Science Plan Perfect Weight Small & Mini Adult Dog Food with Chicken review

43.8/100Average
DryAdultSenior

A slimming kibble sized for a small dog's mouth, and the label is upfront about how it gets there. Purified fibre fills the bowl so the ration stays visible while the energy drops. It sits in our Average band, because it is designed to dilute.

Our view

Likely to suit

  • A small dog whose collar has been letting out a notch at a time
  • Small and mini adults who need fewer calories without their dinners disappearing
  • Little jaws. The kibble is made for them
  • An older small dog, as adults and seniors share the bag
  • Dogs fine on chicken and turkey

Worth watching

  • Wheat first on the list, the one thing it cannot work around for a wheat-sensitive dog
  • Chicken at 9% within 14% poultry, so maize protein meal carries much of the protein
  • Animal fat and digest with no species, and fibre high enough that some dogs take a week or two to settle

The score, in context
  1. Hill's Science Plan Perfect Weight Small & Mini Adult Dog Food with Chicken 43.8

All one Average. Typical dry food: Good.

Take the calories out of a kibble and cereal and fibre fill the space, so the band says more about the arithmetic of slimming than about quality control.

What's in it
  • WheatAn inexpensive, low-fat base. Also among the cereals most often behind an itchy dog.
  • Maize protein mealConcentrated plant protein doing much of the lifting.
  • Chicken and turkey mealchicken 9%, poultry 14%Dried and concentrated, though plainly not the main event.
  • Pea bran meal, maize
  • DigestThe flavour coating that gets a low-calorie kibble eaten. No species named.
  • Dried tomato pomace
  • CellulosePurified fibre with next to no energy. It fills the bowl without feeding the dog.
  • FlaxseedPlant omega 3.
  • Animal fat, coconut oilThe animal fat names no species.
  • Dried beet pulp, minerals, dried carrots

Every trace mineral has a printed dose, zinc at 132mg a kilo first, with a natural antioxidant.

Almost every dog on this bag is far smaller than 15kg and on a reduced ration, so the real daily cost is a fraction of the guide.

Middle of the market for a dry food, and you pay more than the analysis alone would justify.
