Hill's Science Plan Perfect Weight & Active Mobility Small & Mini Dry Dog Food Chicken review

56.7/100Good
DryAdultSenior

The little dog version of a slimming kibble, and it sits in our Good band. Fibre does the work here: at 13.3% it lets a small ration fill a small stomach. On a terrier one extra kilo tells the same story as five on a labrador, so that matters. Both joint ingredients come from sources the label names.

Our view

Likely to suit

  • Small and mini adults who have rounded out
  • An ageing small dog, as the label runs through the senior years too
  • Little dogs whose back legs have begun to complain. Pork cartilage supplies chondroitin and crustacean shell the glucosamine
  • Owners who want the food to do the filling, with energy at 321 kcal per 100g against a median of 357
  • Dogs on a short leash for treats. A lean recipe leaves a little room for them

Worth watching

  • Maize gluten meal third on the list, plant protein that lifts the printed figure
  • Wheat second, and fish oil at 1.9%, so neither a cereal-free nor a fish free bowl
  • Glucosamine from crustacean shells, which matters for a dog that reacts to shellfish

The score, in context
  1. Hill's Science Plan Perfect Weight & Active Mobility Small & Mini Dry Dog Food Chicken 56.7

All one Good. Typical dry food: Good.

A genuinely lean analysis and an ordinary ingredient list cancel each other out, which is a perfectly good place for a slimming food to land.

What's in it
  • Chicken and turkey meal13%Chicken pinned at 8%. Meal is dried before it goes in, so the figure holds through to the bowl.
  • Wheat
  • Maize gluten mealConcentrated plant protein that lifts the printed figure without more meat. The one to watch on a dog whose skin flares at every change.
  • Pea bran meal, maize
  • DigestThe flavour layer. No animal named.
  • Dried tomato pomace, cellulose, dried beet pulpThe fibre load. Cellulose is a purified powder, and it is what lets a smaller ration satisfy.
  • Flaxseed, coconut oil, vegetable oilVegetable oil unnamed.
  • Fish oil1.9%Omega 3.
  • Minerals, animal fat, dried carrotsAnimal fat names no animal.
  • Pork cartilage, crustacean shell hydrolysateChondroitin and glucosamine. No dose printed, so read them as everyday support.

A fully declared mineral panel: zinc at 126 mg, iron at 72 mg, copper at 7.1 mg and iodine at 1.8 mg per kilogram.

Glucosamine from crustacean shell: check before feeding a dog that reacts to shellfish.

Named ingredients

Chicken and turkey meal (chicken 8%; total poultry 13%), wheat, maize gluten meal, pea bran meal, maize, digest, dried tomato pomace, cellulose, dried beet pulp, flaxseed, coconut oil, vegetable oil, fish oil (1.9%), minerals, animal fat, dried carrots, pork cartilage (source of chondroitin sulphate), crustacean shell hydrolysate (source of glucosamine).
Against the range

One recipe. Chicken and turkey meal opens the list at 13% total poultry, with wheat and maize gluten meal close behind. Fibre is pushed to 13.3% as fed from pea bran, tomato pomace, beet pulp and cellulose, and the joint support comes from pork cartilage and crustacean shell.
