Royal Canin Medium Light Weight Care review

43.7/100Average
DryAdultSenior

A diet food that behaves like one, sitting in our Average band. Fibre is pushed up, fat held down and protein kept high at 29.3% of dry matter, so the weight that comes off is fat and not muscle. The score is a judgement on the ingredients list, not on whether it works.

Our view

Likely to suit

  • Medium breed dogs heavier than they ought to be
  • Dogs that beg between meals, since fibre at 12.8% of dry matter keeps them feeling fed
  • Muscle protected while the fat comes off
  • Joints under strain from extra weight: glucosamine and chondroitin sources are both on the list

Worth watching

  • Cellulose powder and vegetable fibres carry much of the bulk, fillers by design
  • Fish oil and hydrolysed crustaceans rule out dogs kept off fish or shellfish
  • Maize, wheat, barley and maize gluten crowd the upper list

The score, in context
  1. Royal Canin Medium Light Weight Care 43.7

All one Average. Typical dry food: Good.

The score reads the long, generic ingredients list; the analysis shows a properly built weight recipe, and those two pull in different directions.

What's in it
  • Dehydrated poultry proteinA family name with no bird behind it.
  • Vegetable fibresSecond on the list, which tells you what kind of food this is.
  • Maize, wheat, barley, maize glutenThe plants carry a lot of the load.
  • Hydrolysed animal proteins, maize flour, animal fats, rice
  • Beet pulp, cellulose powderCellulose is purified plant fibre, all but indigestible. A filler by design: it fills the bowl without calories.
  • Vegetable protein isolate, yeasts and parts thereofThe isolate helps the protein figure along.
  • Fish oil, soya oilFish oil carries the omega 3s.
  • Minerals, FOS, psyllium husks and seeds, hydrolysed yeast
  • Hydrolysed crustaceans, hydrolysed cartilageSources of glucosamine and chondroitin, with no dose given.
  • Marigold extractLutein.

A complete panel, with L-carnitine at 200 mg per kilo to help move fat to where it is burned; calcium is not declared.

Fish oil and hydrolysed crustaceans: not for a dog kept off fish or shellfish.

The daily figure is a maintenance estimate; a weight-loss ration is smaller, so treat it as an upper marker.

Middle of the market for a dry food, more than the ingredients reading alone earns.
