Royal Canin Medium Light Weight Care review
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

How this scores

Dog fit
Listed for medium adult and senior dogs. The ration for weight loss is smaller than maintenance, so set it from your dog's target weight and not its current one.

The score, in context
- 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.

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