Royal Canin Maxi Light Weight Care review

44.1/100Average
DryAdultSenior

A slimming food for big dogs that does the job it is bought for. Crude fibre is declared at 11.4%, energy comes in at 320 kcal per 100g and L-carnitine is dosed at 200 mg per kilo. It lands in our Average band because of how the list is written, and the diet's design is not the problem.

Our view

Likely to suit

  • A big dog whose waistline has gone missing
  • Large and giant adults who need to lose weight and still want a full bowl. Crude fibre is 11.4%
  • Neutered or slowing dogs whose appetite has not slowed with them
  • Keeping protein up on a cut ration: 27.0% declared against fat of 11.0%
  • Seniors too, with glucosamine and chondroitin listed for joints that have carried the weight

Worth watching

  • Cellulose powder as a fibre source. It adds bulk and almost no energy
  • Poultry, animal fats and hydrolysed animal proteins with no species named
  • Maize, barley, wheat and two glutens on the list, plus fish oil, so it is not fish free
  • Bigger stools while a dog adjusts to fibre this high

The score, in context
  1. Royal Canin Maxi Light Weight Care 44.1

All one Average. Typical dry food: Good.

The weight-loss design is sound; the unnamed bird, unnamed fats and gluten proteins on the list are what hold the score back.

What's in it
  • Dehydrated poultry proteinsFirst on the list. Poultry is a catch-all word that could be chicken, turkey, duck or goose.
  • Vegetable fibresSecond place, filling the bowl with material that carries very little energy.
  • Maize, barley, maize flour
  • Maize gluten, wheat glutenPlant protein lifting the declared total. Royal Canin marks the wheat gluten as highly digestible.
  • Hydrolysed animal proteins, wheat, animal fatsNo species named for the proteins or the fats.
  • Beet pulp, cellulose powderCellulose is close to indigestible, which is why a light food uses it.
  • Fish oilThe omega 3 source.
  • Minerals, yeasts products, fructo-oligosaccharides, psyllium husks and seedsPsyllium swells with water; the FOS feed gut bacteria.
  • Soya oil, marigold meal
  • Glucosamine from fermentation, hydrolysed cartilageThe joint pair, with no dose given.

A complete mineral and vitamin panel dosed line by line, with zinc at 133 mg and selenium at 0.09 mg per kilo, plus L-carnitine at 200 mg for fat burning.

Clinoptilolite is added at 5 g per kilo as a processing aid.

Named ingredients

Dehydrated poultry proteins, vegetable fibres, maize, barley, maize flour, maize gluten, wheat gluten*, hydrolysed animal proteins, wheat, animal fats, beet pulp, cellulose powder, fish oil, minerals, yeasts products, fructo-oligosaccharides, psyllium husks and seeds, soya oil, glucosamine from fermentation, marigold meal, hydrolysed cartilage (source of chondroitin). *L.I.P.: protein selected for its very high digestibility.
Against the range

One recipe, built for weight loss in giant dogs. Poultry protein leads with vegetable fibres straight behind it, and fat is held to 11.0% as fed. Fibre comes from five places on the label, cellulose powder the bluntest of them.

A dog on this food is usually bigger than 15 kg and on a deliberate cut, so set the amount against the target weight.

Middle of the market for a dry food, and you pay a premium for what the analysis shows.
