Royal Canin Giant Adult review

46.4/100Average
DryAdultSenior

A dense, joint-minded kibble for dogs measured in stones, and it delivers what it promises. Dehydrated poultry proteins head the list, and the glucosamine comes from fermentation, not shellfish. It lands in our Average band, largely on how little the label names.

Our view

Likely to suit

  • Giant breed adults and seniors, the size it is portioned and packed for
  • Shellfish-free homes. The glucosamine is made by fermentation
  • Big dogs who struggle to eat enough in a sitting, at 418 kcal per 100g
  • A list that opens with meat before any grain

Worth watching

  • Wheat flour, maize gluten and wheat gluten, so plants supply a good share of the protein
  • No animal entry names a bird or a beast
  • Fish oil beside the algal oil, so not fish free

The score, in context
  1. Royal Canin Giant Adult 46.4

All one Average. Typical dry food: Good.

The analysis is not the problem; the marks come off for unnamed animal entries and three plant proteins topping up the meat.

What's in it
  • Dehydrated poultry proteinsAlready dried, so it still heads the list after the oven. Any bird.
  • Wheat flour
  • Animal fatsNo species named.
  • Maize flour, maizeThe starch.
  • Vegetable fibres
  • Hydrolysed animal proteinsUnnamed species.
  • Maize gluten, beet pulp, wheat glutenThe glutens lift the protein figure with plant protein a dog makes less of.
  • Minerals, soya oil, yeast products
  • Fish oil, algal oil (Schizochytrium)Omega 3 from two directions; the algae are where oily fish get theirs.
  • Glucosamine from fermentation, marigold meal, hydrolysed cartilageJoint pair with no shellfish behind it.

Vitamins A and D3 with iron, iodine, copper, manganese, zinc at 131 mg a kilo and selenium, plus clinoptilolite, a mineral clay used in the making.

With nothing animal named, this cannot be the food you use to prove which ingredients your dog reacts to.

A 15kg dog eats (our estimate)

Cost per day, 15kg dog
£1.07

A giant breed eats far more than the 15kg figure: the label asks 511 grams a day for a 60kg dog at low activity.

Mid-market for a dry food, and you pay a little more than the analysis alone would justify.
