Royal Canin Giant Starter review

43.5/100Average
DryPuppyAdult

A dense, high-energy kibble for the first stage of a giant breed's life, and it settles in our Average band, a step short of the typical adult dry food. The gap comes from the label's silence, not the analysis. Protein is declared at 30.0%, fat at 22.0%, and the DHA comes from an algal oil.

Our view

Likely to suit

  • Giant breed youngsters at the start of their growth
  • Owners weaning a big litter, with guidance split into 0 to 4 months and 4 to 12 months
  • A lot of nutrition in a small volume, at 417 kcal per 100g
  • Unsettled young digestions: psyllium husks and seeds, hydrolysed yeast and fructo-oligo-saccharides are all named

Worth watching

  • No calcium figure on a giant breed growth food. Ask the maker before it becomes the everyday bag
  • Not one animal entry named to a species, from the poultry protein to the hydrolysed proteins
  • Wheat gluten fourth, and fish oil beside the algal DHA, so it is neither wheat nor fish free

The score, in context
  1. Royal Canin Giant Starter 43.5

All one Average. Typical dry food: Good.

The analysis is the best thing here; a label that never names a species, leans on wheat gluten and leaves out calcium is what holds the score down.

What's in it
  • RiceLeads the list.
  • Dehydrated poultry proteinThe bird is never named.
  • Animal fatsNo species.
  • Wheat glutenChosen for how well it digests, so some of the declared protein is cereal.
  • Hydrolysed animal proteins
  • Maize, beet pulp, minerals, soya oil, vegetable fibres
  • Fish oilPuts fish in the bag alongside the algal DHA.
  • Psyllium husks and seeds, fructo-oligo-saccharidesSoluble fibre, and food for the gut's own bacteria.
  • Hydrolysed yeast, butyric acid salt0.30% (yeast)Manno-oligo-saccharides and betaglucans, with the salt there for the gut lining.
  • Algal oil Schizochytrium, marigold mealDHA for a developing brain and eye.

Vitamin D3 at 1200 IU and zinc at 135 mg per kilo lead a mineral load bigger than an ordinary adult kibble carries.

No calcium declaration on a food for a giant breed at the very start of life. Ask Royal Canin for the level.

Named ingredients

Rice, dehydrated poultry protein, animal fats, wheat gluten*, hydrolysed animal proteins, maize, beet pulp, minerals, soya oil, vegetable fibres, fish oil, psyllium husks and seeds, fructo-oligo-saccharides, hydrolysed yeast (source of manno-oligo-saccharides and betaglucans) (0.30%), algal oil Schizochytrium sp.

Against the range

One concentrated growth kibble for giant breeds. Rice and dehydrated poultry protein lead, wheat gluten sits fourth, and a digestive kit of psyllium, fructo-oligo-saccharides and hydrolysed yeast runs through the tail. Calcium is not declared.

A growing giant breed eats well beyond the 15kg adult figure, so read it only as a comparison point.

Middle of the market for a dry food, a little more than the analysis on its own would justify.
