57.5/100Good

Our view

Likely to suit

  • Large-breed adults whose owners want joint ingredients in the food itself
  • Dogs that do well on plain chicken and rice
  • Genuinely huge dogs: the feeding table tops out at 80kg
  • Steady, moderately active dogs, on fat at 13.0% and an estimated 350 kcal per 100g

Worth watching

  • Every named animal ingredient is chicken, so a chicken sensitivity rules it out
  • No calcium declared, so keep it for the adults in the house

The score, in context
  1. Leader Adult Supreme Large Breed 57.5

All one Good. Typical dry food: Good.

A steady result: transparency reads Excellent, and the rice base keeps both nutrition pillars at Average.

What's in it
  • Dehydrated chicken26%Moisture already gone, so bag and bowl carry much the same share.
  • Brown rice, white riceA low-drama base for a dog with no grain issue.
  • Chicken fatNamed to species.
  • Dehulled oats
  • Whole linseedPlant omega 3: a steady contributor, no quick fix for a dull coat.
  • Minerals, alfalfa
  • Hydrolysed liver protein, yeast extractThe liver names no animal.
  • Chicory inulin, dried cranberries, dried beetroot
  • Rosemary, ginger, turmeric, yucca schidigeraRosemary stops the fats turning; yucca for what a big dog leaves on the grass.
  • Glucosamine hydrochloride, chondroitin sulphateNo figures printed, so a supportive touch.

Vitamins A, D3 and E, with zinc split between oxide and an amino acid chelate, iron, copper, manganese, iodine and selenium.

No calcium declared. Keep this bag for adults, not a growing large breed.

Costed for a 15kg dog. A real large breed eats a good deal more.

Budget end of the market for a dry food, though the price runs a little ahead of what the analysis shows.
