Leader Adult Sensitive Large Breed review

57/100Good
DryAdult

A deliberately quiet recipe for big dogs whose digestion is easily upset, in our Good band in both lamb and salmon. What sets it apart is the fat: sunflower oil stands in for the chicken fat most kibbles use. Each bag has one animal protein and a short plant tail, and L-tryptophan is printed with a figure.

Our view

Likely to suit

  • Large dogs with touchy stomachs, the dog this was written and sized for
  • Homes keeping a dog off chicken
  • Plain cereals only: brown rice and white rice, nothing else
  • A highly strung dog, with L-tryptophan declared at 100 mg per kilo

Worth watching

  • An unnamed hydrolysed liver protein, which rules both out for a strict elimination trial
  • Modest fat and carbohydrate above the adult dry norm, so a hard-working large dog may need a bigger bowl

The details

Dog fit

Listed for large adult dogs. Big dogs eat well beyond the reference dog, from 225 grams at 20kg to 408 grams at 45kg on the pack, so weigh out the first bag.

The score, in context
  1. Leader Adult Sensitive Large Breed 57.0
  2. Salmon 55.9

All two Good. Typical dry food: Good.

Both sit at the centre of the adult dry category, so close together that the protein you need should decide it.

What's in it
  • Dehydrated lamb27%Dehydrated, so the figure holds through cooking.
  • Brown rice, white riceThe only grains. Bland and easily digested; no wheat, maize or soya.
  • Sunflower oilWhere most kibbles use chicken fat.
  • Potato proteinLifts the protein total without a second animal.
  • Whole linseedPlant omega 3, a slower road to a glossy coat than fish oil.
  • Minerals, alfalfa, seaweed mealSeaweed brings iodine and trace minerals.
  • Hydrolysed liver proteinThe palatant, and the one entry with no species named.
  • Yeast extract, chicory inulinInulin feeds the bacteria already in the gut.
  • Yucca schidigeraThe one owners notice out on the lawn.

Vitamins A, D3 and E with copper, selenium, iron, manganese, zinc and iodine, all dosed, plus L-lysine at 1,780mg and L-tryptophan at 100mg a kilo.

Hydrolysed liver protein names no species, so this cannot anchor a strict elimination trial.

The leaner bag, and the one for a big dog that has eaten enough poultry for one lifetime.

Both bags follow one recipe: a single dehydrated animal protein at the top, brown and white rice for starch, sunflower oil for fat and potato protein behind the meat. The plant tail is short, with linseed, alfalfa, seaweed meal and chicory inulin. Dehydrated meat keeps its percentage through the oven, which a fresh meat figure would not.

L-lysine and L-tryptophan are dosed on both labels. What differs is the animal and the trace mineral doses, which run higher on the lamb.

Budget end of the market for a dry food, though the analysis gives back a little less than the price suggests.
