N&D Spirulina Adult Medium & Maxi – Lamb, Spirulina & Wolfberry

Natural & Delicious

Natural & Delicious N&D Spirulina Adult Medium & Maxi: Lamb, Spirulina & Wolfberry review

71.8/100Excellent
DryAdult

A grain-free kibble with a large declared meat share and an algae and berry theme running through both bags. Each builds its protein from a fresh and a dehydrated portion of the same animal, then sets it on sweet potato. Both sit in our Excellent band, a rung above the typical adult dry food.

Our view

Likely to suit

  • Medium and larger adult dogs, the size the kibble and portions are drawn for
  • Dogs with cereal off the menu
  • Older dogs and heavy movers, with glucosamine and chondroitin in the recipe
  • Spirulina at 5% and wolfberry at 2.5% in each bag
  • Dogs that empty the bowl and go looking for work

Worth watching

  • Herring and herring oil in both, so neither suits a dog kept off fish
  • No quantity printed for the joint pair
  • Energy at 397 and 393 kcal per 100g, so measure the scoop for a steadier dog

The details

Dog fit

Listed for medium and larger adult dogs. Both kibbles are energy dense, so weigh the daily amount from the label's table and let the waistline decide.

The score, in context
  1. Lamb 71.8
  2. Herring 71.0

All two Excellent. Typical dry food: Good.

Nothing showy: a large named meat share, a lighter carbohydrate load and a chelated panel all point the same way.

What's in it
  • Lamb22%
  • Dehydrated lamb protein20%Sized to carry much of the protein.
  • Sweet potato
  • Chicken fatA second animal.
  • Dried spirulina5%
  • Dried eggs, herring, dehydrated herring protein, fish oilEgg and fish too, so this is a mixed-animal recipe.
  • Dried wolfberry2.5%
  • Inulin, fructo-oligosaccharides, yeast extractFood for the gut bacteria.
  • Dried spinach, psyllium, sodium chloride, brewers' yeast, turmeric, aloe vera
  • Glucosamine, chondroitin sulphateNo quantity printed.

Vitamins dosed in full, every trace mineral as a chelate, selenium from selenised yeast, and taurine, L-carnitine and DL-methionine printed.

Chicken fat, egg and herring all sit behind the lamb, so it is not a lamb-only food.

The red-meat option, best read as a mix of animals.

Each bag opens with a fresh meat and its dehydrated protein, herring at 24% and 23% in one, lamb at 22% and 20% in the other. Sweet potato is the only substantial starch, with pea fibre and psyllium behind it and no cereal anywhere. Dried spirulina at 5% and dried wolfberry at 2.5% run through both.

Prebiotics, turmeric and aloe sit near the end, and glucosamine and chondroitin close the list without a printed quantity. The vitamin and mineral panel is identical and every trace mineral is a chelate.

Premium end of the dry market, and the recipe goes a long way to justify the price.
