N&D Spirulina Adult Mini – Herring, Spirulina & Wolfberry

Natural & Delicious N&D Spirulina Adult Mini: Herring, Spirulina & Wolfberry review

67.8/100Good
DryAdult

Two grain-free recipes cut small for little jaws, both in our Good band. Herring or lamb leads, declared fresh and again as dried protein. The mineral panel is where the label really opens up: complete, dosed and chelated.

Our view

Likely to suit

  • Small-breed adults, kibble and feeding table both sized for them
  • Dogs that do better without cereal
  • Dogs starting to stiffen up
  • Little dogs with big appetites, a lot of fat and animal protein in a small portion
  • Owners taken with the algae and berry angle

Worth watching

  • Herring and herring oil in both bags, so neither suits a dog kept off fish
  • No quantity beside the joint pair
  • At 397 and 393 kcal per 100g, a small dog reaches its daily total quickly

The details

Dog fit

Listed for small adult dogs. The label asks 60 to 110 grams a day for a 5kg dog, so weigh the portion; it is a rich kibble.

The score, in context
  1. Lamb 68.5
  2. Herring 67.8

All two Good. Typical dry food: Good.

A comfortable place in a crowded field, earned by big named animal shares and a complete chelated mineral panel.

The easier bag for narrowing a small dog down to one animal; fish is its only declared allergen.

Both recipes lead with an animal declared twice, once fresh and once as dehydrated protein; the dried half is the one whose weight survives the oven. Sweet potato does the binding and neither bag holds any cereal. Dried spirulina at 5% gives the range its name, with dried wolfberry, the berry better known as goji, at 2.5%.

Pea fibre, psyllium, prebiotics, and undosed glucosamine and chondroitin run through both, on the same chelated mineral panel. Carbohydrate sits at 35.8% to 36.7% of dry matter. What separates them is how many animals are on the label.

Our costing uses a 15kg dog; a small dog's bowl is far smaller.

Premium end of the market for dry food, and the analysis gives back a little less than the price.
