K9 Optimum Adult Mini review

63.3/100Good
DryAdult

Good under our scoring, and the meatiest of K9 Optimum's cereal-based recipes. The dried chicken at 19% is placed ahead of the fresh at 18%, an order that helps, and protein reaches 30.8% of dry matter. Salmon, salmon meal, salmon oil and marine algae give a small dog a proper marine omega supply.

Our view

Likely to suit

  • Small breed adults. The feeding table is drawn for dogs between 4kg and 9kg
  • Little dogs that need density in a small bowl: protein at 30.8% of dry matter
  • An older small dog, as marine algae supplies DHA
  • Dogs in need of a bit of shine, from salmon oil and full fat linseed at 1% each
  • Fussy small eaters. Chicken gravy sits high on the list

Worth watching

  • Fish four times over, which matters for a fish-avoiding dog
  • Rice and maize both in the top four
  • Joint extras with no amounts, so read them as encouragement
  • Chicken carries the meat almost single-handed

The score, in context
  1. K9 Optimum Adult Mini 63.3

All one Good. Typical dry food: Good.

Protein is what clears the bar, and for a small dog the practical reading is a dense, well-labelled bowl with a marine omega supply most small breed foods leave out.

What's in it
  • Chicken dried19%Ahead of the fresh, so more of the labelled meat reaches the finished kibble.
  • Chicken18%Sheds most of its weight as water in the cooking.
  • Rice, maizeA fair share of the starch.
  • Chicken gravyA palatant, no small thing for small dogs that turn their nose up.
  • Salmon, salmon meal4%, salmonFish protein as well as fish oil.
  • Chicken fat, whole oats, prairie meal, brewers yeast, beet pulpOats and beet pulp for fibre; yeast brings B vitamins.
  • Full fat linseed, salmon oil1% eachPlant and marine omega 3, working at different speeds towards the same end.
  • Egg powder, marine algaeAlgae is there for DHA, the omega 3 the brain, eyes and nerves use.
  • MOS, nucleotides, marigoldA prebiotic, then a bonus; marigold for lutein.
  • Glucosamine, green lipped mussel, MSM, turmeric, fruit and herbsNo amounts given.

Dosed throughout: taurine, zinc as a glycine chelate and a sulphate, and selenium as sodium selenite at the usual small dose.

A small dog food, so the maker's table matters more than our 15kg figure.

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