K9 Optimum
K9 Optimum Grain Free Dry Adult review
The cereal-free build of the K9 Optimum range, and it lands in our Good band. The footnote promising a minimum of 55% chicken and salmon is a commitment most labels avoid. Every extra comes with a number attached.
Our view
Likely to suit
- Dogs kept off grain, with sweet potato and potato as the starch
- Owners who like extras quantified: glucosamine and MSM at 200 mg per kilo, green lipped mussel at 150 mg
- Mixed households. The table runs from a 1kg dog to one over 40kg
- Dogs that get along with chicken
- Gut comfort, with MOS at 1650 mg per kilo and FOS at 400 mg
Worth watching
- Salmon and salmon oil, for a dog kept off fish
- Potato protein lifting the protein figure from a plant
- Nearly all the meat is chicken

The score, in context
- K9 Optimum Grain Free Dry Adult 66.9
All one Good. Typical dry food: Good.
The best reading in the K9 Optimum range, and the gap to the cereal recipes is mostly the base, not the meat.
What's in it
- Chicken: freshly prepared, dried20%, 19%The dried share is the one that counts; fresh meat gives up its water in cooking.
- Sweet potato, potatoDo the cereals' job. Sweet potato is the slower burning.
- Chicken fat, chicken gravy
- Salmon4%Freshly prepared.
- Beet pulp, egg powder, brewer's yeastBeet pulp does most of the stool work; egg is a small complete protein.
- Lucerne, full fat linseedLucerne is alfalfa. Linseed adds plant omega 3.
- Potato proteinLow on the list, supporting the meat. Doing arithmetic as much as nutrition.
- Salmon oil1%Marine omega 3.
- Turmeric, MOS, FOS, glucosamine, MSM, yucca1650 down to 200 mg/kgDosed at levels you can see, not a token sprinkle.
- Marigold, blackcurrant, NZ green lipped mussel, rosemary, pomegranate150 mg/kg mussel
Vitamins A, D and E with taurine and carnitine, zinc as a sulphate plus a glycine chelate, and selenium as sodium selenite.
