K9 Optimum
K9 Optimum Adult Maxi Breed review
A well-labelled everyday kibble for big adult dogs, in our Good band. It puts its meat where you can check it, two chicken entries with their shares, and it finishes with a run of joint ingredients for a frame with years of weight-bearing ahead. None of those joint extras carries a dose.
Our view
Likely to suit
- Large-breed adults. The recipe and the feeding table are both drawn around them
- Owners thinking ahead about joints: glucosamine, methylsulphonylmethane and green lipped mussel are all listed
- Dogs happy on chicken, the only meat besides salmon
- Animal ingredients named, from the chicken fat to the salmon oil
- Steadier big dogs, as the maker's table assumes low activity
Worth watching
- Salmon and salmon oil, so no part of the bag is fish free
- Mostly chicken, which rules it out after a past reaction to chicken
- A big dog in hard work will need more than the low-activity table shows

The score, in context
- K9 Optimum Adult Maxi Breed 60.1
All one Good. Typical dry food: Good.
Named meat does most of the work here; an ordinary rice and maize starch load is what holds nutritional balance back.

This is a big-dog food, so the daily amount sits well above the 15kg estimate: 285 to 330 grams for a dog of 25kg to 30kg.
Budget end of the dry market, though you pay a little more than the analysis shows.
