K9 Optimum
K9 Optimum Puppy Maxi review
A large breed growth kibble that gets the number that matters right: calcium at 1.09% of dry matter, where a big pup's bones want it. Two forms of chicken lead, salmon appears three ways behind them, and DHA has its own named source. It sits in our Good band.
Our view
Likely to suit
- Large breed puppies, with calcium printed and in range
- Owners who want brain and eye nutrients named, from marine algae and marigold
- Puppies that thrive on chicken
- Homes happy with fish in the bowl
- A steadier energy level, at an estimated 357 kcal per 100g
Worth watching
- Prairie meal mid-list, unexplained and with no species
- Glucosamine, mussel and MSM with no doses, so a gesture towards joints
- Chicken, salmon and egg together, so neither single-protein nor fish free
- Rice and maize high up, with carbohydrate at an estimated 43.5% of dry matter

The score, in context
- K9 Optimum Puppy Maxi 63.2
All one Good. Typical dry food: Good.
A declared, in-range calcium figure on a bag sold for big pups earns the placement; the rice and maize starch and the undosed tail keep it there.

One large breed puppy kibble: dried and freshly prepared chicken first, then rice and maize, salmon in three forms, and marine algae named as a DHA source. A long tail of joint and gut extras follows without doses.
