K9 Optimum dog food review
K9 Optimum splits neatly between dry food and wet, with chicken as the protein on all thirteen products. Both formats cover every life stage, and twelve recipes add joint support extras. The brand average sits in our Good band, with Outstanding transparency on most of the list. Protein and processing is the pillar holding it there.

In detail
K9 Optimum: the closer look
The range
Thirteen products in all: seven dry and six wet. Adult dry comes in mini, medium and maxi. There are also two puppy sizes and a medium and maxi senior. Cans are among the wet list, which holds adult, puppy and senior recipes. Adult accounts for nine labels, puppy for four and senior for three.
Ingredients
Chicken is the only leading protein across the range. Glucosamine turns up on twelve products, with chondroitin on the wet recipes and salmon oil on most labels. Taurine and yucca are on the kibble, and so is linseed. Four recipes are flagged grain free.
Nutrition
Protein as fed runs from 8.0% on the cans to 30.0% on the puppy kibble, with energy from 89 to 362 kcal per 100g. Nutritional balance is the stronger nutrition read, Outstanding on six products, while protein and processing reaches Excellent on only three.
Strengths
- Outstanding transparency on ten products
- Joint support on twelve of thirteen
- Dry and wet under one brand
Limitations
- Chicken is the only leading protein
- Protein and processing reads Average on four
- No raw or fresh food
Where it is less of a fit
- If you want a protein other than chicken, check the labels, as chicken leads all thirteen products
- If the dry food should match the wet, check the scores: protein and processing sits at Average on four products
- If raw or fresh food is your dog's diet, check the formats, since this brand is dry and wet only
Score overview
Transparency carries the Good band read, Outstanding on ten products and Excellent on the other three. Nutritional balance helps, Outstanding on six. Protein and processing is the drag, Average on four. The three products that reach Excellent are all wet, and the rest of the list reads Good.
The average score is the mean of each product's overall score out of 100 (using the best-scoring variety per product), not a flat average across every variety.
