Eukanuba was founded in 1969 by nutritionist Paul Iams with a single purpose: to produce dog food based on what nutritional science actually said dogs needed, not on what was cheapest to manufacture. While the brand later separated from IAMS under Procter & Gamble’s ownership, it retained the premium tier of Iams’s original vision โ and today positions itself firmly as a performance and breed-science brand.
Eukanuba’s most distinctive contribution to the UK pet food market is their Breed Specific Formula range โ dedicated recipes formulated around the physiological characteristics of specific breeds including the Labrador Retriever, German Shepherd, Yorkshire Terrier, and Pomeranian. While Royal Canin also offers breed-specific food, Eukanuba’s breed formulas tend to have a higher declared meat protein content and focus more explicitly on performance nutrition than Royal Canin’s more clinical approach.
With 215 products across dry adult, puppy, senior, breed-specific, daily care, and wet food categories, Eukanuba represents one of the most comprehensive single-brand ranges available through ZooPlus UK. We’ve reviewed the complete range for 2026.
What Makes Eukanuba Different?
- Chicken as primary protein: Every Eukanuba dry food uses chicken or chicken meal as the primary protein. There are no red-meat-forward formulas in the standard range โ the brand’s research has consistently returned chicken as the most bioavailable and digestible protein for the widest range of dogs.
- DentaDefense technology: Eukanuba’s kibble shape and coating includes STPP (sodium tripolyphosphate) which binds to calcium in saliva and prevents tartar mineralisation on the tooth surface. The effect is independently validated and their packaging carries the VOHC seal.
- 2x concentrated omega fatty acids: Eukanuba uses a fish-oil supplementation strategy at twice the concentration of many competitors’, specifically targeting coat quality and skin barrier function.
- Breed Specific range: Formulas calibrated per breed โ Labrador Retriever Adult includes L-carnitine (Labradors are obesity-prone), German Shepherd includes specific fibre ratios (the breed has high rates of digestive sensitivity), and small-breed formulas use smaller kibble sizes and higher calorie density.

Our Detailed Reviews
1. Eukanuba Adult Medium Breed Chicken โ Best Everyday
The Adult Medium formula is the core of the Eukanuba range โ a well-balanced, science-led daily food for dogs between 10โ25kg at a competitive price point. Chicken as the first ingredient, STPP for dental health, balanced omega-3 and omega-6 for coat condition, and a well-validated mineral profile for kidney support and urinary health. It does not push into premium grain-free territory, but for owners who want a research-backed conventional food without compromise on the basics, it is a strong choice.
Why we chose it: The DentaDefense dental coating sets Eukanuba apart from most competitors at this price point. For dogs who do not receive regular dental chews or toothbrushing, a food that actively reduces tartar formation is meaningfully better than one that does not.

The Labrador Retriever adult formula is probably Eukanuba’s most celebrated single product. The formula includes L-carnitine โ an amino acid derivative that promotes fat oxidation and lean body mass maintenance โ in concentrations specifically calibrated for Labradors, who are statistically the most obesity-prone breed in the UK. It also includes DentaDefense, prebiotics for the Labrador’s notoriously sensitive digestive system, and a calorie density 10% below standard adult food to account for Labs’ tendency to overeat whatever portion they receive.
Why we chose it: If you own a Labrador, this product is designed for your dog’s specific physiology in a way that no generic “adult medium” formula can match. The L-carnitine inclusion alone justifies the choice โ it is the only widely accessible non-prescription food in the UK that addresses the Labrador’s metabolic tendency directly.

3. Eukanuba Puppy Small & Medium Lamb & Rice โ Best Puppy Option
The lamb and rice puppy formula is Eukanuba’s hypoallergenic-leaning puppy food โ using lamb rather than chicken as the primary protein for puppies whose breed lines carry known food sensitivities (Irish Setters, Dalmatians, and many Spaniels are notable examples). The higher protein percentage (32%) reflects the growth requirements of puppies compared to adult maintenance, and the DHA supplementation supports neurological development during the critical first year.
4. Eukanuba Daily Care Working & Endurance โ Best for Active Dogs
The Working & Endurance formula is specifically designed for dogs in demanding physical roles โ gundogs, agility dogs, farm working dogs, and any dog covering significant mileage daily. At 30% protein and 20% fat (the highest fat content in the Eukanuba range), it provides the calorie density to sustain sustained aerobic activity without requiring the dog to eat large meal volumes that could cause exercise-associated GI distress. Priced per-kg at one of the most economical points in the working-dog food market.
Eukanuba vs IAMS: What’s the Real Difference?
IAMS and Eukanuba were sister brands under P&G ownership before both were sold to Mars in 2014. Today they maintain distinct positioning: IAMS targets the mid-market everyday owner with research-backed conventional food, while Eukanuba targets performance, breed-specific, and life-stage precision buyers who want a step up in specificity.
In practical terms, Eukanuba’s DentaDefense coating, breed-specific L-carnitine additions, and the Working & Endurance formula represent meaningful differentiations from IAMS’s range. If breed-specific formulation matters to you, Eukanuba is the choice. If you simply want a solid everyday food backed by good nutritional science, IAMS Advanced Nutrition delivers the same core value.
