Purizon is ZooPlus’s own-label premium dog food brand โ but do not let the “own-brand” label mislead you into assuming it is a budget compromise. The Purizon range was specifically developed to outperform most market-priced branded alternatives on one critical metric: the ratio of named meat protein to total ingredients.
Where many premium-branded dry dog foods achieve 25-35% declared crude protein using a blend of meat and plant proteins, Purizon typically declares 40-43% crude protein with the first ingredient being fresh chicken meat or salmon at concentrations of 55-70% (before moisture adjustment). This is genuinely high by industry standards and explains why Purizon has developed a cult-like following among UK owners who read ingredient labels carefully.
We’ve reviewed the complete Purizon range available in the UK for 2026, covering the core Adult formula, the Single Meat specialist range, and the life-stage variants.
The Purizon Philosophy: Four Simple Rules
- No grains. Every Purizon product is grain-free โ no wheat, no maize, no barley, no oats. Carbohydrates come from tapioca, potato, chickpeas, or sweet potato โ all significantly better tolerated by the canine digestive system than cereal grains.
- No artificial additives. Natural preservation only. Natural antioxidants (tocopherols) replace chemical preservatives like BHA and BHT.
- Named proteins only. “Chicken,” never “poultry.” “Salmon,” never “fish.” The percentage is always declared.
- Fresh meat, not just meal. Purizon formulas use fresh meat (high moisture, highly digestible) as the primary ingredient, supplemented with meat meal. This differs from cheaper formulas that use only meat meal as the protein source.

Our Detailed Reviews
1. Purizon Adult Chicken & Fish โ Best Overall Value
The flagship Purizon Adult formula consistently delivers the highest meat-to-price ratio of any retail grain-free dog food in the UK. Fresh chicken at 55% (pre-moisture) as the first ingredient, supplemented with herring and salmon oil, delivers a 43% crude protein figure that exceeds most brands charging significantly more per kilogram. The grain-free base uses tapioca โ a largely neutral carbohydrate with minimal allergen potential.
Why we chose it: For owners who want to feed their dog a genuinely premium ingredient profile without the boutique-brand premium price, Purizon Adult represents an exceptional proposition โ particularly in the 12kg and economy pack sizes where the cost per day of feeding becomes extremely competitive.

2. Purizon Single Meat Adult Chicken โ Best for Allergic Dogs
The Single Meat range takes Purizon’s quality standard and applies it to a strict single-protein protocol. One protein source (chicken), one carbohydrate source (tapioca), salmon oil for omega-3, and nothing else of consequence. For dogs on an elimination diet who need a grain-free single-protein dry food, this is the most competitive option available in the UK market without moving to veterinary prescription diets.
Why we chose it: The 70% declared fresh chicken content in the Single Meat formula is among the highest for any commercially available dry dog food in the UK at any price point. This is not a compromise single-protein food โ it is a genuinely excellent product that happens to also serve a clinical dietary need.
3. Purizon Senior Chicken & Fish โ Best for Older Dogs
The Senior formula adjusts macronutrient ratios for dogs aged 7 and above: slightly reduced crude protein (to account for reduced kidney function in ageing dogs), lower phosphorus, higher dietary fibre, and a supplemental dose of glucosamine and chondroitin for joint support. These adjustments are clinically appropriate without requiring a prescription diet.
Why we chose it: Many mainstream senior dog foods reduce protein primarily to cut costs, presenting it as a health feature. Purizon’s senior reduction is genuine and carefully calibrated โ the protein is reduced specifically in the phosphorus-containing fraction while maintaining overall amino acid bioavailability.
Purizon vs Branded Premium Grain-Free Brands
Purizon consistently outperforms or matches brands like Acana Regionals, Orijen, and Canagan on declared meat percentage at a significantly lower price per kilogram. The primary advantage these boutique brands hold over Purizon is brand storytelling and transparency about sourcing geography (Acana’s Canadian sourcing, for example). On pure ingredient quality metrics, Purizon holds its own decisively.
The key caveat: Purizon is exclusively available through ZooPlus UK. If you prefer to buy from a local pet shop or Amazon, you will need a branded alternative. If your primary channel is ZooPlus anyway, Purizon is the most rational choice for a grain-free high-protein daily food.
For cats, the Purizon cat range applies the same philosophy. See also our Best Grain-Free Dog Food UK guide for broader market context.
