Lighter, more satisfying diets that help pets reach and keep a healthy weight — high in protein and fibre, with feeding guides that actually work.
High-protein, high-fibre recipes that help pets feel full on fewer calories.
Lower-calorie recipes that still meet every nutrient requirement per 1000 kcal.
Protein and L-carnitine to protect muscle during weight loss.
Clear, calorie-based guides — the part owners get wrong most often.
Calorie terms such as “light” or “lean” follow defined calorie thresholds in each market; weight-loss claims need study support.
Peer-reviewed studies in dogs and cats — including where evidence is limited — and how each one shapes our formulation.
A high-protein, high-fibre diet reduced voluntary food intake by 51% compared with a high-protein diet in a canine satiety trial.
Satiety recipes are built on protein and fibre together, not one alone.
Across 926 dogs in 27 countries, 97% lost weight on high-protein, high-fibre diets (mean 11.4%), but only 7% reached their target weight.
Feeding guides and follow-up matter as much as the recipe.
In a 2022 US survey, 59% of dogs and 61% of cats were classified as overweight or having obesity.

Every project at Guires Pet Nutrition Lab runs inside an ISO 9001:2015 certified quality system and FSSAI-licensed operations, with documented methods, calibrated instruments, traceable raw materials and reviewed reports — so the results behind your product can be checked and defended.
Tell us the pet, the format and the markets — we will come back with an evidence-based development plan.
Every Guires PNL product is formulated to comply with the FEDIAF Nutritional Guidelines and the AAFCO Dog and Cat Food Nutrient Profiles. Neither body issues certificates to manufacturers, so compliance is verified independently against their published standards — and every product comes with a complete documentation package for regulatory submissions in the EU, US, Australia and Asian markets.
