Complete recipes from your brief, species, life stage and target market — balanced on energy, costed, and verified by laboratory analysis.
A new formula has to satisfy dozens of nutrient minimums and maximums at once, balanced to its energy content, while working with real ingredients, a real process and a target price. Published surveys show how often finished foods still miss their targets — which is why calculation alone is never enough.
We formulate from species and life-stage requirements first, using analysed raw-material values rather than book values, calculate energy with the method each market requires, and verify every prototype by laboratory analysis before it moves to pilot.
Start your project with Guires PNLEvery formula is balanced on energy, checked against minimums and maximums for your market and verified by laboratory analysis.
A complete recipe built from your brief, species, life stage and target market.
A recipe designed to match or exceed a benchmark product’s positioning and nutrient profile.
Analytical and label-based assessment of competing products to set your targets.
Recipes built on insect, cultivated, plant-based or upcycled ingredients, with digestibility and amino acids checked.
Growth, adult, senior and large-breed recipes with tighter calcium and energy control.
Digestive, joint, skin, weight and urinary concepts with actives at evidence-based levels.
Nutrient profiles are set per 1000 kcal ME, so an inaccurate energy value distorts every nutrient check.
Excess is as dangerous as deficiency — vitamin D and calcium errors have caused recalls and skeletal harm.
Raw materials vary between suppliers and batches; book values hide that variation.
Vitamins and available amino acids fall during extrusion and retort, so overages are designed in.
Species, life stage, format, market and price.
Nutrient profile and energy basis set.
Recipe calculated and costed on analysed values.
Bench samples made and reviewed.
Laboratory analysis against targets.
Specification ready for pilot.
Peer-reviewed findings that shape how we design and interpret this work.
Only 6% of wet and 38% of dry UK foods met all FEDIAF mineral guidelines (2017); in 2025 none of 31 UK dry dog foods met every guideline.
Every formula is verified by laboratory analysis of the finished product against its targets.
Excess matters as much as deficiency. In 2018–19, formulation errors led to US dog food recalls with vitamin D at up to about 70 times the intended level.
Every formula is checked against FEDIAF nutritional maximums and EU/UK legal additive limits (e.g. vitamin D 2,000 IU/kg, zinc 200 mg/kg), and premix inclusion is double-checked.
Raw materials vary: in 200 samples of one poultry meal, ash varied by about 20%.
Formulas use analysed raw-material values, not book values, with specifications for each supplier.
Each application has its own page with the evidence, the actives and the claim boundaries we work within.
Firm stools, comfortable digestion and a balanced gut microbiome.
The right start for puppies and kittens, and the extra nutrition mothers need.
Lighter, more satisfying diets that help pets reach and keep a healthy weight.
A healthy skin barrier and a glossy coat, driven by the right balance of omega-6 and omega-3 fatty acids, protein quality and key micronutrients.
Every ingredient we choose for new formulation is assessed for nutrient contribution, digestibility, processing behaviour, palatability and the rules in your market — and sourced to your specification.
Regulation updates, the latest research, recalls and market trends that shape new formulation — written by our formulation, testing and regulatory teams.
The one your market requires — AAFCO for the US, FEDIAF for the EU and UK, and IS 11968 or an agreed international profile for India.
No. A brief is enough; a benchmark simply helps set targets for positioning and cost.

“Meeting AAFCO nutrient profiles while staying clean-label and within budget had defeated our in-house team. Their formulation achieved all three.”
“With no in-house nutritionist, we needed a hypoallergenic formula built from scratch. They delivered the full recipe, explained the reasoning behind every ingredient and supplied a specification our manufacturer used directly.”
“Our functional treat line needed targeted joint-health ingredients that stayed stable through manufacturing. The recipe they developed met both requirements and came with thorough nutritional records.”
Real client projects — the problem, the science and the result.
A first-time founder had a gently cooked dog food recipe customers wanted to buy — but the contract manufacturer’s first run failed. Guires PNL took the recipe through nutrient analysis, reformulation, pilot processing, testing, labelling and tech transfer to a first production batch in 90 days.

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.
