We find, assess and approve ingredient suppliers for pet food manufacturers — on documentation, testing and risk, not on price alone.
Sourcing and procurement for pet food, treat and supplement manufacturers — every ingredient bought to a specification and verified by testing.
Shortlists of suppliers for proteins, fats, carbohydrates, fibres, vitamins, minerals, palatants and functional actives.
Specifications, certificates of analysis, origin, allergen, GMO and process statements checked for completeness.
Proximate, contaminant and identity testing of supplier samples before approval.
Each ingredient and supplier rated for safety, quality and supply risk.
Supplier audits arranged through our partner network for high-risk materials.
A maintained list with re-approval dates, so qualification does not lapse.
Mycotoxins, heavy metals and pathogens usually enter a pet food through its raw materials.
Meals and hydrolysates can carry undeclared species that break single-protein claims.
Certificates of analysis often cover fewer parameters than a pet food needs.
A change of origin, process or carrier can alter a material without its name changing.
Ingredients, volumes and markets agreed.
Suppliers shortlisted.
Technical files reviewed.
Samples analysed before approval.
Risk-rated approval decision.
Re-approval on a schedule.
Peer-reviewed findings that shape how we design and interpret this work.
A 2026 survey of 126 dog and cat foods found fumonisin B1 in over 94% and more than one mycotoxin in over 92% of products.
Multi-mycotoxin screening of ingredients and finished product, not single-toxin tests.
In a 2025 survey of 93 products, 8.6% exceeded lead limits; in another study, ingredients such as wheat bran carried higher metal levels.
Heavy-metal testing of both raw materials and finished product.
DNA studies keep finding undeclared species — 23 of 40 novel-protein and hydrolysed diets in one study.
For single-protein and novel-protein products we specify single-source raw materials, require supplier declarations and design out cross-contact in the recipe and process.
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.
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.
Keeping active and ageing pets moving comfortably.
Lighter, more satisfying diets that help pets reach and keep a healthy weight.
Proteins, fats, fibres, palatants and functional actives are qualified against a specification written for pet food — including the contaminants and identity checks a general certificate of analysis leaves out.
Regulation updates, the latest research, recalls and market trends that shape ingredient sourcing — written by our formulation, testing and regulatory teams.
No. We can qualify suppliers you already use, find new ones, or both.
Where the risk calls for it, site assessments are arranged through our partner network.
Proteins, fats and oils, carbohydrates, fibres, vitamins, minerals, premixes, palatants and functional actives.
Clients in the USA, UK and UAE on working with Guires PNL. Names are withheld at clients’ request.
“Finding novel proteins with consistent specifications was holding back our development. Their sourcing team shortlisted qualified suppliers and compared specifications side by side, which made our procurement decisions straightforward.”
“From supplier identification to specification reviews and batch testing, they handled every step of ingredient sourcing. We knew each raw material suited our formulation before placing an order.”
“We needed dependable suppliers of functional ingredients for our pet supplement range. They assessed quality standards, commercial terms and long-term supply options, giving us the full picture before we committed.”
Tell us your product, your question and your market — our scientists will come back with a study design and next steps.
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.
