Diets that support a healthy urinary tract — through controlled minerals, target urine pH and more water intake, especially for cats.
Controlled magnesium, phosphorus and calcium for the target species.
Recipes designed to reach a target urine pH range.
Wet formats and hydration products that raise water intake and dilute urine.
Urine relative supersaturation (RSS) studies through partner facilities.
“Supports urinary tract health” for general foods; claims about urinary stones are veterinary-diet claims with their own rules.
Peer-reviewed studies in dogs and cats — including where evidence is limited — and how each one shapes our formulation.
Veterinary consensus recommends urine specific gravity of 1.020 or lower in dogs and below 1.030 in cats, favouring high-moisture foods that keep urine dilute — a recognised factor in calcium oxalate stone risk.
Hydration-led formats are part of every urinary range we design.
Diets with a struvite relative supersaturation below 1 dissolved struvite stones in a median of 18 days in cats.
RSS testing validates urinary recipes before claims are made.
Species, life stage, format and the benefit you want — checked against the published evidence.
Active levels and draft claims agreed per market before formulation.
Recipe built to nutrient profiles, with actives at evidence-based levels.
Actives measured in the finished product and through shelf life.
Palatability and, where claims need it, efficacy studies with partner panels.
Label, claim substantiation file and technology transfer.
Sets nutrient and active targets against AAFCO and FEDIAF profiles.
Reviews clinical relevance, safety and claim boundaries.
Verifies active levels, stability and safety in the finished product.
Checks ingredient status and claim wording in each market.
Stay ahead with regulation updates, the latest research, ingredient spotlights, recalls and market trends for functional nutrition — written by our formulation, testing and regulatory teams.
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.
