Development categories

What can be specified now, and what needs a trial.

Two different kinds of blocker, deliberately kept apart. Specification work is reachable today from public standards, calculation and analysis. A trial is not. Presenting them as the same thing reads as if nothing can proceed.

Complete diets

Meeting total nutrient requirements as the sole ration, across life stage and activity level.

Evidence today: Requirements are settled at standards level for every essential nutrient. Adequacy is a formulation and verification exercise rather than an open research question.
Specifiable now: The whole adequacy package. AAFCO recognises two substantiation routes and a feeding trial is the alternative, not a prerequisite — formulation to the recognised nutrient profile, verified by analysis, earns the same statement. That brings with it the guaranteed analysis, the calorie content statement by the prescribed calculation, and feeding directions derived from energy density.
Requires a trial: Digestibility, and any outcome claim on the finished formula. A calculated energy value must be declared as calculated; a determined value requires a metabolism study.

Performance nutrition

Sustaining work capacity, thermal tolerance and recovery between sessions in dogs doing repeated physical work.

Evidence today: Energy demand dominates and is context-dependent — measured requirements in endurance work vary widely by load, terrain and temperature. Higher fat suits endurance; balanced macronutrients suit sprint work. Controlled data for agility, field-trial and detection work is sparse, so those recommendations are extrapolated.
Specifiable now: Energy density, by calculation from proximate analysis, and the macronutrient architecture the work type calls for. The market resolves performance into three defined rungs, so a target ratio can be set deliberately rather than by feel.
Requires a trial: Work capacity, endurance and recovery outcomes, and feeding rates for working dogs — measured expenditure runs 1.9 to 2.5 times the maintenance coefficient and swings with load, terrain and temperature. No equation predicts it from proximates.

Digestive support

Nutrient and protein digestibility, faecal consistency and volume, and hindgut fermentation.

Evidence today: The strongest evidence sits with fibre and diet rather than microbial ingredients. Fibre source measurably changes digestibility and faecal output. Probiotic effects in dogs are limited and strain-specific; postbiotic evidence in dogs is essentially absent.
Specifiable now: Fibre selection and inclusion, and a stability programme establishing viable count at end of shelf life under the actual packaging and storage conditions. Published surveys found only a minority of commercial probiotics met their own viable claim, so this is a real point of difference rather than a formality.
Requires a trial: Stool quality, faecal consistency and any digestive-health outcome on the finished formulation.

Mobility support

Maintaining comfortable, sustained movement in dogs at risk of degenerative joint change.

Evidence today: Energy control is the best-evidenced lever by a wide margin — lifetime restriction delayed first radiographic change by years. Among ingredients, long-chain omega-3 fatty acids rank highest; glucosamine and chondroitin performed comparably to placebo in blinded force-plate work.
Requires a trial: A controlled trial on the finished formula using validated outcome measures, plus stability data for the active fraction.

Skin & coat

Substrate supply for keratinisation, hair growth and epidermal integrity.

Evidence today: Linoleic acid, zinc and protein adequacy are settled at standards level, and deficiency in any of the three shows in the coat. EPA and DHA carry review-level support in haircoat disorder. Oil supplementation improved graded coat quality from baseline without changing transepidermal water loss — which argues against a barrier claim.
Requires a trial: Analytical ingredient verification and a controlled coat-scoring study on the finished product.

Toppers & treats

Palatability and voluntary intake, and a delivery format for complementary nutrition.

Evidence today: Treats and toppers are complementary feeds rather than complete diets, and are formulated against intake and caloric contribution rather than against a full nutrient profile.
Specifiable now: Caloric contribution and the feeding guidance that keeps the product inside a balanced daily ration — both calculable. Per-piece energy from proximate analysis, a maximum daily count by bodyweight, and the compensating reduction to the main ration, which is the step most brands leave out.
Requires a trial: Palatability and voluntary intake, which for a treat is the product's primary function and cannot be calculated. Any dental positioning needs product-specific efficacy data submitted through the recognised review route.

Formulation direction

What the evidence supports — and what it does not.

Development inputs, not finished formulas. Each candidate is graded on the published evidence, including the ingredients the evidence tells us to leave out.

Mobility support

Sustained comfortable movement in dogs at risk of, or living with, degenerative joint change.

Lead with

Energy control and body-condition management
Established
The best-evidenced nutritional lever on joint outcomes by a wide margin. Lifetime 25% food restriction pushed median first radiographic hip osteoarthritis from 6 years to 12. In obese dogs, lameness change became detectable from roughly 6% bodyweight loss subjectively and 9% on gait analysis. This is a formulation and feeding-guidance decision, not an additive.
Basis2006Controlled study 2010Controlled study
Long-chain omega-3 fatty acids (EPA/DHA)
Moderate
The highest-ranked functional ingredient in a 72-trial meta-analysis, and the only nutraceutical a 2012 systematic review found adequately supported in dogs. Whole-diet enrichment raised serum omega-3 and moved owner-assessed function over six months across 18 practices.
Basis2022Systematic review 2021Systematic review
Green-lipped mussel lipid extract
Moderate
Produced measurable change in force-plate peak vertical force in a blinded, placebo-controlled trial — objective gait data rather than owner impression.
Basis2023Controlled study

Deprioritise or exclude

Glucosamine and chondroitin sulfate
Counter-indicated
In the same blinded trial that showed marine lipids moving peak vertical force, glucosamine/chondroitin performed similarly to placebo, and the 2022 meta-analysis reported a marked non-effect. Category convention, not evidence, keeps this pairing in products.
Basis2022Systematic review 2023Controlled study

Claim ceiling. Nutrient contribution and normal structure-function only. Joint or mobility improvement claims name a body system beyond nutritive value and read as drug claims.

Substantiation required. A controlled trial on the finished formula in the target population using validated outcome measures, plus analytical verification and stability data for the active fraction.

Digestive support

Nutrient and protein digestibility, faecal consistency and volume, and hindgut fermentation.

Lead with

Fibre matrix — beet pulp and mixed fermentable/insoluble sources
Moderate
The strongest evidence in this category sits with fibre rather than microbial ingredients. Beet pulp raised dry matter and total dietary fibre digestibility and lowered wet faecal output versus cellulose and Miscanthus, with a documented trade-off against crude protein digestibility that formulation must balance.
Basis2026Consensus recommendations 2019Controlled study
Protein quality and digestibility
Established
Consensus veterinary guidance treats diet as the first-line intervention in chronic enteropathy, with hydrolysed and fibre-enriched formulations showing the highest response rates. Formulate on protein quality rather than crude protein alone.
Basis2006Nutritional standard 2026Consensus recommendations

Deprioritise or exclude

Probiotics as a headline ingredient
Emerging
A systematic review of 17 canine trials found a very limited and possibly clinically unimportant effect with moderate-to-high risk of bias, and consensus panels give probiotics only a weak recommendation. Effects are strain- and dose-specific and cannot be extrapolated between strains, so a named deposited strain with its own data is the minimum bar.
Basis2019Systematic review 2014Consensus recommendations
Clinoptilolite for canine digestive support
Insufficient
Genuinely promising in neonatal calves, but the canine evidence is close to absent — one unblinded ten-dog study in a non-indexed journal. The one controlled canine microbiota trial used a different zeolite with clinoptilolite absent, and the most rigorous trial against a diarrhoea endpoint in any species missed its primary endpoint.
Basis2026Regulatory guidance 2022Controlled study

Claim ceiling. Nutritive value only. Digestive-health and stool claims name a body system and require pre-market review.

Substantiation required. Controlled canine data on the specific finished formulation, verified viable counts at end of shelf life for any named strain, and defined inclusion levels.

Skin & coat

Substrate supply for keratinisation, hair growth and epidermal integrity.

Lead with

Linoleic acid, zinc and protein adequacy
Established
Requirements are settled at standards level, and deficiency of any of the three is associated with a dull, scaly or unkempt coat. Adequacy is the foundation; everything else is incremental.
Basis2006Nutritional standard
EPA/DHA
Moderate
A systematic review with formal risk-of-bias assessment identified benefit in canine haircoat disorder and allergic dermatitis, though in diseased animals under veterinary management rather than healthy-dog maintenance.
Basis2021Systematic review 2015Consensus recommendations

Deprioritise or exclude

Barrier-function positioning
Insufficient
A 16-week randomised trial in healthy dogs found graded coat improvement from baseline but no difference between oils and no measurable change in transepidermal water loss — which specifically argues against a skin-barrier claim.
Basis2023Controlled study
Allergy or sensitivity positioning
Counter-indicated
Diagnosis of adverse food reaction requires a veterinarian-supervised elimination trial with controlled rechallenge; serological, salivary and hair testing are not reliable. A product named for seasonal or environmental support must never read as an allergy treatment. Ingredient verification testing matters here regardless: a median 45% of commercial foods tested contained unlisted ingredients.
Basis2018Systematic review 2025Consensus recommendations

Claim ceiling. Nutrient contribution to normal skin and coat. No allergy, dermatitis or barrier-repair language.

Substantiation required. Formulation records against published requirements, analytical ingredient verification, and a controlled coat-scoring study on the finished product.

Performance and working-dog nutrition

Work capacity, thermal tolerance and inter-session recovery in dogs performing repeated physical work.

Lead with

Energy density and fat level matched to work type
Established
Energy demand dominates and is context-dependent — measured requirements in racing endurance dogs ranged from roughly 9,000 to an extrapolated 13,800 kcal/day between race legs, driven by load, terrain and temperature rather than distance. Higher fat suits endurance work; balanced macronutrients suit sprint work.
Basis2014Consensus recommendations
Palatable oral electrolyte for voluntary intake
Moderate
A flavoured electrolyte solution more than doubled voluntary fluid intake versus plain water in working detection dogs in a hot environment, making palatability-driven intake a legitimate design objective in its own right.
Basis2017Controlled study

Deprioritise or exclude

Performance or thermoregulatory claims from hydration
Insufficient
The same trial that doubled voluntary intake detected no effect on core body temperature or olfactory search performance. Intake is the demonstrated outcome; performance is not.
Basis2017Controlled study

Claim ceiling. Nutrient and energy contribution. No performance, endurance or recovery outcome claims.

Substantiation required. Energy density and digestibility data, a controlled feeding trial in the intended working population with objective work and recovery endpoints, and field voluntary-intake data.

2025 · Nutritional standard

Reading labels — nutritional adequacy statement formats

Association of American Feed Control Officials

Scope. Required label elements, the standardized nutritional adequacy statement formats, and what constitutes misbranding.

Supports. Gives the exact prescribed wording for each substantiation route and confirms that an incorrect adequacy statement, or a disease claim without an approved drug, is misbranding.

Does not establish. Does not carry force of law on its own — AAFCO models bind only where a state has adopted them, and AAFCO approves, certifies and endorses nothing.

2023 · Controlled study

Effectiveness of glucosamine and chondroitin sulfate, marine-based fatty acid compounds, and carprofen in dogs with hip osteoarthritis

Frontiers in Veterinary Science

Scope. Six-week block-randomised, double-blinded, placebo-controlled trial in 75 owned dogs measured against force-plate peak vertical force.

Supports. Objective gait evidence that marine lipid extracts can shift weight-bearing, and that glucosamine/chondroitin at 30 mg/kg/day performed similarly to placebo.

Does not establish. Does not extend beyond six weeks, found no significant between-group difference on subjective scoring, and was supported by a supplement manufacturer.

2022 · Systematic review

Systematic review and meta-analysis of enriched therapeutic diets and nutraceuticals in canine and feline osteoarthritis

Université de Montréal / International Journal of Molecular Sciences

Scope. Screened 1,578 publications and pooled 72 trials across nine categories of natural health compound in dogs and cats with osteoarthritis.

Supports. Ranks long-chain omega-3 fatty acids as the lead functional ingredient by effect size, and de-prioritises glucosamine–chondroitin.

Does not establish. Does not validate any commercial formulation; the authors flag subjective outcome tools, groups often under ten animals, and wide variation in dose and duration.

2021 · Systematic review

Therapeutic effect of EPA/DHA supplementation in neoplastic and non-neoplastic companion animal diseases: a systematic review

In Vivo

Scope. Systematic review of randomised controlled EPA/DHA studies in dogs and cats with Cochrane RoB2 risk-of-bias assessment; 23 studies included.

Supports. Identifies benefit in canine allergic dermatitis and haircoat disorder among included trials — the strongest single citation for an EPA/DHA coat rationale.

Does not establish. Does not establish effect size, dose or duration for a healthy-dog maintenance product; benefit was found in diseased animals under veterinary management.

2019 · Systematic review

Clinical effect of probiotics in prevention or treatment of gastrointestinal disease in dogs: a systematic review

Journal of Veterinary Internal Medicine

Scope. Screened 165 studies, including 17 in vivo canine trials, grading design quality and risk of bias; stool consistency was the most reported outcome.

Supports. Establishes stool consistency as the practical primary outcome for canine digestive research and the need for strain-level data.

Does not establish. Does not support a general probiotic efficacy claim in dogs — the authors found a very limited and possibly clinically unimportant effect, with moderate-to-high risk of bias throughout.

2019 · Controlled study

Effects on nutrient utilization and stool quality of Beagle dogs fed diets with beet pulp, cellulose and Miscanthus grass

Journal of Animal Science / Kansas State University

Scope. Replicated Latin square in 12 Beagles comparing three fibre sources at 10% inclusion with total faecal collection.

Supports. Quantifies the fibre trade-off directly: beet pulp raised dry matter and total dietary fibre digestibility and lowered wet faecal output versus cellulose and Miscanthus.

Does not establish. Does not demonstrate a clinical gut-health benefit; beet pulp also lowered crude protein digestibility and produced softer stools, in 12 healthy laboratory dogs at one inclusion level.

Primary source ↗

2017 · Controlled study

Evaluation of three hydration strategies in detection dogs working in a hot environment

Frontiers in Veterinary Science

Scope. Randomised cross-over field study in seven working dogs comparing plain water, flavoured oral electrolyte solution and subcutaneous fluids.

Supports. Shows flavoured electrolyte solution more than doubled voluntary fluid intake versus water, making palatability-driven intake a legitimate design objective.

Does not establish. Does not demonstrate any performance or thermoregulatory benefit — no effect was detected on body temperature or search performance.

Primary source ↗

2014 · Consensus recommendations

Nutrition for working and service dogs

Veterinary Clinics of North America: Small Animal Practice

Scope. Review of nutritional physiology across canine work types, covering dietary fat, glycogen repletion, protein and ageing working dogs.

Supports. The macronutrient design logic for work-type-specific formulation — higher fat for endurance, balanced macronutrients for sprint work, post-exercise carbohydrate for repeated efforts.

Does not establish. Does not rest on trial evidence for all work types; the authors state that studies for agility, field-trial and detection dogs are rare, so those recommendations are extrapolated.

Primary source ↗

2006 · Nutritional standard

Nutrient Requirements of Dogs and Cats

National Research Council / National Academies Press

Scope. Consensus requirements, adequate intakes and recommended allowances for every essential nutrient in dogs and cats, across life stages.

Supports. The quantitative floor and ceiling for formulating canine diets and complementary products.

Does not establish. Does not establish requirements, doses or efficacy for probiotics, prebiotics, postbiotics, glucosamine, collagen or any other non-essential ingredient.

Primary source ↗

2006 · Controlled study

Lifelong diet restriction and radiographic evidence of osteoarthritis of the hip joint in dogs

Journal of the American Veterinary Medical Association

Scope. Lifetime paired-littermate study in 48 Labrador Retrievers fed either ad libitum or 25% less of the same diet from eight weeks of age.

Supports. Establishes lifetime energy control as the best-evidenced nutritional lever on joint outcomes — median age at first radiographic osteoarthritis 12 years restricted versus 6 years control.

Does not establish. Does not test any supplement or functional ingredient, uses radiographic rather than pain endpoints, and studied one breed in a controlled colony.
