Peer-reviewed research on canine food allergies, dietary sensitivities, and the immunology behind what your dog can — and cannot — eat.
We believe every sourcing decision should be backed by evidence, not marketing copy. This library curates published, peer-reviewed research from veterinary and immunology journals — the same studies that inform how we select and evaluate products. We update it regularly as new findings emerge.
Explains the signs, causes, and dietary solutions for dogs with sensitive stomachs. Covers common symptoms like vomiting, loose stools, and excessive gas, and recommends human-grade, limited-ingredient, gently-cooked foods over processed kibble — particularly for senior dogs and small breeds.
A systematic review estimating the prevalence of cutaneous adverse food reactions in dogs. Found that food hypersensitivity accounts for approximately 1–2% of all dermatological cases, with beef, dairy, and wheat among the most common triggers.
Identifies the specific protein fractions responsible for IgE-mediated reactions in dogs. Serum albumin and immunoglobulins were identified as major cross-reactive allergens across beef, chicken, and lamb — informing the case for novel protein diets.
Evaluates diagnostic methods for canine food adverse reactions. Concludes that the dietary elimination trial — using a hydrolyzed or novel protein diet for a minimum of 8 weeks — remains the gold standard for diagnosis, outperforming serum and intradermal testing.
Reviews the efficacy of hydrolyzed protein diets in managing cutaneous adverse food reactions. Finds that while hydrolyzed diets reduce allergenicity, residual intact proteins can still trigger reactions in highly sensitized dogs — supporting the case for limited-ingredient, single-protein formulations.
Characterizes gut microbiome dysbiosis in dogs with food-responsive enteropathy. Dogs with dietary sensitivities showed significantly reduced microbial diversity and altered Firmicutes-to-Bacteroidetes ratios, suggesting diet composition directly shapes gut immune tolerance.
Reviews the proposed association between grain-free, legume-heavy diets and dilated cardiomyopathy (DCM) in dogs. Concludes the relationship is not fully established and likely multifactorial, but recommends taurine monitoring in at-risk breeds on grain-free diets.
Demonstrates that commercially available serum IgE tests for food allergens in dogs have poor sensitivity and specificity. Reinforces that elimination diet trials are the only reliable diagnostic method — and that commercial allergy panels should not be used to guide dietary decisions.
Examines cross-reactive allergen epitopes shared between common protein sources. Finds significant cross-reactivity between beef and lamb, and between chicken and turkey — meaning dogs sensitized to one may react to the other, underscoring the importance of true novel protein selection.
