Query: `(\"fish oil\" OR \"omega-3 fatty acid\" OR \"omega-3\") AND dog AND nutrition`. The cluster returns **1174** records in Europe PMC; 6 representative studies are extracted below.

Each study is traceable by PMID.\n\n## Studies\n- **PMID 41237493 (2026, American journal of veterinary research)** — *[Paraphrased derived summary — non-Open-Access source.]* Dog Aging Project (DAP) owner survey (2020–2022; 40,367 dogs): 52% (20,993) received supplements. Among supplemented dogs, omega-3 fatty acids (57%, 11,934) and joint supplements (56%, 11,810) were the most common. Dog demographic factors predicted supplement use more strongly than owner demographics.\n- **PMID 42071988 (2026, Animals : an open access journal from MDPI)** — *[CC BY — Open Access, verbatim with attribution.]* Advances in Functional Pet Food Research: Health-Driven Ingredients, Nutritional Targets and Evidence-Based Claims.. Functional pet food has grown rapidly, in line with the accelerated humanization of pets, growing attention to relations between diet and health, and mounting sustainability awareness.\n- **PMID 40253962 (2025, Preventive veterinary medicine)** — *[Paraphrased derived summary — non-Open-Access source.]* Cross-sectional study of 106 dogs on a standardized diet (young 2–5 yr vs senior ≥8 yr). Senior dogs were less active, more often house-confined, more regularly dewormed, and more likely fed pet-store/supermarket food. Bloodwork showed seniors had higher plasma globulin and platelets and lower albumin (consistent with chronic low-grade inflammation of aging), plus muscle loss, poorer coat, and lower lymphocytes (suggesting sarcopenia, malnutrition, immunosenescence). Dogs previously on omega-3–deficient diets had elevated plasma triglycerides.\n- **PMID 40723550 (2025, Animals : an open access journal from MDPI)** — *[CC BY — Open Access, verbatim with attribution.]* Experiences in Formulating Insect-Based Feeds: Selected Physicochemical Properties of Dog Food Containing Yellow Mealworm Meal.. Yellow mealworm (<i>Tenebrio molitor</i>) meal is a promising sustainable protein for pet food, yet its effect on nutrient balance and granule texture is incompletely defined.\n- **PMID 42245978 (2026, Frontiers in veterinary science)** — *[CC BY — Open Access, verbatim with attribution.]* Insights into the influence of dog and guardian demographics, nutrition, and relationship on raw feeding practices.. <h4>Introduction</h4>Raw meat-based diets (RMBD) are increasingly popular among dog guardians, yet the role of personal nutrition habits and pet-guardian relationships in their adoption remains unclear.\n- **PMID 41976013 (2026, Animals : an open access journal from MDPI)** — *[CC BY — Open Access, verbatim with attribution.]* Plant-Derived Functional Ingredients in Pet Nutrition: Phytochemical Classification, Mechanisms, Efficacy, and Application in Dogs and Cats.. This review classifies plant-derived functional ingredients in pet food according to phytochemical groups and application forms, including direct oral supplementation and incorporation into complete diets.\n\nSource text: `pdf-raw/evidence/europepmc_omega3_fish_oil_dog_2026-07-22.txt` (Europe PMC first-hand abstracts, pulled 2026-07-22).\n\n## License & attribution\n\nMixed licensing per COPYRIGHT_POLICY §3: Open Access (CC BY / CC BY-NC /\nCC BY-NC-ND) studies are reproduced verbatim with attribution under their specific\nCC license; non-Open-Access studies are paraphrased as derived fact summaries\n(numbers and proper nouns preserved, sentences rewritten).
