Claims (C1 — verbatim substrings of source_file)
- PMID 41295744 — Role of Diet as a Predisposing Factor for Dilated Cardiomyopathy in Dogs: A Narrative Review (Vet Sci, 2025). Abstract (opening): In 2018, the Food and Drug Administration (FDA) reported cases of dilated cardiomyopathy (DCM) in dogs, including breeds without known genetic predisposition, fed diets containing a high proportion of legumes or potatoes, many labeled grain-free. Despite concerns, grain-free diets remain increasingly popular. *[CC BY — Open Access, verbatim with attribution.]*
- PMID 41472100 — Preliminary Analysis of Intestinal Microbiota in Golden Retrievers Prone to Dilated Cardiomyopathy Due to Taurine Deficiency (Vet Sci, 2025). Abstract (opening): Taurine plays a key role in cardiovascular and gastrointestinal health in dogs and may be deficient in some predisposed breeds despite consuming complete petfood. This study aimed to explore potential associations between serum taurine concentration and gut microbiota composition in clinically healthy Golden Retrievers, a breed predisposed to taurine deficiency-associated dilated cardiomyopathy. *[CC BY — Open Access, verbatim with attribution.]*
- PMID 40941272 — Determination of Retinol, Cholecalciferol, α-Tocopherol and Phylloquinone Levels in Dogs with Dilated Cardiomyopathy: A Preliminary Study (Animals (Basel), 2025). Abstract (opening): Lipid-soluble vitamins are essential micronutrients that play a vital role in processes such as growth, reproduction, immune regulation, antioxidant defense, anti-inflammatory response and cardiovascular health. This study aimed to evaluate the plasma levels of retinol, cholecalciferol, α-tocopherol and phylloquinone in dogs with dilated cardiomyopathy (DCM). *[CC BY — Open Access, verbatim with attribution.]*
- PMID 41689959 — *[Paraphrased derived summary — non-Open-Access source.]* A 2026 JAVMA study compared dogs with DCM eating hydrolyzed versus nonhydrolyzed protein diets and characterized clinical and echocardiographic indices in those eating hydrolyzed diets; methods retrospectively reviewed records of DCM-diagnosed dogs from May 2018 to October 2023. The excerpt is cut off before the comparison results.
- PMID 41817417 — *[Paraphrased derived summary — non-Open-Access source.]* A 2026 Beagle study linked diet-induced dilated cardiomyopathy (DCM) to grain-free, pea-containing diets (possibly via increased oligosaccharides), and—because human heart failure associates with reduced cerebral blood flow and cognitive decline—explored whether a similar heart–brain association appears in dogs; the excerpt is cut off before results.
