- PMID 41976013 (2026, Animals : an open access journal from MDPI) — 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. Polyphenols and plant extracts
- PMID 42344141 (2026, Frontiers in veterinary science) — Metabolic profiles show few differences in serum amino acid, one-carbon, and fatty acid compounds in dogs fed a plant-based ("vegan") or meat-based diet... Dogs are omnivores, not herbivores, and yet entirely plant-based diets are formulated to meet their current known nutrient recommendations. However, little is known about the metabolic effects of feeding diets containing no animal-derived
