6 ingredients in this list are ones we hold sourced evidence on , and 2 of them are genuinely contested rather than merely unpopular online.

• Peas · ingredient 7ContestedA pulse (legume) used in many grain-free foods as a plant protein and carbohydrate source. Peas are central to an open FDA investigation, begun in July 2018, into a possible link between diets high in peas, other pulses, and potatoes and canine dilated cardiomyopathy (DCM); 93% of reported products contained peas and/or lentils.
• Lentils · ingredient 8ContestedA pulse (legume) common in grain-free formulas as a protein and carbohydrate source. Lentils are named alongside peas in the FDA's open 2018 investigation into diet-associated canine DCM; the agency grouped 'peas and/or lentils,' which appeared in 93% of reported products.
• Mixed tocopherols (natural vitamin E) · ingredient 23Well supportedA blend of vitamin E forms (alpha-, beta-, gamma-, delta-tocopherol) used as a natural-source antioxidant to slow fat rancidity, commonly chosen as an alternative to synthetic preservatives. EFSA concluded that tocopherol-rich extracts are safe for all animal species and the consumer and are efficacious antioxidants in feed.
• Rosemary extract · ingredient 33Well supportedA plant-derived natural antioxidant (active compounds carnosic acid and carnosol) used to slow fat oxidation, frequently chosen as an alternative to synthetic preservatives. It is an authorized food antioxidant in the EU (E 392); JECFA established a temporary acceptable daily intake for rosemary extract expressed as carnosic acid plus carnosol.
• Chondroitin sulfate · ingredient 5NeutralA joint supplement usually combined with glucosamine. The same 2022 meta-analysis (Barbeau-Grégoire et al.) that examined glucosamine reported a marked non-effect of chondroitin-glucosamine nutraceuticals for osteoarthritis pain and advised against relying on them for canine and feline joint pain.
• Taurine (supplemental) · ingredient 25NeutralA sulfur amino acid that dogs can normally synthesize from methionine and cysteine, so it is not classically essential for them. However, some breeds (e.g., golden retrievers) and some diets are linked to low taurine status and dilated cardiomyopathy: an observational study (Ontiveros 2020) associated non-traditional, largely grain-free diets with taurine deficiency and DCM-consistent echocardiographic changes in golden retrievers, though causation and mechanism remain under investigation.
