Zignature Original Catfish Formula with Probiotics

7 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 3ContestedA 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.
• Chickpeas (garbanzo beans) · ingredient 5ContestedA pulse (legume), also called garbanzo bean, used in grain-free foods for plant protein and carbohydrate. Chickpeas are among the pulses (with peas and lentils) cited in the FDA's open 2018 investigation into diet-associated canine DCM.
• Mixed tocopherols (natural vitamin E) · ingredient 17Well 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 19Well 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.
• Flaxseed (ALA omega-3) · ingredient 8NeutralA plant source of the short-chain omega-3 ALA. Dogs convert ALA to the long-chain omega-3s inefficiently: a controlled feeding study (Dunbar 2010) found flaxseed raised serum EPA but produced no measurable DHA.
• Taurine (supplemental) · ingredient 15NeutralA 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.
