7 ingredients in this list are ones we hold sourced evidence on , and 1 of them is genuinely contested rather than merely unpopular online.

• Carrageenan · ingredient 14Worth knowingA seaweed-derived (Chondrus crispus) thickener and gelling agent used mainly in some wet and canned dog foods. Low-molecular-weight 'degraded' carrageenan (poligeenan) is inflammatory in lab-animal studies and is not permitted as a food additive, but food-grade undegraded carrageenan (E 407) is authorized by regulators; EFSA's 2018 re-evaluation kept only a temporary group ADI of 75 mg/kg body weight per day pending better data, and its specific effect in dogs is unresolved.
• Powdered Cellulose · ingredient 4NeutralPurified plant cell-wall fiber (typically from wood pulp) used as an insoluble-fiber source, bulking agent, and anti-caking aid, often in weight-management diets. It is not absorbed and is poorly fermentable, so it firms stool and dilutes calories but yields little of the short-chain fatty acids that more fermentable fibers produce; EFSA's 2018 re-evaluation found no safety concern and no need for a numerical ADI.
• Guar Gum · ingredient 7NeutralA soluble, viscous fiber from the guar bean used in small amounts to thicken and stabilize foods, mostly wet formulas. At higher dietary inclusion it can lower the digestibility of dry matter and protein in dogs, but it also produces metabolic effects such as reduced post-meal insulin and cholesterol; at the low levels used as a thickener these effects are minor.
• Xanthan Gum · ingredient 8NeutralA fermentation-derived polysaccharide used as a thickener and stabilizer, mainly in wet and gravy-style foods. EFSA's 2017 re-evaluation found no safety concern and concluded no numerical ADI was needed; direct studies in dogs are limited, but at the small amounts used it acts as a non-absorbed, largely fermentable fiber.
• Cassia Gum · ingredient 15NeutralA gelling agent made from the purified endosperm of Cassia seeds, used mainly in canned and wet foods. It is specifically authorized in the EU as a pet-food thickener: EFSA (2017) concluded that purified semi-refined cassia gum meeting the food-additive specification (under 0.5 mg anthraquinones/kg) is safe for dogs and cats up to the permitted feed level.
• Prebiotics (chicory root / inulin, FOS) · ingredient 16NeutralFermentable fibers (chicory-derived inulin and fructooligosaccharides) that feed colonic bacteria and are readily fermented to short-chain fatty acids in dogs. Feeding studies show they shift fecal microbiota composition and are well tolerated at typical inclusion levels, but clear health benefits beyond compositional change are not yet established.
