About Salmon

Salmon shows up on pet food labels as fresh salmon, salmon meal, or salmon oil, forms that differ in moisture and how much omega-3 they contribute.

Salmon is commonly used as a high-quality animal protein and rich source of omega‑3 fatty acids (EPA/DHA) in dog and cat foods, supporting skin and coat condition, joint and cognitive health, and overall muscle maintenance. While very nutritious, salmon can be an allergen for some pets and raw salmon may pose risks from parasites, thiaminase-related thiamine loss, and region-specific pathogens (e.g., salmon poisoning); owners should avoid feeding uncooked bones and consider sourcing to minimize contaminant and sustainability concerns.

Derived from: Cold-water fish (Salmo salar and related species), used as fresh fillet, rendered salmon meal, or extracted salmon oil
Primary role: Animal protein source and concentrated source of the long-chain omega-3 fatty acids EPA and DHA

Why it's used

Salmon and salmon oil are used to add EPA and DHA, the long-chain omega-3 fatty acids most associated in veterinary sources with skin barrier support and reduced inflammatory signaling; the Merck Veterinary Manual notes that essential fatty acid supplementation shows measurable improvement in roughly 20% of dogs and 50% of cats with allergic pruritus. Pets convert plant-based omega-3 (ALA) to DHA poorly, so cold-water fish sources like salmon are one of the more direct dietary routes to EPA/DHA.

Common concerns

Salmon poisoning disease Raw or undercooked salmon and trout from Pacific Northwest coastal waters and rivers can carry a fluke (Nanophyetus salmincola) infected with the bacterium Neorickettsia helminthoeca; dogs that ingest it can develop salmon poisoning disease, with signs appearing roughly a week after ingestion and, per Merck and university veterinary sources, high fatality without treatment. Cooking the fish eliminates this risk.
Thiaminase in raw fish Raw fish contains thiaminases, enzymes that break down thiamine (vitamin B1) and can contribute to thiamine deficiency with prolonged raw feeding; cooking or canning heat destroys thiaminase, which is why this is specific to raw or undercooked preparations.
Documented allergen frequency Fish is listed among the more commonly documented food allergens in cats (alongside beef and chicken) in veterinary dermatology reviews, though it is reported less frequently as a primary allergen in dogs.
Mercury and other contaminants Published testing of commercial pet foods has found fish-based formulas, including those listing salmon among top ingredients, associated with higher mercury levels than non-fish formulas; researchers note no single fish ingredient accounts for all cases, and sourcing and testing practices vary by manufacturer.

Also relevant

Farmed versus wild-caught sourcing can affect the fatty acid profile of salmon used in pet food, which is one reason some formulas specify sourcing on the label.
