Can pets eat Tuna?

What Pet Owners Should Know About Tuna

Tuna falls under the seafood category in our pet food safety database. For dogs, tuna is rated as requires caution, with a recommended portion of small amounts occasionally. For cats, the same food is rated requires caution, with a suggested portion of very small amounts occasionally. Ratings in our database are anchored to veterinary toxicology references, ASPCA Animal Poison Control guidance, and peer-reviewed nutrition research, not anecdotal reports, so pet owners can make decisions based on the same evidence a vet would cite in clinic.

Dog- and cat-specific reactions to the same food can differ significantly because of metabolic differences between the two species. When properly prepared, tuna offers dogs measurable benefits, including omega-3 and protein. Cats can similarly benefit from omega-3. Known risks for dogs include high mercury and sodium in canned, which is why portion and preparation instructions matter more than the food itself. For cats, watch for mercury accumulation and nutritionally incomplete. When a pet food is rated caution or unsafe, the rating typically reflects either a compound that is marginally tolerated in small amounts, a preparation step (cooking, removing pits, peeling) that transforms risk, or a quantity threshold above which gastrointestinal distress or organ stress becomes likely.

This page links out to species-specific full guides for tuna covering warning signs, emergency steps, and cross-reference data. For cats, the symptoms to watch for are thiamine deficiency with chronic feeding. If your pet has consumed a large amount of any food rated caution or worse, the ASPCA Animal Poison Control hotline at 888-426-4435 operates 24/7.
