The AKC lists tuna as acceptable in moderation, preferably cooked fresh tuna or canned tuna in water with no added salt. Large fish like tuna accumulate mercury, which can build up with frequent feeding.
Yes, in moderation
A little, occasionally. Plain tuna canned in water is safe for dogs as an occasional treat, but tuna contains mercury, so it shouldn't be a regular part of the diet. Avoid tuna in oil, brine or with seasoning.
This guide is general information, not a diagnosis. If your pet seems unwell, or you're worried, call your vet.
