Can my dog eat Tuna?
Use caution
Occasional cooked tuna is fine — not as a regular food.
What this means
Tuna is not toxic to dogs but is high in mercury, which accumulates in the body over time. Occasional small amounts of plain cooked tuna are fine, but it should not be a regular part of the diet. Canned tuna in water (not oil) is preferable. Avoid tuna packed in brine.
Symptoms to watch for
Note for medium dogs (20–60 lbs)
A tablespoon occasionally — not more than once a week.
