Tuna — Feed with caution
While plain, cooked tuna in moderation is generally safe for dogs, regular or large consumption, especially of canned tuna in oil or brine, can lead to health issues. High mercury levels in tuna are a concern for long-term health, and excessive salt or fat can cause gastrointestinal upset or pancreatitis.
TOXIC COMPOUND
Mercury, Sodium, Fat
Mercury bioaccumulates and is a neurotoxin; excessive sodium can lead to hypernatremia; high fat can trigger pancreatitis.
DOSE THRESHOLD
No specific safe threshold for mercury in tuna for dogs is established, but it should be fed sparingly. A few flakes of plain, cooked tuna occasionally is generally considered safe. Canned tuna in oil or brine should be avoided due to high fat and sodium.
