Quick answer: Dogs can eat a little tuna, preferably packed in water and unsalted, occasionally because of mercury.
Cats love tuna, but it should only be an occasional treat: too much unbalances the diet and builds up mercury.
What about other pets?
🐦 Birds (Not safe): Tuna is not recommended for birds, because of the salt and mercury.
🐹 Rodents and rabbits (Not safe): Rodents and rabbits should not eat tuna.
🐠 Fish (Not safe): Aquarium fish should eat only food made for their species; tuna is not part of their diet and can foul the water.
Benefits for your pet
- A source of protein and omega-3.
Risks and precautions
- Large fish like tuna accumulate mercury.
- Tuna in oil is fatty, and tuna in brine is very high in sodium.
- Cats can get hooked on the taste and start refusing their food.
How to offer tuna safely
- Choose tuna packed in water, with no added salt.
- Offer a teaspoon mixed into the food, a few times a month at most.
How much is OK?
Foods outside the main diet, like tuna, should only be treats. The general rule is that treats should not exceed 10% of daily calories — for small dogs and cats, that means very small portions. The first time, offer a little and watch for vomiting, diarrhea or itching over the next 24 hours.
