Why only in moderation for dogs
Tuna is not toxic to dogs and is rich in protein. It is a large predatory fish, though, and mercury builds up in its flesh over its life. A small piece now and then causes no problems, but tuna should not be a regular part of a dog's diet.
Canned tuna in oil is fatty, and tuna in brine or with seasoning is high in salt. Raw tuna, as in sushi, can carry parasites and bacteria. Plain cooked white fish is a better everyday choice.
How to give it
- Choose tuna in its own juice or spring water, without salt or seasoning, or cooked tuna.
- Drain off the liquid and give a small piece.
- Give it only now and then, not every day.
What to watch out for
- Tuna given regularly raises the amount of mercury in a dog's body.
- Tuna in oil can cause vomiting or diarrhoea.
- Tuna in brine or with seasoning is high in salt.
- Raw tuna can carry parasites and bacteria.
