Can dogs eat it?

Can dogs eat tuna?

Only with care A little tinned tuna in spring water now and then is fine, but tuna is high in mercury, so it should not be a regular treat.

Why

Sources differ. AKC's tuna article says no, because tuna is high in mercury and dogs are sensitive to it, while AKC's wider food list and RSPCA Australia say a small amount of tinned tuna in water is fine as an occasional treat. A small amount will not cause mercury poisoning; the concern is regular feeding.

Signs to watch for

If your dog ate tuna

A bite from your plate needs nothing. If your dog has been eating tuna regularly and shows these signs, see your vet.

If your dog has eaten something toxic

Call your vet or the nearest emergency vet now. Do not wait for signs, and do not make your dog sick unless a vet tells you to. Take the packet with you.

How to give it safely

Tinned in spring water, not oil or brine, with no seasoning, and only occasionally. Salmon and white fish are better choices.

This is general guidance, your vet sets the actual schedule. Puppies, small dogs and dogs with a health condition can react to smaller amounts. Check with your own vet before changing what your dog eats.

Other foods people ask about

Bacon Only with care Best not. Bacon is very fatty and salty, and a large amount can trigger pancreatitis, which can be serious. Beef Yes, in moderation Yes. Plain, cooked, lean beef is a good protein treat. Skip seasoned burgers, raw meat and cooked bones. Chicken Yes, in moderation Yes. Plain cooked chicken with no bones or skin is a good protein treat. Never give cooked chicken bones. Cooked bones No, toxic No. Cooked bones splinter into sharp pieces that can choke a dog, cut the gut or cause a blockage. Never give them. Ham Only with care A small sliver now and then will not hurt most dogs, but ham is salty and fatty, so it is a poor regular treat. Lamb Yes, in moderation Yes. Plain cooked lamb with no bones, string, fat or seasoning is a good treat.
