Can dogs eat tuna?

Quick takeaways about dogs and tuna

• Dogs can eat tuna, but only in moderation.
• Opt for tuna in water rather than brine or oil, and avoid tuna with added salt.
• Be mindful of mercury levels – tuna should only make up occasional treats.

Dogs can eat tuna, but it shouldn’t necessarily be a staple in their diet. Though it can be nutrient-rich, and full of essential fatty acids and protein, tuna can contain more harmful mercury than other fish, particularly when tinned.

Let’s reel in the facts about dogs and tuna.

 

Is tuna good for dogs?

Tuna is a good source of protein and omega-3 fatty acids, which can be beneficial for your dog’s skin and coat. However, the type of tuna matters, and it’s best not to feed it to your dog too often due to potential mercury exposure – which can cause digestive issues and kidney damage.

 

What types of tuna can dogs eat?

Here are a few rules to follow if feeding tuna to your dog:

• Opt for tuna in water with no added salt.
• Cook fresh tuna steaks thoroughly.
• Always check for bones, especially in fresh tuna, to prevent choking hazards.

Tinned tuna

Dogs can eat canned tuna, but it’s best served in water. Tuna in brine or oil can be too high in salt and fat.

Tuna mayo

We wouldn’t recommend feeding your dog tuna mixed with mayonnaise. The added fats and calories from mayo aren't suitable for your pup.

Tuna steak

Tuna steak can be a healthy treat for dogs when cooked plainly without added oils, seasonings, or sauces. Make sure it's fully cooked to avoid any risk of parasites.

Tuna pasta or tuna and sweetcorn

While the idea of sharing both with your dog might be tempting, it’s best to keep their diet simple and straightforward. Plain, cooked pasta in small quantities could be okay, but avoid adding sauces or spices. Sweetcorn is safe for dogs, but again, moderation is crucial.

 

How much tuna can dogs eat?

Moderation is key. Depending on the size of your dog, a small amount of tuna as an occasional treat is fine. Think a tablespoon for smaller dogs and up to a quarter cup for larger breeds, no more than once a week.

 

What are the risks of feeding tuna?

The primary concern with feeding dogs tuna is mercury exposure. Too much tuna can lead to mercury poisoning over time. Always keep tuna as a treat rather than a dietary staple.
