Is Tuna Fish Safe for Dogs?
Tuna is safe for dogs in small amounts, but it’s not something they should eat tuna every day. The main reason for this is that tuna, particularly the bigger species, tends to have higher levels of mercury. As an occasional treat, tuna can be fine if you’re careful about how much you give.
Nutritional Benefits of Tuna for Dogs
Tuna is full of good stuff for dogs. It has lots of protein to keep their muscles strong and omega-3 fatty acids to make their coat shiny and skin healthy. Tuna also has vitamins like B12 and D and minerals like potassium and selenium, which help keep dogs healthy overall.
Risks Associated with Tuna for Dogs
However, there’s a flip side. Tuna can carry some risks, mainly due to mercury. Because tuna is a larger fish, it tends to have higher levels of mercury than other fish, which can be harmful to your dog if they eat it too often. Mercury poisoning can build up over time and lead to serious health problems, so it’s something to watch out for.

What Is Mercury Poisoning?
Mercury poisoning happens when too much mercury builds up in the body. Tuna and other big fish can contain mercury because of ocean pollution. When a dog eats too much of it, especially over time, they could develop mercury poisoning.
Symptoms of Mercury Poisoning in Dogs
If a dog is suffering from mercury poisoning, you might notice symptoms like loss of coordination, weakness, vomiting, and even neurological issues. In severe cases, it could be life-threatening. If you think your dog has eaten a lot of tuna and starts showing these signs, it’s important to get them checked out by a vet right away.
How Much Tuna Can Lead to Mercury Poisoning?
It’s hard to say exactly how much tuna would lead to mercury poisoning, as it depends on the size of your dog and how much tuna they eat. However, even a little bit of tuna too frequently can be risky. Stick to giving tuna as an occasional treat, and avoid making it a regular part of their diet.
Can Dogs Eat Canned Tuna Fish?

How to Safely Serve Tuna to Your Dog
Can dogs eat raw tuna?
When serving tuna to your dog, always make sure it’s cooked. Raw fish can carry parasites and bacteria that could harm your dog, so sticking with cooked tuna is safer.
Proper Serving Sizes for Dogs
When feeding your dog tuna, a small amount is plenty. For a small dog, a spoonful or two of cooked tuna mixed into their food occasionally is more than enough. Larger dogs can have a little more, but don’t go overboard. Always consult your vet if you’re unsure about portion sizes.
Alternatives to Tuna for Dogs
If you’re considering feeding fish to your dog but are concerned about mercury, there are safer choices. Fish like salmon, whitefish, and sardines (in moderation) are great alternatives. They have less mercury and offer the same nutritional benefits.
When Is Tuna Bad for Dogs?
Higher Levels of Mercury
As we’ve discussed, the biggest issue with tuna is its mercury content. Mercury poisoning can have serious consequences for dogs, so tuna should only be an occasional treat.
Salt Concentration and Other Additives
Another thing to consider is the salt content in tuna, especially canned tuna. High levels of salt aren’t good for dogs and can lead to dehydration or even sodium poisoning. Ensure any tuna you give your dog is low in salt and free from harmful additives.

Safe Fish Options for Dogs
Dogs can safely eat other fish like salmon, whitefish, and sardines. These fish have less mercury and are still a great way to get protein and omega-3 fatty acids.
