Some fish, like tuna, has high levels of mercury. If your dog eats too much food with mercury in it, it can get sick and possibly die.

Pollution from the ground and humans goes into the ocean. It gets in fish and other animals that live there. Heavy metals, like mercury and lead, go into the ocean this way too.

When a fish lives for a long time, it can have more heavy metal. This is because they eat mercury from every meal. Mercury cannot be destroyed so it stays in the fish's body.

Tuna are large fish that live for a long time. They eat lots of other small fish, and they eat the mercury inside those smaller fish.

Some kinds of tuna have more mercury than others. For example, skipjack tuna is not as big as albacore and has three times less mercury.

What to Do if My Dog Eats Tuna?

First of all, if you find out that your dog has eaten a little piece of tuna, then they will be ok. But if they eat more tuna or have been eating it often, then their body might be poisoned by high amounts of mercury.

So, firstly you need to determine the amount. If you notice that they have eaten it in larger quantities then take them to a vet right away!

If mercury poisoning is confirmed, your pet will be hospitalized. They will get fluids that are intravenous, antibiotics, and anti-inflammatory drugs. Your vet might also give them activated charcoal and chelation therapy. That could mean they will put something in their mouth so the mercury goes out of their body through urination or vomit.

Mercury is bad for dogs. It is hard to fix when it has done damage to their heart, kidneys, or nervous system. If they have mercury in them and it does something bad, they will not live a good life.

You should keep items with mercury out of your dog's reach!
