Though tuna is rich in nutrients like protein, magnesium, B vitamins, and omega-3 fatty acids, it’s not recommended for your dog to eat. That’s because tuna – especially raw tuna – can lead to a number of health risks.
What Happens if a Dog Eats Tuna?
The main issue that can arise from eating tuna is the possibility of mercury poisoning. According to the American Kennel Club, fresh tuna contains higher levels of mercury than most other fish due to being larger and longer-living. One alternative would be to let your pup eat a fish that shouldn’t contain a concerning amount of mercury, like salmon or whitefish.
If your pup accidentally eats a little bit of tuna, he should be fine, but too much can lead to mercury poisoning. If you have a cat, you should also be cautious of your dog trying to snatch its food, as cat food can sometimes contain tuna in it. If you’re concerned that your dog may have eaten a large amount of tuna, the safest option would be to contact your veterinarian.
