What if my dog accidentally ate canned tuna?

Answered by Phillip Nicastro

If your dog accidentally ate canned tuna, there is no need to panic. Tuna is not inherently toxic to dogs, and a small amount is unlikely to cause any harm. However, it is important to keep in mind a few things to ensure your dog’s health and well-being.

1. Quantity: The amount of tuna consumed by your dog plays a significant role in determining whether it will cause any issues. A small amount, such as a bite or two, is generally safe. However, if your dog consumed a large portion or an entire can, it could lead to digestive issues.

2. Mercury Content: Tuna does contain mercury, but a single incident of your dog eating a small amount of tuna is unlikely to cause mercury poisoning. Mercury toxicity usually occurs with long-term exposure to high levels of mercury, such as regular consumption over a prolonged period.

3. Digestive Upset: Tuna, especially in large quantities, can cause digestive upset in some dogs. This may manifest as vomiting, diarrhea, or an upset stomach. If your dog experiences these symptoms, it is best to monitor them closely and consult your veterinarian if the symptoms persist or worsen.

4. Sodium Levels: Canned tuna often contains added salt, which can be harmful to dogs in excess. While a small amount is unlikely to cause issues, it’s important to be mindful of your dog’s overall sodium intake. High sodium levels can lead to dehydration and potentially contribute to heart and kidney problems in the long run.

5. Cat Food Containing Tuna: If you have both a dog and a cat, make sure your dog doesn’t have access to your cat’s food. Wet cat food, including many varieties that contain tuna, are formulated specifically for feline nutritional needs. Feeding your dog cat food regularly can lead to imbalances in their diet and potential health issues.

If your dog accidentally ate a significant amount of tuna or shows any concerning symptoms after consuming it, it is always best to consult your veterinarian. They can provide specific advice based on your dog’s individual health and circumstances.

While a small amount of tuna is generally safe for dogs, it’s important to monitor their intake and be cautious about excessive consumption. Keep an eye out for any digestive upset or unusual symptoms, and consult your vet if you have any concerns.
