Can Dogs Eat Tuna?
Safety Information
Small amounts of cooked or canned tuna are okay.
Important Notes
Use sparingly due to mercury content. Choose low-sodium varieties.
The Mercury Risk
- Mercury is a heavy metal that can accumulate in a dog's body over time, leading to mercury poisoning. The risk is higher with larger species of tuna, such as albacore, which have longer lifespans to accumulate mercury from their diet.
- Symptoms of mercury poisoning are severe and can include:
- Nervous system issues (tremors, loss of coordination)
- Vision problems
- Kidney damage
- Because of this risk, tuna should not be a regular part of your dog's diet.
How to Serve Tuna (If You Must)
If you do choose to offer your dog a taste of tuna, follow these rules strictly: 1. Choose the Right Kind: Opt for canned light tuna or skipjack, which are smaller fish and have lower mercury levels than albacore. 2. Packed in Water ONLY: Only use tuna that is packed in water. Never use tuna packed in oil (which adds unnecessary fat) or brine (which is excessively high in sodium). 3. Keep it Plain and Sparingly: Ensure there are no added salts or spices. A very small spoonful is plenty for a medium-sized dog as a rare treat. 4. Cooked, Not Raw: Like salmon, fresh tuna should be cooked thoroughly before being offered to a dog.
The Bottom Line
There are many safer fish options for dogs than tuna (like cooked salmon or sardines). While a tiny, occasional taste of the right kind of tuna is unlikely to cause immediate harm, the long-term risk of mercury accumulation makes it a food best avoided or minimized in your dog's diet.
General Feeding Guidelines
Introduce new foods gradually to monitor for allergic reactions or digestive issues.
Treats and human food should make up less than 10% of your dog's daily caloric intake.
Always consult with your veterinarian before making significant changes to your dog's diet, especially if your dog has pre-existing health conditions.
