Can Dogs Eat Tuna?
⚠️ It depends. Small amounts of cooked tuna are safe occasionally, but mercury content is a concern.
Tuna can be safe for dogs in small, infrequent amounts, but it comes with significant concerns. The main issue is mercury content - tuna contains higher levels of mercury than most other fish. Regular consumption can lead to mercury poisoning. Additionally, raw tuna poses parasitic risks, and canned tuna often contains high sodium levels. While tuna provides protein and omega-3 fatty acids, there are safer fish options for dogs.

📋 What to Do
1. For one-time large consumption, monitor for immediate symptoms

🛡️ Prevention & Tips
Limit tuna to very rare treats, no more than once monthly. Choose canned tuna in water (not oil) with no added salt. Never feed raw tuna. Consider safer fish alternatives like salmon or sardines which have lower mercury levels. If using as a treat, tiny amounts are sufficient. Avoid albacore tuna which has higher mercury than skipjack.
