How to Serve Tuna Safely
A spoonful of water-packed tuna as a rare topper, never a daily meal. Choose light tuna over albacore and never feed raw tuna.

For most dogs, a small accidental taste is not an emergency. Watch for vomiting, diarrhea, or loss of appetite over the next 24 hours, keep fresh water available, and call your vet if symptoms appear — or sooner if your dog is very small, very young, or has existing health conditions.
