Detailed Safety Information
Tuna is not toxic to dogs or cats, but has higher mercury levels than most fish (especially albacore/white tuna). Small amounts occasionally are fine, but should not be a daily staple. Chronic heavy feeding can cause mercury bioaccumulation. Choose water-packed unsalted cans — avoid oil-packed or seasoned.
Moderate phosphorus — limit for kidney disease.
