5 Rules for Feeding Canned Tuna to Pets

Only feed tuna packed in water Avoid tuna packed in oil, broth, or any flavored liquid. These add unnecessary fat and calories that can upset your pet’s stomach.

Choose no-salt-added varieties Most canned tuna is high in sodium, which can cause dehydration and health issues—especially in cats. Rinse the tuna with water to reduce salt further.

Check for toxic seasonings Garlic and onion powder are common in flavored tuna and are toxic to both cats and dogs. Read the ingredient list carefully.

Keep portions small A spoonful as an occasional treat is fine. Do not make it a daily habit, as too much tuna can lead to nutritional imbalances or mercury exposure.

Avoid oil-packed tuna Sunflower or vegetable oil adds too much fat, which can cause pancreatitis in dogs and digestive upset in cats. Stick to water-packed only.
