Is canned tuna safe for dogs to eat every day?

No, you should never feed your dog tuna daily. Tuna contains significantly higher levels of mercury compared to other fish like salmon or sardines. Regular consumption can lead to mercury buildup in your dog's system, potentially causing permanent damage to their nervous system and kidneys. Keep tuna as a rare treat, serving it no more than once or twice a month in small portions.

Which type of canned tuna is best for dogs?

The safest option is 'Canned Light Tuna' (usually Skipjack), as it has the lowest mercury content. Always choose tuna packed in spring water with 'No Salt Added.' Avoid tuna packed in oil, which can cause pancreatitis, and skip any varieties containing spices, garlic, or onions, as these are toxic to dogs.
