Frequently asked questions
Why can't French Bulldogs eat tuna regularly?
Tuna contains relatively high mercury levels. Frequent consumption can lead to mercury accumulation over time, which is harmful. Occasional small amounts are fine.
Is canned tuna safe for dogs?
Only plain tuna in spring water — drain and rinse. Tuna in brine has too much salt. Tuna in oil has too much fat. Keep portions small and infrequent.
Is salmon better than tuna for dogs?
Yes — salmon is a better regular choice. It has higher omega-3 content and lower mercury levels than tuna.
Can puppies eat tuna?
Only a tiny amount very occasionally. Mercury is a particular concern for developing puppies — choose safer fish like salmon instead.
