Can dogs eat mackerel?

Yes — cooked plain, no bones

Yes. Plain cooked or plain-tinned mackerel is a nutritious fish for dogs. Remove bones and avoid smoked varieties.

The full picture

Mackerel is another omega-3-rich fish that's great for dogs in moderation. It's higher in fat than some white fish so use in smaller portions for pancreatitis-prone dogs. Fresh mackerel should be fully cooked — never raw. Tinned mackerel in spring water or tomato sauce (no onion) is fine. Smoked mackerel is a hard no — too salty and sometimes contains preservatives. Always check for bones. Like sardines, a couple of times a week is great for skin, coat, and joints.
