Did you know?
Atlantic mackerel travel in massive schools that can contain billions of fish moving in coordinated formations. Mackerel are among the fastest fish in the ocean reaching speeds of up to 5.5 miles per hour sustained swimming. The high fat content of mackerel — which makes it nutritionally valuable but requires portion control for dogs — is directly related to their active lifestyle. Mackerel must swim continuously to breathe as they lack the ability to pump water over their gills while stationary.

What You Need to Know
Mackerel is an oily cold-water fish with excellent omega-3 content similar to salmon. The high fat content means portion control is important — too much causes digestive upset. Canned mackerel in spring water without added salt is safer than fresh for convenience. Canned in brine or oil is unsuitable. Dogs prone to urate bladder stones should avoid high-purine fish including mackerel.
