Did you know?
Herring played a central role in European history — the North Sea herring trade was the economic foundation of the Dutch Golden Age in the 17th century. The invention of a method to gut and salt herring at sea by Willem Beukelsz around 1380 allowed herring to be preserved and transported throughout Europe. Pickled herring became a dietary staple across Northern Europe and Scandinavia. The extreme salt concentration in pickled herring that makes it dangerous for dogs is a direct legacy of this medieval preservation technology.

What You Need to Know
Herring is a nutritious oily cold-water fish with excellent omega-3 content. The challenge is that herring as commonly sold is pickled smoked or brined — all containing sodium levels far too high for dogs. Fresh or frozen herring is much harder to find but when cooked plain provides excellent nutrition. Pickled herring is one of the worst fish preparations for dogs due to extreme sodium and acidic brine.
