Did you know?
Oysters are one of the few animals that filter the ocean for their food — a single adult oyster can filter up to 50 gallons of water per day. This filtering ability makes oysters both valuable for ocean health and potentially dangerous as concentrated repositories of waterborne toxins and bacteria. The zinc concentration in oysters is the highest of any food — a single oyster can contain up to 5mg of zinc. This exceptional zinc content makes oysters nutritionally valuable for humans but concerning for dogs with regular large consumption.

What You Need to Know
Cooked oysters in very small amounts are not toxic but their high zinc content makes regular large feeding a concern — zinc accumulates and causes toxicity at high levels. Raw oysters carry Vibrio contamination risk. Oysters are rarely fed to dogs intentionally and more often eaten accidentally when dogs access them at seafood events. Small amounts of plain cooked oysters are not an emergency.
