Can dogs eat crab?

Caution — plain cooked meat only

Plain cooked crab meat is safe in tiny amounts but very high in iodine and sodium. Shell is a hazard. Crab sticks are processed fish, not crab.

The full picture

Real crab meat — plain, cooked, fully shelled — is safe for dogs in small amounts. It provides protein, zinc, and omega-3. But crab is naturally high in sodium and iodine, and some dogs are allergic. The shell is a serious choking and injury risk — never let a dog chew crab shell. 'Crab sticks' sold in UK supermarkets aren't crab at all but processed whitefish (surimi) with flavouring, salt, and additives — treat these as 'processed meat' and keep portions very small. Crab in butter, Old Bay seasoning, or with lemon is not for dogs.
