Can dogs eat 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.
If your dog ate more than a safe amount
Plain cooked crab is safe in small amounts. Crab shell fragments are sharp — call your vet if your dog has swallowed large pieces.

And while you're thinking about what's good for your dog, keeping on top of flea and parasite prevention is just as important as diet.
