Is a whole cup of plain cooked crab meat too much for a 5 kg dog?

Short answer

It is generally safe; a single cup of plain, cooked crab meat is not dangerous for a 5 kg dog. The main concern with that amount is stomach upset, as crab can be rich and harder to digest in larger portions. You should monitor your dog for vomiting or diarrhea over the next 24 hours. If no symptoms appear, offer water and continue normal care. Call your own vet if vomiting persists or your dog seems unusually lethargic.

Crab — Food safety facts

Cooked crab meat without shell or seasoning is safe. Shell splinters cause internal injuries.

Dogs and cats carry the same rating (Safe to share), so the notes below hold for either pet.

Crab is not toxic to dogs. The real limit is calories, fat and salt, so treat it as a small extra alongside the normal ration rather than a meal in itself.

There is no poisoning risk here, and the usual problem is simply eating too much at once: a heavy fat or salt load can bring on loose stools or a single vomit. Offer water, keep an eye on the pet for 24 hours, and do not induce vomiting.
