Only a small taste of plain, fully cooked langoustine tail meat is appropriate. No pet-specific safety article exists yet for langoustine specifically, so this guidance follows the same rules used for lobster, its closest relative.
Langoustine — also called Dublin Bay prawn or Norway lobster — is a slim, clawed crustacean related to lobster but much smaller. It is sold whole, frozen, or as peeled tail meat, and is common in European seafood dishes and "scampi" preparations.
Scampi dishes typically simmer the tail meat in garlic butter or a white wine sauce, and restaurant langoustine is often salted heavily. Both the garlic and the sodium are reasons to keep restaurant-style langoustine away from pets and offer only plain cooked tail meat instead.
Shells and tails are hard and sharp, so remove them completely before offering any langoustine to a pet.
