If you have a dog, it must be registered with the municipal administration where you live.
The municipal administration levies an annual charge for each dog.
In addition, electronic identification is compulsory for all dogs within the territory of the Grand Duchy of Luxembourg.
You should note that special rules exist regarding dogs that are likely to be dangerous.
Consult the Citizens' portal for details about 'Arranging for dog identification and registration' (in French and German).
The portal also provides information about places and situations in which your dog must be kept on a leash.
