Detailed description
In Hamburg, dogs are generally required to be kept on a leash.
You can apply for an exemption from the leash requirement if you have passed the required obedience test with your dog with a recognized expert or have passed an equivalent test.
Exceptions for elderly and sick dogs are possible, provided you can present a corresponding certificate containing a veterinary assessment of your dog's behavior. Please note that the submitted certificate will be reviewed for plausibility by the official veterinary service.
Dangerous dogs according to the Dog Act cannot be exempted from the leash requirement.
