Dog Health Questions: In the UK do you have to contact your local police to train a German Shepherd to protect you?

Im getting a German Shepherd I heard this from someone that you have to contact your local police to train a German Shepherd to be defensive/protective, or are you able to just do tht anyway at normal dog training classes?

Give me one good reason that German Shepherd specifically requires permission?

There is nothing wrong with training a dog to protect you, any dog. But be mindful you are responsible for your dog, and theres a thing called the compensation culture too!
Teaching a dog to chase and sieze is a different matter, I'm not sure of the procedure there, but security firms will have dogs that are allowed to bite if need be...that's probably whats meant here.
