In principle, all fairDogs users must be of legal age. Unsuitable are people who cannot safely lead the dog due to low physical strength. The rule of thumb for this is: the dog must not be heavier than the human. Pensioners are allowed to have and walk suitable dogs with them indefinitely, as long as they can control the dog and it does not endanger them or others. The dog should not be able to escape from the house or premises if you only have the dog with you and do not take it for a run (someone else will then walk the dog) Children under the age of 14 are only allowed to walk dogs in the presence of adults - never alone, not even small dogs. The reason for this is other dogs in dog encounters. If their dog is attacked by another, children are not allowed to regulate dog fights. Listed dogs may only be walked by young people aged 16 and over. In some places people need permits to keep these dogs.
