#16 Adults are more hardy, so you can go on long excursions with them.

By the way, the activity of a mature dog is usually limited to walking, which is especially valuable for owners who do not have the opportunity to systematically train with a pet. The Leonberger is supposed to walk twice a day, for about an hour. Well, in the summer, given the breed's innate passion for water, the dog can be taken to the beach, allowing it to swim to its fullest. Just don't go swimming late at night. The coat must have time to dry before the Leonberger goes to bed. Otherwise - hello, unpleasant smell of dog, eczema, and other "joys".
