The adolescence stage is in it's last faze now, it is fading into mature adulthood. This is also a crucial time to train you must enforce the rules, not through yelling, hitting or being cruel, but you are the pack leader so act like it, be confident, and remember the dog gets nothing for bad behavior BUT be kind. Whatever you teach and enforce in this stage (like in all the puppy stages as you may notice by now. It takes a lot to bring up a dog to live with, but it's fun) will be what your dog knows. Now it's never too late to train your dog, but it will come all the more easy for you if your dog learns manners growing up, it will give you less problems in the everyday and let you be in control and it's good to have an obedient adult dog, and more fun to play with too.
