Since its already an adult it will be harder but just walk it alot of days like once everyday. You might have problems like the dog pulling you or tangling you. Dont let the dog get to far or he can choke on the leash.
German Shepherd, they are very smart. That's why the police use them so much
German Shepherd are clever enough to open a door and ring a dinner bell when hungry... ... ... Why not.
German Shepherd Dogs are easier to train. Rottweilers are known to be semi-aggresive and nippy during the training process. They are also very dominant.
every dog is different, but they usually train quite fast
Yup
No, but they are just very clever and if you don't train them they train you.
Toilet train him perhaps. type in'how to house train my dog' in google.
Absolutely not. You might even find it easier with an older puppy. Successful training at any age relies heavily on consistency in commands, so that the dog knows exactly what is/isn't allowed or expected of it.
You should be better at training! haha, by thorita.
yes but it will be very hard
Depends on you, as the owner. A German Shepherd would certainly be more loyal, going as far to die for its owner and is more popular. Beaucerons are much more rare. They both make good guard dogs but the German Shepherd is easier to train.
To train a GSD is easy. Get a book and read the methods for doing it, as long as you are firm a Shepherd learns very very quickly.
