German Shepherds can be easy and alos hard to train. You can use treats, toys, and other items to motivate your German Shepherd to help them learn a command. German Shepherds work very well and they are known to be very hard workers. And as i said before German Shepherd cna be easy and hard to train, they are more likely to be easyer. If you are having trouble training your German Shepherd you can call a Dog trainer and have them help you, but it probley wont be that big of a problem to train your German shepherd. You can also try and get your German Shepherd to listen to your commands in words and motions. Both of them should work very well. REMEMBER everytime your GermanShepherd or any dog does the trick dont ALWAYS give them a treat because you need to be a good leader and show them that just because they have done this they will get a treat and they have to understand that they are not doing it for the treats they are doing it because their trainer told them too. That is all the training tips for now! Good luck!
