German Shepherds are hardworking pets who enjoy work. German Shepherds are typically obedient, biddable puppies that love to work. These dogs are dependable companions that have accompanied policemen and disabled persons all over the world. But wrong training can bring out the bad side of your pet. Dog troubles can include separation angst, aggression, timidity, fear biting, and unwelcome guarding conduct in the home. Most of those problems can be averted if a dog is properly socialised as a pup and if the owner maintains a position of authority.
