With her regal bearing, alert expression, and devoted temperament, the Doberman is an impressive dog. Dobermans are reserved with strangers but are goofy and affectionate with their families. The Doberman was bred by a tax collector to protect him on his rounds as well as serve as his constant companion. For this reason, the Doberman owner has an edge in leash training, since Dobermans were bred to stay with their owner. On the other hand, since Dobermans were bred to protect, it is very important that yours is well socialized, especially while on-leash, so that she doesn't develop leash aggression.
While your Doberman was bred to stay with you, she was also bred to go all day. Dobermans are active dogs who require plenty of exercise to stay happy and calm and perform well. If your Doberman is bursting to run when you are trying to leash train her, you will find training much more difficult. Make sure your Doberman is well exercised and calm before beginning leash training. Even if you think she is worn out, it is helpful to do leash training at a bit of a jog at first until she gets the idea.
Your Doberman is a sensitive dog that will not respond well to harsh handling. Use a chest clip harness or a head halter to prevent damage to your Doberman's delicate neck, and motivate with toys, treats, and your affection. Begin training when your Doberman is well exercised but not exhausted, calm but not tired. Make sure you wear sensible shoes and are prepared to do at least some training at a bit of a jog.
