Training your doberman is essential to a good relationship with your dog (and your neighbors). For some people going to a dog training class is just not practical or has limited effectiveness. In order to be successful at doberman training, it’s essential that you understand natural dog behaviour. Two of the best resources that I have found for training a doberman and that I often recommend to any dog owner are, leerburg.com and Caesar Milan.
Leerburg has articles with lots of training information and a great forum. Check it out especially if you’re having dominance or behavioural problems.
Then there’s Caesar Milan, better known as the Dog Whisperer. He has a popular series on the National Geographic Channel that should be watched by every dog owner. If you’ve never seen his show, I really recommend you buy the series DVD or look for them at your local library.
Either of these are a great resource for common issues such as doberman aggression or shyness.
