Anyone can notice that the behavior of the dog once a major problem, in my house have 4 German Shepherd. You can only imagine what problems I had. My husband is more concerned about them, and as the average dog owners we had tried everything. so far I've heard a lot of advice that were good but not always solve all problems. I do not want to write a lot I think you can see my situation. I feel very lucky because my husband found a DVD course. Through our friends heard about Kody Clarke's DVD course. The good thing is that Kody is a professional coach and a different approach to training dogs. The course is divided into four weeks and requires only 10 minutes a day to train your dog. It's been 20 days since my husband keeps track of every step and our German Shepherds are much better behaved. DVD course is "The 4 week dog training course" or
"Kody Clarke Secrets". I'm not good in searching the internet but if I find something I'll try to let you know. In the meantime, if anyone looking I think its not a mistake if you decide to ask his help.
