DVDs by AnneMarie Silverton Unless you just happen to have the once-in-a-lifetime "perfect" dog, you have probably ecnountered a difficult problem or two at some level of training. Each of these DVDs addresses some of the common problems ecnountered in training for competition. AnnieMarie carefully explains the source of each problem, along with suggested solutions. (These DVDs regularly refer back to her standard comptetive obedience DVDs and you should view the corresponding standard DVD first.)
