Handler sensitive, what does it mean? - Page 2

Thank you for your knowledgeable inputs and this is important for me since i've never come across DDR GSD before. I have a czech GSD myself, training for sport although czech bloodline is derived from DDR itself.. Just wondering how similar they are in temperament and personalities. I would like to know from those DDR GSD owners, what do you like and dislike about this DDR bloodline german shepherd? Anything in particular? Thanks.
