I have had 3 males and 4 females what I have found is that there doesn't seem to be an :easier" sex. I have also had experiance with AKC breedings along with German breedings. The differance here sems to be that the German breedings seem to have more prey drive in relationship to cooperation. Both breedings have great trainability. So as you can see there is no good answer for you which sex question. If you have male dogs in the house adding a male may tend to start "marking" contests for this reason my wife has limited me to 1 male in the house at a time

Good Luck with your future pup DD's are a great breed.
