Hes pretty smart,  doesnt listen for anything, but knows several human fooling tricks.
   Yest they are,there were bred to  be sufficient and think for themselves. Much like a terrier!
  Being a spitz breed ya they will be diggers,whether snow or dirt it's how they survive.
   You may not find a kill,it will likely eat small stuff like mouse or rat but will likely bring something like a rabbit back home to share!
 I also heard it helps to fool the dog into think he's training you.... 

    Clickers and treats together work sometimes,thats if the dog thinks you make a silly sound before you hand over food...... 

   They seem to be that smart!
