Let thing be a pup don't chuck it work at a young age let it develope properly make training fun for it there will be moments where you want to kill the thing but the more effort you put in the more you get back simple really. As said stock break it. Working on retrieve can be done in your front room while your chilling out aswell as on walks. Like I said what you put in is what you get back. Nice looking pup all the best with it ??
