Hi MyRottie, 6 months is a bit young to get that command down completely and training with treats is always a good idea at that age:D. Continue to use the treats and practice the command a couple times a day for short periods of time. At this age I would use treats ALL the time for now. They are very food motivated and will do well with it :D. You will be training for the next 3 years or so, so don't rush it, time and patience is the key. My 16 month old male still gets treats for training, not near as often but still gets rewarded for good behavior, nothing at all wrong with it. The DOWN command and the RECALL are probably your most difficult commands not to mention the DOWN being a very summisive postition ;). As time goes on when you think she has all the commands down she'll be a brat and decide she doesn't want to listen anymore or do the commands. It's not uncommon, that's why it takes a loooong time before we can say they're trained
. So hang in their, take your time and enjoy the different stages they go through.
