Teach as much as you can while she is very young, it is harder after they begin to test you. I would begin with learning her name and sit. The name part is easiest with two people. Stand about 5 ft apart with some nice smelling treats (I used turkey) call her name and have her run to you or your partner, treat her and give her loads of praise, then the other person does the same, a round robin back & forth for a good 5 min. Make it fun and do it often until you can do it without the treats. It's a fun game and they love it! Use the same method after she learns her name to teach "come".
Sit is also easy. Take a nice smelly treat, let her smell it and hold it over her head so that she looks up to see it. Once you have her attention, move it in front of her nose then push your hand back towards her ears, as she looks up at it she will instinctively sit to get a better look, say the word sit and treat. Make a big deal, praise and practice! When I was teaching Cruiser I did it as often as I could until he did it without treats. We still make him sit before dinner, before going out, while I put on his leash, etc. Reminders are always great!
After she learns sit you can work on down. Have her sit, stand in front of her, let her smell the treat, hold it in front of her nose and slowly lower it until it reaches the ground, as she follows it, pull it towards you and repeat the word "down", as she stretches for the treat she will lay down to get it, (they usually do a stretch & crawl type manuver that is pretty funny) once she is down treat and give her loads of praise, the more you praise and make it fun the more she will try to do it!
By 10 weeks we had taught Cruiser's name, sit, down, shake, high five, feet (wiping his feet before we go in) and had started on "mine and yours". He was very eager to please and did not even realize he was training!
