Oh my thank you for the chuckle !
I hate to tell ya this But she is GONE . . . and now Adolescence sets in.

Just imagine your little sweet pup is now in her terrible 2/s stage or even worse the fierce fours. Fun STuff ....Worse thing you can do when a pup is on the run is to chase them ! Get your training under control and with some luck they will work.
Just because you have the treat doesn't mean that you always have to give it to her. A "good girl" or an pat the the head will sometimes be enough. Be sure that you are praising her for a good job done and correcting the naughty side of her while it is happening. If you find it later, its too late. She will have no idea why she is being corrected. I always go to the mess and as they follow I ask (who did this) 9 out of 10 times the guilty one will lower their head in shame.
I can help you with some of my own techniques that I have been very successful with training my four pups. I would strongly suggest leash training. You can find how to instructions on my site.You will find the link below in my signature. HOpe it helps !
