At what age should I really expect a wee one to get a command? i have a 12 week old pup, we have been working on sit for a little less then a week...she kinda sorta gets it. She kinda sorta comes when I call her name.....she REALLY comes when I shake the treat bag!

. I do realize it takes a while, but is she just too young...should I wait a month to really gear up the training and maybe slowly slide in little commands here and there? i mean when they are this youmg her attention span os that pf a gnat! LOL
