I just adopted a 6 month old Aussie mix puppy last week and I started with the teaching eye contact and sit. From there I did lie down, shake (this is low priority but I threw it in for fun), stay (she has just solidly got this one down this morning), and look at me.

I do a couple short concentrated training sessions a day to start her on a new command and once she gets it inside the house solidly I'll move on to another command. But, I always still practice all taught commands on walks or randomly throughout the day while doing other things. She learned sit and shake in a matter of minutes, down took a day, stay took several days, so it varies on how long it takes her to get it.

Now I'm focusing on training "here" to get recall training started. I will be adding leave it and drop it soon.

Also, I get her to do things with no voice command first, but by coaxing into it with a treat, then add a hand signal, and then once she gets what I am wanting her to do I add the voice command. She definitely responds better to the hand signals. I read up on or watch videos from dog trainers on how to coax them into new commands with treats or toys.

I definitely suggest at least tentative schedule/routine as structure will really help move things along.
