I potty trained Nala by taking her out when I thought she'd have to go.

As puppies are very curious creatures, I had my eye on her 24/7, since she tried getting into everything.

Dogs, especially puppies, have to go potty after they've played and eaten. That's when they have to go at normal times. Playing gets the body going, as well as eating (duh.)

So, I'd take Nala out after she ate and after she got done playing with one of the family members or with me.

And since I had my eye on her 24/7 -- I'd correct her by saying "NO" and take her outside if she squated or began to squat.

If she went outside, i'd give her LOTS and LOTS of praise!
