High shutter speed if the little scamp is charging around (shouldn't be a problem if the weekend is as bright as it's supposed to be), and if using a narrow aperture focus on the eyes for 'face shots'.
Get down to the puppy's level too. Shots from ground level will draw the viewer in more than shot from above when you'll effectively end up with nothing but 'plans' of the puppy!
Most of all, have fun!
