Name & attention
Say the name, reward eye contact.
The first months set patterns for life. Here's a calm, practical plan.

Take your puppy out first thing, after meals, naps and play, and before bed. Young puppies may need to go every 1 to 2 hours.
Use the same area and a cue word. Reward immediately when they go.
When you can't watch, use a crate or pen so there are fewer chances for accidents.
Use an enzymatic cleaner so the scent doesn't invite repeat accidents.
Most puppies take months to be fully reliable.
Mouthing is normal puppy behavior. Teach bite inhibition by redirecting to a toy and pausing play when teeth touch skin. Provide plenty of appropriate chews and rotate toys. Puppy-proof your home, and give a tired puppy things to do, since boredom drives most destruction.
Say the name, reward eye contact.
Lure, mark, reward, then add a cue.
Make it the best word ever: reward every time.
Reward calm on a mat; essential for rowhouse life.
