The first week sets the pattern for everything after it. You do not need much gear, but you need the right gear in the right place before the puppy walks in.
Before the puppy arrives
Set the crate up where the family spends its evenings, not in a spare room. Put the water bowl where it will live. Pick the potty spot outside and walk to it once yourself so the route is automatic.
The first three nights
Expect crying. Put the crate beside your bed for the first nights and move it a little each night. Take the puppy out once in the night for the first week, then stretch the interval.
Gear that earns its place
A crate with a divider, a bed that fits inside it, a harness sized for growth, enzyme cleaner, and one slow feeder. Everything else can wait until you know your dog.
