Your puppy's first week is about safety and connection, not doing everything at once. Keep visitors and outings limited while your puppy learns the sights, sounds, and rhythm of the new home.
Offer frequent toilet opportunities, reward the behaviour you want, and expect a few accidents. Young puppies also need a great deal of sleep, so protect quiet nap time throughout the day.
Short, positive training moments are enough. Respond consistently, celebrate small wins, and allow your relationship to grow at your puppy's pace.
