The phrase sleeping through the night sets owners up to fail a young puppy, because it describes a bladder she does not yet own. A puppy of around eight to ten weeks typically manages two to three hours between toilet breaks, and that capacity grows week by week rather than arriving on a date. The realistic goal for the early weeks is not an unbroken night; it is a calm, predictable night in which she is taken out before she is desperate, learns that night trips are brief and dull, and gradually stretches the gaps as her body allows. Owners who plan for that progression sleep better too, because expected waking beats being woken by crying.
Build the Night Around Her Bladder, Not the Clock
End the evening in a way that empties the tank last thing: a final meal with time to digest before bed, water available but the last big drink not immediately before lights out, and a proper final toilet trip right before she is settled, waiting until she has actually been rather than assuming she has. Place her bed beside yours for the first weeks, or somewhere she can hear you breathing, because loneliness and toilet need arrive together at this age and proximity answers the loneliness half for free.
Then plan the breaks instead of dreading them. If she typically lasts about three hours, set yourself to take her out around that interval before she cries for it, or respond promptly when she stirs and fusses, which at this age usually means need rather than manipulation. As the weeks pass, watch her actual intervals lengthen, often to four hours, then five, and let her set the pace of stretching rather than imposing a schedule her body cannot meet. There is no fixed age by which every puppy sleeps through; size, individual development and evening routine all move the timeline, and a puppy progressing steadily is succeeding.
Keep Every Night Trip Boring
The trip itself is a lesson, so script it tightly: lead on, straight to her toilet spot, quiet praise when she goes, no play, no fuss, no lights blazing through the house, and straight back into her bed with the same settle cue. Dull trips teach her that night is for sleeping and toileting only, and that waking up does not purchase entertainment. Resist the temptation to feed, play or start the day at the four o'clock outing, however awake she seems; she will resettle far faster if the household treats the hour as night.
During the day, protect the sleep she needs in large amounts and keep evenings calm rather than exhausting her deliberately late at night, which tends to produce overtired, frantic behaviour rather than deep sleep. A consistent bedtime, a dim sleeping place and the same short sequence before lights out all help her body learn where night sits in the day.
Know What Is Not Normal
Crying that escalates across many nights despite prompt toilet trips, crying paired with straining, frequent tiny wees, diarrhoea, vomiting or a puppy who seems unwell should go to the vet rather than into a training plan. Equally, do not adopt leaving her to cry it out as a method: at this age crying is communication about real needs, and ignoring it teaches her only that night is frightening while risking the toilet accident she was trying to avoid. Patience here is genuinely short-term. Within weeks to a few months, typically, the planned breaks thin out, the intervals stretch, and one morning you realise she simply slept, because her body finally could.
