Newborn Puppy Care: The First Week
The puppies are here. The first week is warmth, milk and weights — a quiet routine with a short list of warning signs. This is what to do, what to watch, and when a newborn needs a vet fast.
Warmth: the first job
Newborns cannot regulate their own temperature — at all. Keep the whelping area around 85–90 °F (29–32 °C) for the first days (a heating pad on low under half the box, or a heat lamp at a safe distance, so puppies can crawl away from the heat as well as toward it). A chilled puppy feels cool to the touch, cries, and cannot digest milk properly — warm a cold puppy gradually against your body before offering any feed, never feed a cold puppy.
Nursing and colostrum
Puppies should nurse within the first hours: the first milk, colostrum, carries the mother's antibodies, and it is only absorbed well in roughly the first day. Watch that every puppy latches and sucks regularly — in a big litter, rotate the smallest puppies onto the fullest teats. The mother should be eating her puppy food in large amounts now, with constant fresh water; lactation is the most demanding work of her life.
Daily weights: your early-warning system
Weigh every puppy at the same time daily (the scale from the preparation checklist) and write it in the notebook with an ID for each puppy — a dot of nail polish or a colored collar works. Steady daily gain is the single best sign a puppy is thriving; a puppy who stalls or loses for two days has told you something before any other symptom will.
Fading puppy warning signs
Call the vet the same day if a puppy
Cries continuously or is restless and crawling away from the pile · feels cold and does not warm up · refuses to nurse or sucks weakly · loses weight two days running · has diarrhea, labored breathing, or is rejected and pushed aside by the mother repeatedly. Newborns decline fast — “fading puppy” situations are won by hours, not days.
Care for the mother
She needs the vet's after-check if anything was unusual about the whelping (a retained placenta, a very long labor). Watch for a hot, hard, painful mammary gland (mastitis) and for the restlessness, trembling or stiff gait of eclampsia — low calcium, a particular risk in small mothers nursing big litters, and a genuine emergency. Keep her food and water beside the box so she does not have to choose between eating and staying with the puppies.

Frequently asked questions
How often should newborn puppies nurse?
In the first week, every 1–2 hours around the clock — including overnight. Healthy puppies nurse vigorously, then sleep in a pile. A puppy who is consistently pushed aside, cries continuously, or misses feeds needs help and possibly a vet the same day.
How much weight should a newborn puppy gain?
Expect steady daily gain — roughly 5–10% of body weight per day as a working guide, after a possible small loss on day one. That is exactly why the daily weigh-in matters: two flat or falling days in a row is your earliest warning that something is wrong.
What temperature do newborn puppies need?
Warm — about 85–90 °F (29–32 °C) in the immediate whelping area for the first days, easing down across the first weeks. Puppies cannot regulate their own temperature at all in week one, and a chilled puppy cannot digest milk properly. Warmth first, then feeding.
