The first checks for each newborn puppy
When your dog has puppies at home, your job in the first days is observation, not handling for its own sake. Pick up each puppy briefly and gently, supporting the whole body, and check that the puppy feels warm, has a pink mouth, breathes easily without noise or effort, and wriggles with some strength when disturbed. Look over the belly button area for redness or discharge, check that the mouth closes fully, and confirm each puppy can find a teat and latch. A healthy newborn mostly sleeps and feeds in a cycle, twitching a little in sleep, and should not cry for long stretches.
Do the same brief check on the mother. She should be eating, drinking, passing urine and stools, and returning willingly to the box. Heavy bleeding, foul-smelling discharge, a hot swollen teat, trembling, or a mother who snaps at or abandons the litter are not watch-and-wait details at home.
Warmth, nursing, and weight tell you the most
Newborn puppies cannot regulate their own temperature, so a puppy who feels cool to the touch, lies apart from the litter, or cries while siblings sleep needs attention first. The whelping area should be warm and draft-free at the puppy level, with room for the mother to move off the heat if she gets too warm herself. Cold puppies should be warmed slowly against your body under a blanket before you try to feed them, because a chilled puppy nurses poorly.
Weigh each puppy at the same time each day and write the number down by an identifying mark or collar colour. Steady daily gain is the clearest home sign that nursing is working. A puppy who loses weight, stays flat while siblings gain, or has an empty, tucked belly after the others have fed may not be getting enough milk, may have trouble latching, or may need a veterinary check sooner rather than later.
What to watch in the mother and the box
Keep bedding clean and dry, and change it whenever it is soiled, because a damp, dirty box raises the risk of chilling and infection for puppies whose eyes and ears are still closed. Watch nursing from a distance for a full feed: you want to see puppies kneading, suckling steadily, and then settling with rounded bellies, not frantic rooting that never settles. Note which puppy feeds from which position if one is repeatedly displaced by stronger siblings, and give that smaller puppy first access at the next feed while you supervise.
Also track the mother between feeds. Reduced appetite for a brief period right after whelping can happen, but refusal to eat into the next day, vomiting, diarrhoea, straining, or restlessness away from the puppies deserves a prompt call to your veterinarian. She is recovering from birth while producing milk, so changes in her matter to the whole litter.
When a home check becomes a vet call
Contact your veterinarian the same day if any puppy is cold and does not warm up, cries persistently, fails to nurse, loses weight, has diarrhoea, shows discharge from the cord, or breathes with effort or an open mouth. Call urgently if a puppy is limp, unresponsive, or separated and deteriorating, or if the mother shows the warning signs above. Puppies decline quickly because they have so little reserve, so the threshold for calling about a newborn litter is deliberately low.
Bring your notes when you go: birth order if you know it, daily weights, which puppy is struggling, and how the mother has eaten and behaved. That timeline lets the veterinarian judge whether this is one weaker puppy, a feeding problem affecting several, or a problem in the mother herself. Keeping weights, nursing notes, and the mother's recovery details together in KinsLe through Pet Passport gives that first appointment a clear litter history instead of guesswork from memory.
