Newborn Puppy Care

A complete week-by-week guide to caring for newborn puppies during the critical first 4 weeks of life — covering feeding, warmth, weight tracking, and recognizing problems early.

Overview: The First 4 Weeks Are Critical

The neonatal period (birth to 4 weeks) is the most vulnerable time in a puppy's life. Newborn puppies are born blind, deaf, and completely dependent on their mother for warmth, nutrition, and even the ability to urinate and defecate. Mortality rates during the first two weeks can reach 20–30% even under experienced breeder care — and significantly higher without intervention when problems arise.

Whether you're supporting a nursing mother through her first litter, caring for orphaned puppies, or stepping in when the mother can't or won't nurse, understanding what's normal at each stage is essential. This guide covers the developmental milestones, care requirements, and warning signs for each of the first four weeks.

Week 1: Birth to 7 Days

Development

Eyes and ears completely sealed — puppies are blind and deaf
Sleep approximately 90% of the time
Only reflexes present: rooting (searching for nipple), suckling, and crawling
Cannot urinate or defecate without mother's stimulation (licking the genital area)
Cannot regulate body temperature — entirely dependent on mother and littermates
Umbilical cord dries and falls off by day 2–3

Critical Care Requirements

Temperature: Maintain 29–32°C (85–90°F) in the whelping area. Puppies cannot thermoregulate and will die from hypothermia if chilled.
Feeding: Nursing every 1–2 hours around the clock. Colostrum (first milk) in the first 24 hours provides essential antibodies.
Weight: Weigh each puppy daily at the same time. Expect 5–10% body weight gain per day. Birth weight should double by day 7–10.
Elimination: Mother stimulates elimination by licking. If hand-rearing, gently wipe the genital/anal area with a warm damp cotton ball after every feeding.
Handling: Minimal handling. Brief daily weighing is sufficient contact at this stage.

Week 2: Days 7–14

Development

Eyes begin opening: Day 10–14. The process is gradual — a slit first, then fully open over 1–2 days. Vision is blurry initially.
Still sleeping the majority of the time, but slightly more alert between feedings
Front legs becoming stronger — may begin lifting head and chest
Ears still sealed (will open in week 3)
Growth continues rapidly — should be noticeably larger than at birth

Care Requirements

Temperature: Can be reduced slightly to 27–29°C (80–85°F)
Feeding: Every 2–3 hours. Puppies are becoming more efficient nursers.
Weight: Continue daily weighing. Growth should remain steady.
Eyes: Never force eyes open. If discharge or swelling appears around sealed eyes, contact your vet immediately (possible neonatal ophthalmia).
Handling: Brief gentle handling (1–2 minutes daily) can begin for early neurological stimulation.

Week 3: Days 14–21

Development — A Transformative Week

Eyes fully open — vision improving daily but still limited
Ears opening — first responses to sound (startle reflex)
Standing and walking: First attempts to stand, followed by wobbly, uncoordinated walking
First teeth emerging: Tiny incisors begin breaking through the gums
Elimination: Beginning to urinate and defecate without mother's stimulation
Social awareness: Recognizing littermates, beginning to interact rather than just huddle
First tail wagging may appear

Care Requirements

Temperature: 24–27°C (75–80°F) — puppies generating more body heat now
Feeding: Still nursing every 3–4 hours. This is the beginning of the weaning window — some breeders introduce a gruel/mush at the very end of week 3.
Environment: Keep the whelping box clean. Puppies will begin eliminating on their own and moving around more.
Handling: Increase gentle handling to 3–5 minutes daily. Introduce varied textures and surfaces.

Week 4: Days 21–28

Development

Walking well: Coordination improving rapidly. Running attempts begin.
Interacting with littermates: Play fighting, chasing, vocalizing to each other
Teeth continuing to emerge: More incisors and canines appearing
Senses: Vision and hearing much improved. Responding to sights and sounds in the environment.
Mother spending time away: Natural behavior — she begins limiting nursing access, encouraging independence
Barking and growling during play

Care Requirements

Temperature: 21–24°C (70–75°F) — near room temperature is now appropriate
Weaning introduction: Begin offering puppy gruel (puppy food soaked in warm water or milk replacer to a mush consistency) 3–4 times daily. Puppies will still nurse but should be exploring solid food.
Environmental enrichment: Introduce safe toys, different surfaces (carpet, tile, grass), gentle sounds. This is the beginning of socialization.
Deworming: First deworming treatment typically given at 2–3 weeks and repeated at 4 weeks. Consult your vet for protocol.
Space: Puppies need more room now. Consider expanding the whelping area or adding a puppy pen attached to it.

Feeding Schedule: Normal Nursing vs. Bottle-Feeding Orphans

Whether puppies are nursing from their mother or being bottle-fed, the frequency and volume of feeds is critical to survival and healthy growth.

Week	Nursing Frequency	Bottle-Fed Amount
Week 1 (days 0–7)	Every 1–2 hours	~1 ml per 28g body weight per feeding
Week 2 (days 7–14)	Every 2–3 hours	Increase proportionally with weight gain
Week 3 (days 14–21)	Every 3–4 hours	Puppies more efficient; increase volume, extend intervals
Week 4 (days 21–28)	Every 3–4 hours + gruel offered	Begin supplementing with puppy gruel; reduce bottle feeds as food intake increases

Critical rules for bottle-feeding

Never use cow's milk — it causes severe diarrhea and lacks essential nutrients. Use commercial canine milk replacer only.
Feed belly-down — never on the back. Aspiration pneumonia (milk entering lungs) is rapidly fatal.
Warm formula to body temperature (~38°C / 100°F). Cold formula causes digestive distress and chilling.
Stimulate elimination after every feeding — gently wipe genital/anal area with warm damp cotton ball.
Burp gently after feeding by holding puppy upright against your chest and gently patting the back.

Newborn Puppy Weight Chart by Breed Size

Knowing the expected birth weight for your breed helps you identify underweight puppies immediately. All puppies should double their birth weight by days 7–10 regardless of breed size.

Breed Size	Birth Weight	Day 7–10 Target	Example Breeds
Small (adult <10 kg)	100–200 g	200–400 g	Chihuahua, Yorkie, Maltese
Medium (adult 10–25 kg)	200–350 g	400–700 g	Beagle, Cocker Spaniel, Border Collie
Large (adult 25–45 kg)	350–500 g	700–1000 g	Labrador, Golden Retriever, German Shepherd
Giant (adult >45 kg)	500–700 g	1000–1400 g	Great Dane, Mastiff, Saint Bernard

Weigh puppies at the same time each day using a kitchen scale accurate to at least 1 gram (for small breeds, 0.1 gram accuracy is ideal). Record weights in a log — a puppy that fails to gain weight for 24 hours, or that loses weight, requires immediate veterinary attention.

When the Mother Dog Won't Feed Her Puppies

A mother refusing to nurse is an emergency. Newborn puppies cannot survive more than a few hours without feeding in the first week. Act immediately while determining the cause.

Common Causes

Mastitis: Infection of the mammary glands. Signs: hard, hot, swollen, painful teats; may have discolored discharge. Requires veterinary treatment (antibiotics). Puppies should not nurse from infected glands.
Eclampsia (milk fever): Dangerously low blood calcium. Signs: trembling, panting, stiffness, inability to stand, seizures. This is a life-threatening emergency — immediate IV calcium from a vet is required. Most common in small breeds, first litters, and large litters.
Pain from delivery: C-section incision pain or trauma from a difficult birth can make the nursing position painful. Pain management with vet guidance helps.
Behavioral rejection: First-time mothers may be confused or anxious. Reduce stress, keep the environment calm and dark, and gently guide puppies to nurse while mother is lying down.
Illness: Retained placenta, uterine infection (metritis), or other post-partum complications can cause the mother to feel too ill to nurse.

Immediate Actions

Begin supplemental bottle-feeding immediately — even while arranging vet care
Keep puppies warm (29–32°C) — without nursing, they lose body heat rapidly
Contact your veterinarian — most causes of nursing refusal require medical treatment
If behavioral: try supervised nursing sessions with the mother on her side, in a calm dark room
Monitor puppy weights — any weight loss means current supplementation is insufficient

How the mother dog's nutritional needs change after birth — adequate nutrition during late pregnancy and lactation can prevent many of these complications.

Emergency Signs in Newborn Puppies

Neonatal puppies can deteriorate within hours. Know these warning signs and have your veterinarian's emergency number ready before the litter is born.

Seek veterinary care immediately if you observe:

Constant crying: Healthy neonatal puppies are usually quiet when warm and fed. Persistent crying almost always means the puppy is cold or hungry (or both).
Failure to gain weight: No weight gain for 24 hours, or any weight loss, indicates inadequate nutrition or illness.
Diarrhea: Can cause fatal dehydration within hours in a neonate. May indicate overfeeding, infection, or wrong formula.
Gasping or labored breathing: May indicate aspiration pneumonia (especially in bottle-fed puppies), congenital heart defects, or pneumonia.
Separated from litter: A puppy that crawls away and can't get back is at severe risk of hypothermia. Always count puppies.
Cold to the touch: A hypothermic puppy cannot digest milk. Warm SLOWLY (over 1–3 hours) before attempting to feed.
Refusal to nurse or suckle: The suckling reflex is the strongest drive a newborn has — its absence indicates serious illness.
Bloated or hard abdomen: May indicate constipation, overfeeding, or infection.

The concept of "fading puppy syndrome" describes neonates that decline and die despite appearing initially healthy. Causes include congenital defects, infections, insufficient maternal antibodies, and environmental factors. Early detection (daily weighing, observation) gives the best chance of saving affected puppies.

Frequently Asked Questions

Newborn puppies are born with their eyes completely sealed. Eyes begin opening between days 10 and 14 of life. The process is gradual — you may notice a slit at first, followed by full opening over 1–2 days. Vision remains blurry for another 1–2 weeks after opening. Never attempt to force a puppy's eyes open; this can cause permanent damage to the developing cornea.

In the first week of life, puppies nurse every 1–2 hours around the clock. During week 2, feeding frequency decreases to every 2–3 hours. By weeks 3–4, puppies nurse every 3–4 hours. If bottle-feeding orphaned puppies, follow the same schedule using canine milk replacer. Never use cow's milk — it causes severe diarrhea and nutritional deficiencies in puppies.

Use a commercial canine milk replacer (such as Esbilac or PetAg) and a puppy nursing bottle or syringe. Feed approximately 1 ml per 28 grams of body weight per feeding during the first week, increasing proportionally as the puppy grows. Feed with the puppy on its belly (never on its back — aspiration risk). Warm the formula to body temperature (about 38°C / 100°F). Stimulate elimination after each feeding by gently wiping the genital area with a warm damp cloth.

Newborn puppies cannot regulate their own body temperature. During week 1, the ambient temperature in the whelping area should be 29–32°C (85–90°F). Week 2: reduce to 27–29°C (80–85°F). Week 3: 24–27°C (75–80°F). Week 4: 21–24°C (70–75°F). Use a heating pad set on LOW under half the whelping box so puppies can move away if too warm. Monitor with a thermometer — hypothermia is the leading cause of neonatal puppy death.

Healthy newborn puppies should gain 5–10% of their body weight daily. They should double their birth weight by days 7–10. Weigh puppies at the same time each day using a kitchen scale accurate to 1 gram. Any puppy that fails to gain weight for 24 hours, or loses weight, needs immediate veterinary attention. Keep a written log for each puppy.

Emergency signs include: constant crying (usually indicates cold or hunger), failure to gain weight or weight loss, diarrhea, gasping or labored breathing, being separated from the litter (hypothermia risk), cold to the touch, refusal to nurse, and a bloated or hard abdomen. Neonatal puppies can decline within hours — contact your vet immediately if you notice any of these signs.

First, check for medical causes: mastitis (hard, hot, swollen mammary glands), eclampsia (calcium deficiency causing trembling, panting, stiffness — a veterinary emergency), or pain from a difficult delivery. If the mother is behaviorally rejecting the litter, keep her calm, reduce environmental stress, and guide puppies to nurse while supervising. If she still won't nurse, begin supplemental bottle-feeding immediately — puppies cannot survive more than a few hours without feeding in the first week.

Puppies begin attempting to stand around day 14–16, with wobbly, uncoordinated attempts at walking during week 3 (days 14–21). By week 4 (days 21–28), most puppies are walking reasonably well, though still clumsy. They will also begin playing with littermates, which helps develop motor coordination and social skills.
