Week 1 Newborn Puppy Care Guide: What to Expect and How to Support

The first week of a puppy’s life is the most critical period for survival. Newborn puppies are extremely vulnerable and rely completely on their mother and their environment. Small issues with temperature, feeding or hydration can escalate quickly, so understanding what is normal and what requires action is essential.

For breeders and owners, this stage is about close observation, early intervention and consistent care.

What Newborn Puppies Are Like in Week 1

During the first week, puppies are still developing basic functions.

At this stage

• Eyes and ears remain closed
  
• Puppies are unable to walk and can only crawl
  
• They rely on scent and touch to find their mother
  
• They cannot regulate body temperature
  
• They spend most of their time sleeping and feeding

Because of this, their care revolves around three key priorities, warmth, feeding and monitoring.

Day-by-Day Overview (Week 1)

Understanding how puppies progress through the first week helps you recognise what is normal.

• Day 1–2: Puppies should begin nursing quickly and remain mostly inactive. Colostrum intake during this time is critical for immunity.
  
• Day 3–4: Puppies may show slightly stronger crawling movements. Feeding becomes more consistent and weight gain should be noticeable.
  
• Day 5–7: Puppies appear stronger, with improved coordination and more purposeful movement towards the mother. Feeding behaviour should be well established. As development continues into the second week, puppies begin opening their eyes and becoming more responsive to their surroundings. Learn more about when puppies open their eyes and what to expect during development.
  

Any puppy that falls behind during this progression should be monitored closely.

   

Keeping Puppies Warm

Temperature control is one of the most important aspects of newborn care.

During week 1, the ideal environmental temperature is 29 to 32°C in the whelping area

Puppies that become chilled will stop feeding and quickly weaken.

Signs of chilling

• Cool to the touch
  
• Quiet or weak
  
• Huddling tightly

Signs of overheating

• Restlessness
• Spreading away from the litter
• Panting (rare but possible in older neonates)

Using appropriate heating & critical care equipment such as heat pads or heat lamps helps maintain a stable environment. Always allow space for puppies to move away from the heat source if needed.

If a puppy feels cool, warming must come first. See how to warm a cold puppy safely before attempting any feeding.

       

Feeding and Nutrition 

Feeding is the second critical pillar of care in the first week.

Puppies should

• Begin nursing within the first few hours after birth
  
• Feed every 2 to 3 hours
  
• Show a strong suckling reflex

Colostrum intake in the first 24 hours is especially important, as it provides essential antibodies.

Signs feeding is going well

• Puppies settle and sleep after feeding
  
• Full, rounded abdomens (not bloated)
  
• Steady daily weight gain

Warning signs

• Weak or absent suckling
  
• Crying after feeding
  
• Failure to settle

If support is needed, appropriate neonate puppy nutrition and feeding methods can be introduced. A milk feeding calculation guide helps ensure puppies receive the correct intake based on weight.

   

Daily Weight Monitoring

Daily weighing is one of the most reliable ways to track puppy health.

Puppies should gain weight every day, although it is common for them to lose a small amount of weight within the first 24 hours after birth.Lack of weight gain is often the first sign of a problem

Using a digital scale and recording results helps identify issues early. Even small changes can indicate that intervention is needed.

Normal Behaviour in Week 1

Healthy puppies in the first week will

• Sleep quietly between feeds
  
• Wake briefly to nurse
  
• Stay close together for warmth
  
• Make small noises, but not constant crying

A calm, settled litter is usually a good sign that conditions are appropriate.

Over the following week, puppies gradually become stronger and more responsive as early development progresses. Learn what changes to expect next in our guide on Week 2 Newborn Puppy Development.

    

Warning Signs to Watch For

Puppies can decline quickly, so early signs should never be ignored.

Watch for

• Constant crying or restlessness
  
• Weakness or reduced movement
  
• Poor feeding or inability to latch
  
• Failure to gain weight
  
• Cool body temperature

These signs may indicate dehydration, low blood sugar or fading puppy syndrome. You can also review signs of dehydration in puppies to help identify early issues.

When to Act Quickly

Early action can make a significant difference in outcomes.

Act promptly if

• A puppy has not fed for 4 to 6 hours
  
• There is no weight gain within 24 hours (minor weight loss in the first 24 hours after birth is common but pups should gin after this)
  
• The puppy feels cold or weak
  
• Crying is persistent and unsettled

If a puppy is weak, a small amount of Karo syrup or energy support may help stabilise temporarily, but warming and proper feeding are still essential.

In more serious cases, support using syringe, bottle & tube feeding may be required.

Daily Newborn Puppy Care Checklist

• Check warmth of the environment
  
• Observe feeding and behaviour
  
• Weigh each puppy
  
• Monitor hydration and strength
  
• Ensure the mother is attentive and feeding

This simple routine helps you stay ahead of potential problems.

The Mother’s Role in Week 1

The mother plays a critical role in the survival of the litter.

You should observe

• Regular nursing
  
• Cleaning and stimulation of puppies
  
• Calm, attentive behaviour

If the mother is restless, not feeding puppies or appears unwell, intervention may be required to support the litter.

     

Final Thoughts

The first week of a puppy’s life is all about stability, warmth, consistent feeding and close monitoring. Most problems can be managed successfully if they are recognised early and addressed quickly. If your puppy is still weak, not feeding well, or you’re unsure at any stage, it’s a good idea to check in with your veterinarian to make sure the right support is being provided. For more newborn puppy survival and care tips, see our full guide: How to Care for Newborn Puppies.
