Newborn Puppy: What Are The First 24 Hours Like?

The moment you’ve been eagerly anticipating has arrived: the birth of a newborn puppy. Whether you’re welcoming a puppy from your own dog or preparing for the arrival of a litter, the excitement is palpable. While there will be plenty of snuggles and adorable moments, don’t forget the responsibility that comes with it. Vet visits, ensuring proper nutrition, socializing the puppies, and eventually finding them loving homes are just the beginning.
But before all that, there’s the most important period—the first 24 hours. This initial window is vital for the puppies’ health and well-being, as well as the bonding process with their mother. Being prepared and armed with knowledge will help you confidently navigate this crucial time.
First 24 Hours With a Newborn Puppy
The first 24 hours with a newborn puppy are crucial for both the puppy’s development and the bond between the mother and her pups. Similar to human babies, puppies need a safe, warm, and nurturing environment to thrive during their first day of life. Creating a space that’s quiet, comfortable, and free from stress is essential for their early development.
To get things right, make sure the space for the mother and her puppies is already set up and prepared beforehand. The mother dog needs time to explore the designated area so that she feels safe and comfortable before the puppies are born.

The Importance of Bonding and Nutrition
Right after birth, the bonding process begins. It’s one of the most important things for the puppies. The first moments after birth will shape their sense of safety and security. Allowing the puppies to begin nursing immediately after birth is vital. This first milk, known as colostrum, is packed with antibodies and essential nutrients to help the puppies develop a strong immune system and grow strong.
For the first few hours of life, the puppies will instinctively begin to suckle. Breastfeeding establishes a strong emotional connection between the puppies and their mother. It’s crucial to allow the puppies uninterrupted access to their mother’s milk during this time to ensure they get all the nutrients they need.

It’s also important to keep a close eye on the puppies to ensure they’re healthy. Healthy puppies will show an active suckling reflex and should have a round, plump belly after nursing. However, not every puppy develops at the same pace, and some might need extra attention to catch up with their littermates.
Can You Leave Newborn Puppies Alone With Their Mom Overnight?
After the first few hours, it’s generally safe to leave the puppies alone with their mother overnight. Mother dogs are naturally equipped to take care of their puppies, providing them with warmth, nourishment, and safety.
While it’s usually safe to leave them alone, you must ensure their environment is secure. The whelping area should be free from any hazards, and the temperature should be kept at a comfortable 85-90°F (29.5-32°C) for the first few days. You can use a heat lamp if necessary to keep the puppies warm, but be careful not to overheat the area.

While the mother is naturally attentive, you should still keep an eye on things. If any puppies appear to be struggling during feedings or if the mother shows signs of distress, seek immediate veterinary help.
What Not To Do
As exciting as it is to welcome newborn puppies, there are several actions that could jeopardize their well-being, and knowing what not to do is just as important as knowing what to do:
- Avoid excessive handling of the puppies, especially in the first 24 hours. As tempting as it is to cuddle the newborn puppies, overhandling can cause stress for the mother and disrupt the vital bonding process.
- Never separate the puppies from their mother prematurely. The puppies need their mother’s milk for both nourishment and immunity during the first few weeks of life. Premature separation could result in nutritional deficiencies and increase the risk of infections.
- Refrain from introducing loud noises or unfamiliar scents into the whelping area. A quiet, calm environment is essential to prevent stress for both the mother and her puppies.

The first 24 hours with a newborn puppy are a critical and delicate time. To ensure a healthy start for both the puppies and the mother, it’s important to provide a safe, warm, and nurturing environment. Let the mother guide the care of her puppies while you monitor the situation closely for any signs of distress or health issues.
While it’s an exciting and magical experience to witness new life, patience, and attention to detail are key in setting the puppies up for a healthy start. Always consult with a veterinarian if you’re unsure about any aspect of the process, and remember that providing a secure, stress-free environment is the best thing you can do for your new furry family.
