The birth of puppies is an exciting time. It’s beautiful to watch a mother care for her newborns, especially in the early stages of life.
Puppy Stages of Development
A newborn puppy is completely helpless and dependent upon her mother. The first week of a puppy’s life mainly about sleeping and eating so she will grow.
Puppies should remain with the mother and littermates until about age eight to 12 weeks. However, it is most crucial to have a mother during the first few weeks of life. A puppy that has been separated from her mother will need human intervention. Raising a newborn puppy takes a lot of time and intensive care. This is not quite the same thing as caring for a young puppy.

Puppies are born with closed eyes and ears. They cannot see and can hear very little, if at all. Yet they are able to make noise, which sounds like high pitched squealing. They have no teeth at birth and are unable to walk. Newborn puppies are incapable of urinating or defecating on their own. In addition, a newborn puppy cannot regulate her own body temperature.
Most newborn puppies are instinctively able to find their mother’s nipples and begin nursing right after they are born, or whelped. Once cleaned up (by mom or a helping human hand) they will crawl towards the mother’s warm belly, find the teats, and begin to suckle.
With proper food intake and mothering care, a newborn puppy should double her weight in the first week of her life.
Newborn puppies will spend about 90 percent of the time sleeping for the first few weeks of life. That’s more than 22 hours a day, but the sleep doesn’t happen all at once. Pups will nap on and off throughout the day and night, keeping warm with littermates and the mother’s body heat. In between naps, they spend the rest of the time eating and being groomed by mom. Newborn puppies eat about every two hours or more.
Because newborn puppies cannot see, hear, or walk, they do not have much exploring to do early on. The puppy’s world is all about mom, littermates, and the box they all sleep in.
Health and Care
During the first few weeks of a puppy’s life, the mother dog spends the majority of her time providing food and care. The mother keeps her puppies clean and nurses them. She licks the anus and genitals of each puppy to stimulate urination and defecation. During this time, humans can gently hold and pet the puppies as long as this does not seem to upset the mother dog. It’s more likely for human contact to be welcomed if those humans are part of the mother dog’s family.
In general, it’s best to let mom do her job and stick to just petting the puppies. However, there are situations where the mother is unwilling or unable to care for her pups. Or, mom might be doing a fine job, but one or more puppies are not growing properly. This is when human intervention is the only possible way to save the puppies. If you decide to care for an orphaned puppy, be prepared to spend most of your time with the puppy for the next few weeks.
Any time a puppy is not gaining weight well or becomes orphaned, that puppy should be taken to a vet as soon as possible to assess her health. Puppies can get very sick very quickly without proper care. When in doubt about the health of a puppy, do not delay the vet visit!
If the puppy was rejected by her mother, it may be due to a health issue detected by the mother. In the meantime, you will need to do your best to provide the care her mother would have.
- Create a warm environment for the puppy to sleep. A small box with blankets and a heating lamp is ideal. Keep the lamp at a fair distance so the environment does not overheat. A heating pad and blankets can also work, just make sure the heating pad is well-covered to prevent burns.
- Bottle feed a special puppy formula every 2-3 hours. You may be able to find puppy milk replacement at a pet food store or through your veterinarian. Do not feed puppies cow’s milk, as it does not provide adequate nutrition and it can cause digestive issues.
- Use a warm cloth or cotton ball to stimulate urination and defecation immediate after each meal. The amounts of urine and feces will be very tiny. A normal stool will be soft.
- Regularly massage the puppy’s body and clean the puppy as needed. Massage will mimic the feeling of the mother grooming, something experts believe is an integral part of development.
Food and Nutrition
In general, a newborn puppy gets all the nutrition she needs from her mother’s milk. The first milk made by the mother contains colostrum, a substance right in antibodies and growth factors. The can be absorbed by the puppies for the first day or two of life and provides some temporary immunity against whatever illnesses the mother has immunity against.
Be aware that commercial puppy formula will not provide colostrum. Bottle fed puppies that do not get colostrum are especially vulnerable to illness and may not thrive.
Newborn puppies will not have teeth for several weeks and are unable to digest puppy food. Do not introduce any kind of dog food until the puppies are ready to begin the weaning process, usually around 3-4 weeks of age, unless it is otherwise recommended by a veterinarian.
Training and Socialization
A newborn puppy is too young to go through any kind of training, but there may be some things you can do to get her used to people and her environment. If the mother permits it, handle the puppies regularly for a short time. Take care not to keep the pup away from mom for more than a few minutes. You can use the time to cuddle and pet the puppy, acquainting her with the smell and feel of humans and the environment.
Puppy Development: Stages from Birth to Two Years Old
To help puppies grow up happy and healthy, it’s important to be aware of what they need at each phase in their development. Here is a quick summary of the stages of puppy development, starting at birth up to two years old.
Neonatal stage and dependence on mother dog: birth to 2 weeks
From birth to two weeks, puppies are completely dependent on mom for food and care, such as keeping themselves clean. The senses of touch and taste are present at birth. Neonatal puppies have limited movement and are capable of only a slow crawl.
Transitional stage and development of senses and weaning: 2-4 weeks
From two to four weeks, puppies become aware of and interact with their litter mates as well as their mother. Their eyes open and their sight is well developed by five weeks. The senses of hearing and smell are developing; their baby teeth start emerging. During this stage, puppies begin to walk, bark and wag their tails. By the end of this period, puppies are able to eliminate without their mother’s stimulation.
Weaning from the mother also begins during this phase. At around three weeks, puppies should be started on solid food. Offer the puppies small amounts of soft food in a shallow dish. By the time the puppies are eight weeks old, they should be eating solid food and no longer nursing.
Training, vaccinations and socialization: 3-16 weeks
From four to six weeks, puppies continue to be influenced by their mother and litter mates. They learn to play, gaining needed social skills from litter mates, such as inhibited biting (biting to play, not to hurt). The puppies also learn the ins and outs of group structure and ranking within the group. Puppies become much more vocal during this period, with the appearance of play barking and growling.
At this point, if mom is aggressive or fearful of people, the puppies may be affected by her attitude. To socialize your puppies to humans, have a variety of people interacting with them — young (with supervision) and old, male and female. During the socialization period, it’s also very important to expose your puppy to other normal experiences, such as car rides, crate-training, vacuum-cleaning, ringing doorbells, and a variety of objects and sounds. Also, handling of the feet and body parts is a good thing for a puppy to experience at an early age.
Training and socialization can begin very early, from the beginning of this socialization period, but do not permanently separate a puppy from his mother and siblings before eight weeks of age. House-training can begin as early as five weeks, when puppies will follow their mother through a dog door or can be taken out for elimination lessons.
At approximately six weeks, puppies can begin in-home training. You should handle all parts of the puppy, introduce his first collar and lead, encourage him to come using his name, and reward him with praise and treats. At this age, you can also start training puppies with positive reinforcement methods: using a clicker, praise and rewards.
At about eight weeks, puppies start experiencing fear; everyday objects and experiences can alarm them. This is a perfectly normal reaction — it doesn’t mean that you will have a fearful dog.
You don’t want to socialize your puppies with other dogs and cats until the puppies have been vaccinated, since they may pick up diseases (such as parvo, distemper, and hepatitis) that can be fatal to puppies. In general, about a week after the second parvo/distemper vaccination, it is reasonably safe for your puppy to play with other similarly vaccinated puppies, in a class with a relationship-based trainer. Ask your veterinarian for information pertaining to your individual puppy and whether she or he knows of any parvo or distemper outbreaks in your area.
Puppies can socialize with other species of animals as well — horses, cats, whatever animals you would like your puppy to be comfortable around. Of course, you’ll need to use caution and make sure that the other animals are friendly.
Establishing hierarchy within the group: 4-6 months
During this period, puppies grow rapidly and you may notice daily changes. Even though puppies are very energetic, don’t exercise your puppy too much, since he can overdo it. Among themselves, puppies begin to use ranking in their group structure — that is, they start testing where they fit in. Puppies may experience another fear phase that lasts about a month and seems to come from nowhere. Again, this is a perfectly normal part of puppy development and is nothing to be alarmed about.
Adolescent stage and continued training and socialization: 6-12 months
Like most adolescents, puppies are very rambunctious, so continue the process of training and socializing your dog during this phase. Socialization and training are necessary if you want your puppy to be comfortable and act acceptably in public places such as dog parks and beaches, or anywhere that she will meet new dogs and new people.
Social maturity and ongoing training: 1-2 years
By this age, your dog has reached adulthood, but changes in social preferences and habits can occur up to two years of age. Ongoing training will ensure a respectful and fun relationship between your dog and all human family members, which makes having an animal in the family a daily pleasure.
