Stages of Puppy Development

Dogs are considered puppies from birth to one year of age and go through several puppy stages and development periods. A newborn puppy doesn’t look much like a dog and goes through different stages of puppy development during his first twelve weeks. However, each dog develops differently, with smaller dogs tending to mature earlier and some large breeds not physically mature before they are two years old.

Puppy at 0 to 2 Two Weeks – The Neonatal Stage

The puppies are blind and deaf. They don’t have teeth and can’t regulate their own body temperatures.

From birth, puppies are able to use their sense of smell and touch, which helps them root about the nest to find their mother’s scent-marked breasts. The first milk the mother produces is called colostrum. It is rich in antibodies that provide passive immunity and help protect the babies from disease  during these early weeks of life.

Expect puppies at this point to sleep almost constantly and their mother will take care of everything, keeping them warm, feeding them, and keeping them clean.

Puppy at 2 to 4 Weeks – The Transitional Stage

The second week of life brings great changes for the puppy. Ears and eyes sealed since birth begin to open during this period, ears at about two weeks and eyelids between ten to 16 days. They will start to respond to sounds, light, and movement around them.

This is also when your puppy will eliminate without their mother’s help and their teeth will start to come in.

You will also notice a puppy at this point starting to get more mobile, although they will still tend to crawl instead of walking. They do, however, have enough strength to stand up, but will stumble a lot.

A puppy in this stage will just be starting to recognize their siblings and mother. They may even take a lick of their mother’s food out of curiosity at this point but still don’t need more than mother’s milk.

Puppy at 3 to 4 Weeks – Awakening of Senses

At this point, a puppy develops various senses rapidly. They start to get fully alert and aware of their environment and may recognize you and other humans that are frequently around.

During this stage, you should take steps to avoid sudden changes or loud noises since negative occasions can affect development and the dog’s personality.

It is crucial that the puppy still stays with the mother at this point since they are learning ‘how to be a dog’, how to act themselves and how to interact with others of their species.

Puppy at 4 to 7 Weeks – Socialization Period

Once a puppy is around four weeks old, they start to learn the most important things in life related to social development. They will learn to not bite all the time and how to interact with their siblings.

Interactions with humans are especially important between five and seven weeks. This is also the time they will start to understand discipline thanks to their mother. She will start weaning her puppies and teaching them manners, like acknowledging she is in charge.

As the owner, you can start introducing food to your puppy when they are around four weeks old. Start small and begin to give them more food as the mother continues to wean them.

You should also continue handling the puppy every day. However, be sure not to separate them from their siblings or mother for over ten minutes each day, since this can lead to issues with training and socialization.

Dogs who are separated too soon may also be nervous and more likely to bark and bite. During this period, let the mother dog take care of discipline; you should not correct the dog for mouthing or housebreaking mistakes until later in life.

Beginning at four weeks of age, mom’s milk production begins to slow down just as the puppies’ energy needs increase. As the mother dog slowly weans her babies from nursing, they begin sampling solid food in earnest.

Puppies may be placed in new homes once they are eating well on their own. However, they will be better adjusted and make better pets by staying and interacting with litter mates and the Mom until they are at least eight weeks old–older generally is better.

Puppy at 8 to 12 Weeks – 2nd Socialization and Fearful Period

Although not all puppies go through a fearful period, most pass through a time where they are afraid or terrified of nearly everything, including items they used to be okay with.

To help ease them through this process, avoid traumatic events, loud voices, or harsh discipline. You should also make sure your pooch has plenty of human contact during this stage. If you want, you can start leash training and even teach simple commands such as sit, down, stay and come.

In terms of development, you will notice that your puppy can sleep through the whole night and starts to develop better control of their bowels and bladder.

During this time, you should make sure you don’t bring your dog to areas un-vaccinated or stray dogs frequent since they will be more prone to a fatal disease, such as an infection.

New outings should wait until they are fully vaccinated

Puppy at 3 to 4 Months – The Juvenile Stage

At this point in development, a puppy can be compared to a juvenile. They will be more independent and may ignore the basic commands that they know very well.

You may also notice your pup starting to test your authority by play biting or similar actions. You can stop this by saying “no bite” or “no” then ignoring them for a few minutes. You can also redirect your dog to a toy that they can bite.

You should keep playing with your puppy on a regular basis at this time, but don’t wrestle or play tug of war. Either can end up teaching your pooch that it is okay to fight with you and challenge your authority.

Puppy at 3 to 6 Months – The Ranking Period

When your puppy is between four and six months old, you should expect them to be somewhat bratty, showing more willfulness and independence.

They are more likely to test your limits and may try to show dominance over children or other family members. They begin to understand ranking, in terms of dominance and submission, and where they ‘stand in a pack.’

This is also when your dog will be teething, so give them chew toys to relieve pressure and pain.

This is when hormonal changes start to occur and is the ideal time to spay or neuter your pup.

Puppy at 6 to 18 Months – Adolescence

After six months, your pup is already in the final stage of puppy development but is still young. This is a fun and exciting time for your pooch since they will be learning, full of energy, and exuberant.

During this time, it is important to remember that even if your puppy now looks like a grown-up dog, they are still a puppy, at least in their mental capacity and emotional maturity.

Work to slowly increase training and other activities.Simply keep training them to ensure they interact in a non-aggressive and non-threatening way with other animals.

 

Provide socialization at the appropriate times and be sure to give your puppy plenty of social interactions with their siblings as well as humans and any other pets in your home.

Your dog should reach maturity at some point between one and two years old with plenty of variation based on breed,
