Stage 1: The Neonatal Period (0 to 2 Weeks)

The first two weeks of a newborn puppy is considered a neonatal period. In this stage, puppies are blind, deaf, and neurologically underdeveloped. So, they are entirely relying on their mother and spend most of the time sleeping or eating. Here you can also read about Best Roomba for Your Pet Hair

Newborn puppy’s body: 

  • Puppies can touch and taste.
  • Their eyes and ears are closed, so they cannot hear or see.
  • They can’t stand or support their body weight, but they can pull themselves towards their mother
  • Their eyes start to open at around ten to fourteen days.
  • They continue to grow rapidly, adding 5-10% of their body weight (see puppy growth chart here)

Stage 2 – The Transitional Period (2 to 4 Weeks)

The period two to three weeks after the puppy is born known as the transitional period. In this time, the puppy begins to finally open its eyes and starts gaining strength, and learns to walk. Puppies look extremely cute when they try to stand and walk. 

Around 5 to 10% they grow each day during these weeks and up until they are about eight weeks old. During this time, puppies will develop a sense of smell and hearing, and social skills. Their teeth start coming in, and they’ll even start to bark.                        

A lot is happening during the second stage of puppy development because the brain develops quickly. It’s a crucial time when they start using the bathroom on their own, just like plants and animals learn to take care of their own bodily needs.

Puppy’s body

  • Puppies can stand, sit up and even start walking.
  • They can wag their tails and start to respond to sound.
  • Puppies become much more active and stronger on their legs.

Stage 3 – The Socialization Period (4 to 12 Weeks)

This period is one of the important stages in your puppy’s life. Not only do they start to develop into adult dogs, but they also start to develop fundamental ideas about the world. That’s why this period is known as the Socialization period. 

Now, puppies are more aware of their surroundings and start really enjoying playtime. When your puppy is about seven weeks, you can start house-training. 

As per the vet guidelines, the true training “golden time” is from 9 to 12 weeks. The reason is that now your pup is actively working on social skills and paying attention to both people and littermates.

So, leverage this truly wondrous period and play and teach your puppy. It’s also imperative to socialize your little friend by introducing it to new people,  dogs, noises, and environments.

Puppy’s body:

  • Puppies can bark properly.
  • A small breed puppy may gain around 140 grams per week in weight, whereas a large breed puppy may put on around 9 to 10 kg per week.
  • At eight weeks, the puppy’s brain is curious and ready to grasp the information.

Stage 4 – The Ranking Period (3 to 6 Months)

From three to six months of the puppy’s growth is known as The Ranking Period or The Juvenile Period. This is the time where they start growing both physically and mentally. Therefore, you can consider this stage as the “pre-teen” years. 

You should be more careful about the environment at this stage. For example, if you have another pet in the home, your puppy will start to make friends or want to know them. Also, at this time, puppies get highly influenced by their human family. This means training and socialization are very important during this time. 

Some teething and chewing issues happen around this time. So, consult your vet if your puppy is facing any major difficulty. 

Puppy’s body

  • Teething and related chewing (and chewing issues!) occur.
  • Toilet training becomes much easier.
  • For small breeds, the growth plates are starting to close. 
  • At this stage or by the end of the fourth month, the medium to large breeds will reach about half their adult height.
  • Whereas the toy and small breeds almost complete their growth by the end of the sixth month. 

Stage 5 – The Adolescence Period (6 to 18 Months)

Just like humans, this time is considered as the teen period for dogs. This is because they start blooming and becoming an adult in this period. For most pet owners, this is the most annoying stage. 

Most adolescent puppies get easily distracted and more prone to testing boundaries, and which means they don’t follow your rules. To help curb wild behaviors, you will have to train them consistently, and you’ll also need lots of patience! 

After some time, you’ll know what to expect and at which times, so you can prepare yourself to deal with specific behaviors. This way, you can handle them positively, which will also encourage the kind of behavior you want.

When a puppy reaches puberty, the adolescence stage begins between six months to one year of age. The smaller the breed, the faster they grow or reach puberty. However, in larger breeds, it can start as late as 9 or 10 months.

Puppy body

  • A female puppy will come into season in the second half of her first year in which she can mate and have puppies. However, breeding at such a young age could harm your puppy.
  • Male dogs will also start showing an interest in females in this developmental stage. 
  • When your puppy reaches about seven months, his or her adult teeth will replace the milk teeth.
  • The adolescent puppy’s brain is fully developed and contains the learning capacity of an adult dog.
  • By the end of this stage, dogs will reach their full body weight and height.

Stage 6 – Adulthood (18 Months On)

Yes, this is the final stage in a puppy growth chart. So give a pat on your back because you’re a great dog owner, and now your pup has successfully crossed the wild teen phase and has moved on to adulthood.  

Most of the canines over the age of two will reach their full size and weight, and now they’re much more calm, relaxed, and predictable. Good for you! However, before stage 6 on the puppy growth chart, your pup had undergone a lot of developmental changes. This will ultimately build his personality, and your dog will be more disciplined and active.                               

You can calculate your puppy’s growth by calculators such as puppy weight calculators, dog weight calculators which are available online.
