As a potential parent or pup caregiver, it is vital to ask yourself key questions that will help prepare you to welcome, take care of, and nurture your puppies toward good health and full maturity. If this is the case, it is important that you first know what Boston Terrier newborn puppies look like.

What Do Boston Terrier Newborn Puppies Look Like?

Healthy newborn Boston Terrier puppies have pink and moist gums, mucous membranes, and a glossy, smooth coat. They have a small tail and short legs and their eyes are closed. In addition, they do not have any teeth, and their nails are very sharp.

Have a professional breeder inspect your puppies’ state of health and normalcy. You can also have a veterinarian on call to inform you of what to expect on your nursing journey. One sure way of monitoring the progress is by checking weight from birth on days 1,2,3,5 and 7. Typically, all your puppies should indicate a gradual weight gain.

Puppy Growth Stages That Your Boston Terrier Will Go Through

As your furry friend grows and develops into an adult, it will pass through five stages common to all other dog types. The stages include the following:

Neonatal Period (Birth to Two Weeks Old)

During the neonatal period, the puppy fully depends on its mother for nutrition and warmth. They make squeaking sounds when they are cold, and you can move them closer to their mother as they are unable to regulate their body temperature. They are fully furred when they are born, and they seem to like it when you rub their fur.

At two weeks old, their eyes will be open, although for some, they will be slightly open, and they will gradually open as they become older.

Transitional Period (Two to Three Weeks Old)

During the transitional period, your puppy is eager to explore as its ears and eyes are now open. You will notice that it will begin reacting to moving objects and respond to auditory cues. Its baby teeth start to appear too.

They will play amongst themselves and start to portray social behaviors such as growling and wagging their tails. Finally, they try to keep the sleeping area clean by moving away when they need to relieve themselves.

Socialization Period (Three to Twelve Weeks Old)

The socialization phase is where the dog learns from others how to act like other dogs. This includes its very littermates. They thus begin to explore their social boundaries, learn how to communicate, and play with other dogs effectively. Moreso, they start to gain mastery over their physical coordination skills.

Their hind legs catch up with their front legs, and they start taking their first steps, which tend to be wobbly at first. You should also begin to brush their hair at this stage. The hair can also be trimmed, and their nails will have grown to a level where you need to clip them. Unless it gets dirty, you can avoid giving it a bath at this stage.

They are ready to get vaccinated and weaned from their mothers’ milk to more solid foods at six to eight weeks. At ten to twelve months, they can get their next vaccination. Some socialization opportunities for your dog include:

  • People
  • Places and environments
  • Animals
  • Alone time
  • Noises

Juvenile/ Ranking Period (Three to Six Months)

When this breed gets to 3 to 6 months of age, this is a period that closely relates to the “teenage phase” in humans and is called the juvenile or ranking period in dogs. It is here that its adult teeth start to appear, allowing the pup to eat more solid foods than before. You can talk to your vet to know the foods that are appropriate for you to give during this period.

The dog, now grown-up, reaches sexual maturity and starts showing sexual interest. The female dogs experience their first heat cycle while their male counterparts begin to show interest in them.

Adolescent Period (Approximately Six to Eighteen Months of Age)

The adolescent period signals their arrival into young adulthood. Their bodies are muscular, and their heads have a square-like appearance, with their eyes having some kind of shine to them. Their coats also have a reddish tint when they are in the sun, and their ears are pointy.

This breed tends to be a bit naughty, with energy levels getting to an all-time high. They will tend to display low obedience to your commands and show aggressive behaviors, especially towards dogs of the opposite sex.

Related Questions

Here are some questions that you may also be asking yourself. 

What Is the Rarest Color of a Boston Terrier?

The rarest color for a Boston Terrier is albino, much like the albinos in all other animals. This is different from the normal color white because, in this case, the absence of melanin pigmentation in the skin accounts for the lack of color. The condition comes from the dog having two copies of the merle gene.

How Helpless Are Boston Terrier Newborn Pups?

Boston Terrier newborn pups are not entirely helpless. This is because they can be able to drag themselves closer to their mother. However, they rely on their mother for most of their needs, such as warmth, nutrition, and grooming, from when they are born until they are about four to five weeks old. 

Are Boston Terriers Born With a Full Tail?

Yes, Boston Terriers are born with a full tail. However, a majority are born with bobbed tails that are naturally quite short. This kind of tail is so short that it looks like it is cut. Interestingly this is not an abnormality and is actually the standard for this breed.


Most people find puppies cute from the time they are born to the time they are becoming adults. This is because, at this time, their fur is soft, their nose is tiny, and you just want to hold them all the time. Be sure you take good care of them by providing warmth, food, discipline, positive regard, and proper socialization. If your dog gets all of the above, it will grow into a healthy and happy doggie.
