Boston Terrier Puppy Development Stages

Boston Terrier Size

Birth – 2 Weeks

For a young puppy, this time frame is critical. Quite the opposite, in fact; they’re really delicate.

Their senses of sight and hearing aren’t fully formed until the first 10 days of life. During this time of development, their only activities are sleeping and eating.

They can’t even move around on all fours yet. They get their nutrition from their mother’s milk and have no teeth. As the 10-day mark approaches, they begin to show signs of opening their eyes.

They are at their period of greatest growth, yet this fragility makes them very vulnerable.

Most of us don’t get to see our pups at this stage as they remain with their mothers unless we serve as dog breeders or foster parents.

3 Weeks – 12 Weeks

We generally get our pup around this period!  Socializing your Boston Terrier puppy may shape its behavior for life.

Puppies are observant creatures. From weeks 3 to 4, they learn to regulate their bladders and bowels, so they realize they shouldn’t urinate where they sleep.

Good socialization changes your Boston Terrier. Expose them to new pets, people, and situations to reduce anxiety and skepticism.

If your dog is accustomed to human contact and dog relationships, dog park playing will be more enjoyable. Your dog will enjoy making new friends, getting plenty of pets, and playing for hours.

Your dog should also have alone time. If properly trained, your puppy won’t mind being home alone while you’re at work, so don’t feel terrible abandoning them.

4 Months – 9 Months

Boston Terriers misbehave like most young adults. Aggression is often linked to dominance over other canines, disobedience, and lack of socialization.  You can teach your dog despite these obstacles.

Spaying and neutering at six months are crucial because it reduces hostility, unplanned pregnancies, and marking.

Your puppy will chew on whatever he can get his hands on while his adult teeth grow. Quality time is crucial to connect with the pup, since you will be its main influence.

Boston Terriers mature sexually at this age. Dogs undergo dramatic hormonal changes, which vary in male and female pups.

Adult female canines go into heat twice a year for 2-3 weeks. Male canines are sexually active year-round but become the most fertile after one to two years.

This period requires training, fun, and exercise. This improves bone and muscular health.

10 Months – 18 Months

They’re going to keep expanding until they reach their full adult size. Along with maturing socially, they will become more active and fun.

Their proper conduct will need consistent instruction and exercise. They may start to exert greater personal agency and try out newfound freedom throughout the adolescent years.

Maintaining a regimen of training and discipline throughout this time is essential for raising dogs who mature into well-mannered adults.


About 12 to 14 months of age is the transitional period into maturity for Boston Terriers. Once a person reaches puberty, they stop physically growing and take on the traits of an adult.

Their childlike demeanor fades as they reach adulthood. But it doesn’t mean kids won’t appreciate exercise and movement.

How Big Do Boston Terriers Get?

Whether you bring home a large or tiny dog may be predicted in a few of ways.  Using their paws is one method.
