About the Boston Terrier

The Boston Terrier — affectionately known as the "American Gentleman" — was developed in Boston, Massachusetts, in the late 1800s from crosses between English Bulldogs and white English Terriers. Standing 15–17 inches tall and weighing 12–25 pounds, they come in three weight classes and sport a compact, well-proportioned build with a distinctive tuxedo-like coat pattern. Their short, smooth coat appears in black-and-white, brindle-and-white, or seal-and-white — always with the characteristic white blaze, muzzle band, and chest marking.

Temperament & Personality

Boston Terriers are lively, intelligent, and brimming with personality — they have a wonderful sense of humor and seem to know exactly how to make their owners laugh. They are exceptionally friendly with people of all ages, including children and seniors, and typically get along well with other dogs and cats. Their moderate energy level and adaptable nature make them equally happy on a brisk walk or curled up on the couch.

Pros

  • Perfect apartment dog — compact size, moderate exercise needs, and minimal barking
  • Friendly and sociable with virtually everyone, including strangers and other pets
  • Low-maintenance coat requiring only occasional brushing
  • Highly adaptable temperament that suits first-time owners and experienced dog people alike

Cons

  • Brachycephalic (flat-faced) structure causes breathing difficulties, snoring, and heat intolerance
  • Prone to eye injuries and conditions like cataracts, cherry eye, and corneal ulcers
  • Can be stubborn about housetraining despite their intelligence
  • Susceptible to patellar luxation and spinal issues due to their compact build

Boston Terriers are the perfect blend of charm and companionship — find adoptable Boston Terriers on Puplister now.

About the Shih Tzu

The Shih Tzu — meaning "lion dog" in Mandarin — was bred for centuries within the walls of the Chinese imperial palace, likely from crosses between the Lhasa Apso and the Pekingese. These small, sturdy dogs stand 9 to 10.5 inches tall and weigh 9 to 16 pounds, with a slightly longer body than they are tall and a proud, flowing gait. Their luxurious double coat grows continuously and can reach floor length, coming in virtually every color and combination, with a distinctive chrysanthemum-like pattern on the face where hair grows in all directions.

Temperament & Personality

Shih Tzus are affectionate, outgoing, and delightfully playful — bred solely as companion dogs, they have centuries of experience perfecting the art of being a devoted lapdog. They are friendly with nearly everyone, including children, strangers, and other pets, making them one of the most sociable toy breeds available. Shih Tzus are happy, adaptable, and surprisingly sturdy for their size, with a mischievous charm that keeps their families entertained.

Pros

  • Exceptionally friendly and sociable with people of all ages and other animals
  • Low exercise requirements — short walks and indoor play satisfy their needs
  • Minimal shedding when coat is kept in a shorter "puppy clip"
  • Adaptable and content in apartments, condos, and any living situation

Cons

  • Long coat demands daily brushing or frequent professional grooming
  • Brachycephalic structure contributes to breathing issues and heat intolerance
  • Prone to eye problems (proptosis, corneal ulcers), ear infections, and dental disease
  • Can be stubborn about housetraining — patience and consistency are essential

A Shih Tzu's sole mission in life is to love and be loved — find yours waiting on Puplister today.
