About the Saint Bernard

The Saint Bernard originated in the Swiss Alps at the Great St. Bernard Hospice, where monks bred these massive dogs for over 1,000 years to locate and rescue travelers lost in snowstorms along the treacherous mountain pass. Males typically stand 28 to 30 inches tall and weigh 140 to 180 pounds, though individuals exceeding 200 pounds are not uncommon. Their coat comes in two varieties — short-haired (smooth) and long-haired (rough) — both in white with red, mahogany, brindle, or brown markings.

Temperament & Personality

Saint Bernards are gentle, patient, and extraordinarily tolerant — their legendary devotion to humans extends to being remarkably careful and nurturing around children despite their massive size. They are friendly with strangers, other dogs, and household pets, possessing a calm, unflappable demeanor that makes them wonderful therapy dogs. While not aggressive, their sheer size and deep bark are often enough to deter unwanted visitors.

Pros

  • Exceptionally gentle and patient — one of the best giant breeds for families with children
  • Calm, low-energy indoor demeanor despite enormous size
  • Friendly and non-aggressive toward people and other animals
  • Imposing presence provides natural deterrent without guard training

Cons

  • Legendary drooling — especially the loose-lipped, heavy-jowled individuals
  • Short lifespan of 8 to 10 years, with some living even less
  • Prone to hip and elbow dysplasia, bloat, osteosarcoma, and dilated cardiomyopathy
  • Enormous food costs and substantial space requirements for comfortable living

Few breeds embody devotion quite like the Saint Bernard — find one in need of a loving home on Puplister.

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.
