About the Irish Wolfhound

The Irish Wolfhound — the tallest of all dog breeds — was originally bred in ancient Ireland to hunt wolves and Irish elk, with references to the breed appearing in Roman records as early as 391 AD. Standing a minimum of 30–32 inches tall (many reach 34–35 inches) and weighing 105–180 pounds, these gentle giants have a rough, wiry coat in gray, brindle, red, black, white, and fawn. Despite nearly going extinct in the 19th century, dedicated breeders — most notably Captain George Augustus Graham — revived the breed using Great Dane, Scottish Deerhound, and Borzoi crosses.

Temperament & Personality

Irish Wolfhounds are remarkably gentle and easygoing despite their formidable size — they carry themselves with a quiet dignity that belies their ancient warrior heritage. They are affectionate and loyal with their families, typically good with children, and generally accepting of other dogs and even cats when raised together. Despite their history as fierce hunters, modern Irish Wolfhounds are too gentle and friendly to serve as effective guard dogs.

Pros

  • Gentle, calm temperament — one of the most easygoing of all giant breeds
  • Good with children and other pets — patient and tolerant despite their massive size
  • Relatively quiet dogs that rarely bark without cause
  • Wiry coat sheds minimally and requires only occasional brushing and hand-stripping

Cons

  • Heartbreakingly short lifespan — average of just 6–8 years, with many lost to heart disease
  • Extremely high risk of dilated cardiomyopathy, osteosarcoma, and bloat
  • Very expensive to own — giant-breed food, medications, and veterinary care add up quickly
  • Requires a home with ample space — not suited to apartment living due to sheer physical size

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.
