About the Cairn Terrier

The Cairn Terrier is one of Scotland's oldest working terrier breeds, originally developed in the Scottish Highlands and Islands to root out foxes, badgers, and other vermin from rock cairns and burrows. Standing 9.5–10 inches tall and weighing 13–14 pounds, the Cairn is a small but hardy dog with a wide head, compact body, and sturdy legs built for digging. Their weather-resistant double coat — a harsh, shaggy outer coat over a soft undercoat — comes in cream, wheaten, red, sandy, gray, and brindle, and requires regular brushing and periodic hand-stripping.

Temperament & Personality

Cairn Terriers are spirited, independent, and fearlessly curious — they approach the world with a terrier's characteristic boldness and an irrepressible zest for life. They are affectionate and loyal with their families, good with older children, and adaptable to various living situations. However, they retain strong prey drive and digging instincts, and they can be assertive with other dogs despite their small size — they seem entirely unaware of how tiny they actually are.

Pros

  • Hardy, long-lived breed with a lifespan of 13–15 years
  • Adaptable to apartment living — small enough for any space with adequate exercise
  • Alert and vocal enough to serve as an excellent watchdog
  • Low-shedding coat when properly maintained through hand-stripping

Cons

  • Tenacious digger — they will excavate gardens, flower beds, and lawns with enthusiasm
  • Can be stubborn and independent, requiring patient, creative training approaches
  • Strong prey drive makes them unreliable around small pets like hamsters and rabbits
  • Prone to portosystemic liver shunt, cataracts, and globoid cell leukodystrophy

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.
