About the Chihuahua

The Chihuahua is the world's smallest dog breed, originating from the Mexican state of Chihuahua where ancestors of the breed were kept by the ancient Toltec civilization. Standing just 5–8 inches tall and weighing a mere 2–6 pounds, these tiny dogs come in smooth-coat and long-coat varieties with virtually every color and pattern combination imaginable. Despite their diminutive size, Chihuahuas carry themselves with a bold, terrier-like confidence that belies their fragile frame.

Temperament & Personality

Chihuahuas are fiercely devoted to one person — often forming an almost obsessive bond with their chosen human. They are alert, spirited, and surprisingly courageous, frequently standing up to dogs many times their size without hesitation. While they can be wonderful companions for older children who handle them gently, their small size and tendency toward snappiness make them a poor match for households with toddlers.

Pros

  • Perfect apartment dogs — minimal space and exercise requirements
  • Exceptionally long lifespan of 14–18 years, among the longest of any breed
  • Portable size makes them easy travel companions for on-the-go owners
  • Low food costs and minimal grooming needs — especially the smooth-coat variety

Cons

  • Prone to patellar luxation, heart murmurs, hydrocephalus, and dental overcrowding
  • Fragile bones — easily injured by falls, rough play, or being stepped on
  • Notoriously difficult to housebreak due to tiny bladders and stubborn temperament
  • Tendency toward excessive barking and aggression toward strangers if not properly socialized

About the Scottish Terrier

The Scottish Terrier — often called the "Scottie" — is one of Scotland's oldest terrier breeds, developed in the Aberdeen area during the 18th and 19th centuries to hunt foxes, badgers, and rats underground. These compact, powerful dogs stand about 10 inches tall and weigh 18 to 22 pounds, with a low center of gravity and surprisingly heavy bone for their size. Their harsh, wiry outer coat and soft, dense undercoat come in black, wheaten, or brindle, and the breed's distinctive profile — long head, erect ears, and bushy eyebrows — is among the most recognizable in dogdom.

Temperament & Personality

Scottish Terriers are independent, dignified, and fiercely loyal to their people — often described as having an "old soul" quality uncommon in the terrier group. They tend to bond most deeply with one or two people and can be reserved or aloof with strangers, making them natural watchdogs. Scotties can be assertive with other dogs, especially those of the same sex, and their strong prey drive means small animals are rarely safe in their presence.

Pros

  • Compact and sturdy — well-suited for apartment living with regular exercise
  • Low-shedding wiry coat when properly maintained through hand-stripping
  • Loyal, devoted companion with a dignified, independent character
  • Excellent watchdog — alert and naturally suspicious of strangers

Cons

  • Stubbornly independent — training requires patience and creative motivation
  • Prone to von Willebrand's disease (a bleeding disorder), Scottie cramp, and bladder cancer
  • Can be aggressive toward other dogs, especially unfamiliar ones
  • Requires regular professional grooming or hand-stripping every 6 to 8 weeks

The Scottish Terrier's unwavering loyalty and distinctive charm are one of a kind — find your Scottie on Puplister.
