About the Rat Terrier

The Rat Terrier is an American original, developed in the early 20th century on farms across the United States by crossing Fox Terriers with Beagles, Whippets, Italian Greyhounds, and other breeds. They come in two sizes — Miniature (10 to 13 inches, 10 to 18 pounds) and Standard (13 to 18 inches, 12 to 25 pounds) — both with a compact, elegant build. Their short, smooth coat is always pied (white with patches of one or more other colors), and President Theodore Roosevelt is credited with naming the breed after his own terrier cleared the White House of rats.

Temperament & Personality

Rat Terriers are intelligent, curious, and remarkably versatile — combining terrier tenacity with a more biddable, people-oriented temperament than many of their terrier cousins. They bond deeply with their families and are generally good with children, often choosing one person as their particular favorite. Rat Terriers tend to be less dog-aggressive than other terriers, though they retain a strong prey drive toward rodents and small animals.

Pros

  • Excellent farm and homestead dog with natural pest control abilities
  • More trainable and less stubborn than most terrier breeds
  • Minimal grooming needs — short coat requires only occasional brushing
  • Generally healthy breed with a long lifespan of 12 to 18 years

Cons

  • Can be diggers — will excavate impressive holes in gardens and yards
  • High energy level requires daily exercise and mental engagement
  • Prone to patellar luxation, hip dysplasia, and cardiac issues
  • May be wary of strangers and needs early socialization to prevent timidity

About the Shiba Inu

The Shiba Inu is Japan's oldest and smallest native breed, originally bred to flush birds and small game in the dense mountain underbrush — "shiba" may refer to brushwood or the breed's red color, while "inu" simply means dog. These compact, agile dogs stand 13.5 to 16.5 inches tall and weigh 17 to 23 pounds, with a fox-like face, small triangular ears, and a curled tail. Their stiff, plush double coat comes in red, sesame, black and tan, or cream, with distinctive "urajiro" (cream to white ventral markings).

Temperament & Personality

Shiba Inus are bold, alert, and fiercely independent — often described as more cat-like than dog-like in their self-possession and fastidious grooming habits. They are loyal to their families but on their own terms, and their strong-willed nature means they do not blindly follow commands. Shibas are known for the infamous "Shiba scream" — a loud, distinctive vocalization produced when displeased or overjoyed — and they can be aloof with strangers and sometimes aggressive toward other dogs.

Pros

  • Naturally clean and almost cat-like — easy to housetrain and self-grooming
  • Compact, manageable size for apartments with adequate exercise
  • Loyal and devoted to their family once trust is established
  • Healthy breed with a long lifespan of 13 to 16 years

Cons

  • Extremely independent and stubborn — not recommended for first-time owners
  • Strong prey drive and unreliable recall make off-leash freedom risky
  • Can be possessive of food, toys, and territory (resource guarding)
  • Prone to allergies, patellar luxation, and hip dysplasia

The Shiba Inu's spirited independence and striking looks have won fans worldwide — discover Shibas on Puplister.
