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 Whippet

The Whippet was developed in Victorian England by coal miners and mill workers who bred small Greyhounds with terriers to create an affordable racing and rabbit-coursing dog — earning the nickname "the poor man's racehorse." These elegant sighthounds stand 18 to 22 inches tall and weigh 25 to 40 pounds, with a streamlined, aerodynamic build capable of reaching speeds up to 35 miles per hour. Their short, smooth coat comes in virtually any color or pattern and lies close to the body, accentuating their graceful, muscular contours.

Temperament & Personality

Whippets are gentle, quiet, and remarkably calm indoors — often spending hours draped elegantly across furniture in poses that would make a greyhound proud. They are affectionate and sensitive with their families, good with children (though their slender build makes them vulnerable to rough play), and generally friendly with other dogs. Despite their sprinting ability, Whippets are surprisingly low-energy at home and are often described as the ideal apartment dog for owners who enjoy outdoor exercise.

Pros

  • Extremely calm and quiet indoors — one of the most unobtrusive housemates
  • Short, low-maintenance coat with minimal shedding and no doggy odor
  • Gentle, affectionate nature — rarely aggressive toward people or other dogs
  • Healthy breed with a long lifespan of 12 to 15 years

Cons

  • Intense prey drive — will chase and potentially catch small animals including cats
  • Thin skin and low body fat make them sensitive to cold and prone to scrapes
  • Cannot be trusted off-leash in unfenced areas — once they run, they cannot hear you
  • Susceptible to anesthesia sensitivity and cardiac arrhythmias

Whippets are the perfect blend of couch companion and outdoor athlete — find one looking for a home on Puplister.
