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 Weimaraner

The Weimaraner was developed in the early 19th century at the court of Weimar in Germany, where nobles bred these dogs to hunt large game — boar, bear, and deer — before transitioning them to bird dog duties as large game became scarce. These striking, athletic dogs stand 23 to 27 inches tall and weigh 55 to 90 pounds, with a sleek, powerful build designed for speed and endurance. Their distinctive short, smooth coat comes in shades of mouse-gray to silver-gray — earning them the nickname "Gray Ghost" — complemented by striking amber or blue-gray eyes.

Temperament & Personality

Weimaraners are fearless, friendly, and intensely devoted to their families — they crave human companionship and do not do well as kennel or outdoor-only dogs. They are energetic and playful with children, generally sociable with other dogs, and possess an intelligence that demands both physical and mental outlets. Without adequate exercise and attention, Weimaraners become anxious, destructive, and can develop severe behavioral problems.

Pros

  • Strikingly beautiful with an unmistakable silver-gray appearance
  • Versatile sporting dog — excellent for hunting, running, and competitive events
  • Highly intelligent and trainable with consistent, positive methods
  • Short coat requires minimal grooming and sheds only moderately

Cons

  • Extreme separation anxiety — one of the most prone breeds to this condition
  • Requires intense daily exercise — 2 or more hours of vigorous activity is typical
  • Prone to bloat (gastric torsion), hip dysplasia, and hyperuricosuria
  • Can be destructive on a grand scale when bored or anxious — has been known to eat through drywall

The "Gray Ghost" is a magnificent companion for the active and committed — discover Weimaraners on Puplister.
