About the Australian Shepherd

Despite its name, the Australian Shepherd was actually developed in the western United States during the 19th century, likely from Basque shepherd dogs that passed through Australia on their way to America. These versatile herding dogs stand 18–23 inches tall and weigh 40–65 pounds, with a medium-length double coat that comes in four recognized colors — black, blue merle, red, and red merle — often with striking copper and white markings. Their coats are weather-resistant and require regular brushing to manage moderate-to-heavy shedding.

Temperament & Personality

Australian Shepherds are brilliant, energetic, and deeply devoted to their families — they thrive when given a purpose and can become anxious or destructive without one. They are excellent with children, often naturally herding and watching over younger family members. Aussies are typically friendly with other dogs but can be reserved with strangers, and their intelligence makes them exceptionally responsive to training.

Pros

  • One of the most intelligent and trainable breeds — excels in agility, flyball, and herding
  • Loyal and affectionate family companion who bonds closely with all household members
  • Versatile working dog adaptable to ranch life, sport, or active suburban living
  • Beautiful, eye-catching coat with striking color variations including heterochromia

Cons

  • Demands extensive daily exercise and mental engagement — easily 1–2 hours minimum
  • Heavy shedding, especially during seasonal coat changes
  • May herd children, cats, and other pets by nipping at heels
  • Prone to epilepsy, hip dysplasia, and the MDR1 gene mutation affecting drug sensitivity

Aussies are incredible partners for active families — discover adoptable Australian Shepherds waiting for you on Puplister.

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
