About the American Staffordshire Terrier

The American Staffordshire Terrier — often called the AmStaff — was developed in the United States from crosses between Bulldogs and Terriers, earning AKC recognition in 1936. They stand 17–19 inches at the shoulder and weigh 40–70 pounds, presenting a stocky, muscular build that radiates power and confidence. Their short, stiff coat comes in a wide variety of colors and patterns, including blue, fawn, brindle, and black, and requires only minimal grooming.

Temperament & Personality

AmStaffs are known for their courage, intelligence, and unwavering loyalty to their families — they are genuinely affectionate dogs who love being at the center of household activities. They are typically excellent with children and are known for their patience and tolerance with youngsters. Proper socialization from puppyhood is critical, as they can be assertive with other dogs, and their strength demands a handler who can provide calm, confident leadership.

Pros

  • Incredibly loyal and protective of their family without being overly aggressive
  • Smart and highly trainable — they excel in obedience, rally, and therapy work
  • Short coat makes grooming a breeze
  • Sturdy and athletic, perfect for active families who enjoy outdoor activities

Cons

  • May face breed-specific legislation and insurance restrictions
  • Requires early and ongoing socialization with other dogs and animals
  • Prone to hip dysplasia, cardiac disease, and skin allergies
  • Their strong jaws and determination mean they can destroy toys and furniture quickly

AmStaffs make incredible family companions when given the right home — search for adoptable American Staffordshire Terriers 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
