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 Collie

The Collie — immortalized by the fictional Lassie — originated in Scotland and northern England as a supremely capable herding dog guarding flocks across rugged highland terrain. Standing 22–26 inches tall and weighing 50–75 pounds, the breed comes in two coat varieties — the iconic Rough Collie with its abundant mane and the sleeker Smooth Collie — in sable and white, tricolor, blue merle, and white colorations. Their wedge-shaped head, almond eyes, and graceful build give them an unmistakable elegance among herding breeds.

Temperament & Personality

Collies are among the most gentle and devoted of all breeds — known for their uncanny ability to sense their family's emotions and respond with quiet comfort. They are exceptionally patient with children and often take on a protective, nurturing role with the youngest family members. While friendly toward strangers, they'll alert you to anything unusual with a distinctive bark — though excessive barking can develop without training.

Pros

  • One of the most naturally gentle and trustworthy breeds with children of all ages
  • Highly intelligent and responsive to training — learn commands with minimal repetition
  • Moderate exercise needs — satisfied with daily walks and yard play rather than intense activity
  • Clean dogs with little doggy odor despite their abundant coats

Cons

  • Rough variety sheds heavily year-round and requires thorough brushing 2–3 times weekly
  • Prone to Collie Eye Anomaly — a hereditary condition affecting up to 70% of the breed
  • Can develop nuisance barking if bored or left alone frequently
  • Sensitive to many common veterinary drugs due to the MDR1 gene mutation
