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 Portuguese Water Dog

The Portuguese Water Dog was developed centuries ago along Portugal's coast, where it served as an indispensable fisherman's companion — herding fish into nets, retrieving lost tackle, and swimming messages between boats. These robust, medium-sized dogs stand 17 to 23 inches tall and weigh 35 to 60 pounds, with a strong, muscular build optimized for swimming. Their coat comes in two varieties — curly or wavy — in black, white, brown, or combinations thereof, and grows continuously like human hair rather than shedding seasonally.

Temperament & Personality

Portuguese Water Dogs are spirited, obedient, and deeply bonded to their families — they thrive on being included in activities and do not do well relegated to the backyard. They are playful and patient with children, typically friendly with other dogs, and possess an enthusiasm for life that is both infectious and demanding. Their intelligence and eagerness to work make them highly trainable, though they need a job or purpose to remain content.

Pros

  • Low-shedding, hypoallergenic-type coat suitable for many allergy sufferers
  • Outstanding swimming ability and love of water activities
  • Highly trainable, biddable, and eager to please
  • Robust health with a lifespan of 11 to 13 years

Cons

  • High exercise demands — needs vigorous daily activity including swimming when possible
  • Coat requires regular professional grooming every 4 to 6 weeks
  • Can become mouthy and destructive if under-stimulated or left alone too long
  • Prone to hip dysplasia, progressive retinal atrophy, and GM1 storage disease
