About the American Pit Bull Terrier

The American Pit Bull Terrier traces its roots to 19th-century England, where Bulldogs and Terriers were crossed to create a dog combining strength with agility. Standing 17–21 inches tall and weighing 30–60 pounds, the APBT is a medium-sized, solidly built dog with a broad chest and well-defined musculature. Their short, glossy coat comes in virtually every color and pattern — including blue, red, brindle, and merle — and is exceptionally easy to maintain.

Temperament & Personality

Despite their often-misunderstood reputation, American Pit Bull Terriers are among the most people-oriented breeds — they are affectionate, eager to please, and frequently described as "nanny dogs" for their gentleness with children. They are intelligent, loyal, and enthusiastic about training when given positive reinforcement. However, some individuals may exhibit dog-selectivity, and responsible ownership includes understanding their terrier-driven tenacity.

Pros

  • Extremely affectionate and loyal — they bond deeply with every family member
  • Highly trainable and eager to please, excelling in obedience and nosework
  • Low grooming needs with their short, easy-care coat
  • Athletic and energetic — outstanding companion for active lifestyles

Cons

  • Subject to breed-specific legislation and housing restrictions in many areas
  • May develop dog-selectivity, requiring careful management around other dogs
  • Strong and powerful — not ideal for physically frail owners
  • Prone to skin allergies, hip dysplasia, and congenital heart disease

These loving, misunderstood dogs deserve wonderful homes — browse adoptable Pit Bull Terriers on Puplister today.

About the Bullmastiff

The Bullmastiff was developed in 19th-century England by crossing Bulldogs with Mastiffs — the goal was a powerful, silent guardian capable of tracking and pinning poachers on large estates without mauling them. Standing 24–27 inches tall and weighing 100–130 pounds, the Bullmastiff is a massive, muscular dog with a broad head, dark muzzle, and an imposing physical presence. Their short, dense coat comes in fawn, red, or brindle — always with a black mask — and sheds moderately with minimal grooming requirements.

Temperament & Personality

Bullmastiffs are confident, loyal, and naturally protective — they are alert guardians who rely on their size and intimidating presence rather than excessive barking to deter intruders. Despite their imposing appearance, they are gentle and affectionate with their families, showing particular patience and tenderness with children. They are typically calm and quiet indoors, content to lie at their owner's feet, but they can be territorial with unfamiliar dogs and require early, consistent socialization.

Pros

  • Naturally protective — their imposing presence alone is an effective deterrent
  • Surprisingly low-energy indoors, adapting well to a calm household routine
  • Gentle and affectionate with family members, including children
  • Minimal grooming needs with their short, easy-care coat

Cons

  • Short lifespan averaging only 7–9 years
  • Prone to bloat, hip and elbow dysplasia, lymphoma, and mast cell tumors
  • Significant drooling, especially around mealtimes and in warm weather
  • Their sheer size and strength require an experienced owner capable of managing 100+ pounds of dog
