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

About the West Highland White Terrier

The West Highland White Terrier — universally known as the "Westie" — was developed in Scotland's western highlands during the 19th century, selectively bred from Cairn Terrier stock for its white coat to be more visible against the dark highland terrain while hunting foxes, badgers, and rats. These sturdy little dogs stand 10 to 11 inches tall and weigh 15 to 20 pounds, with a compact, balanced build and surprisingly strong legs for their size. Their double coat features a hard, straight white outer layer and a soft, dense undercoat — always pure white without exception.

Temperament & Personality

Westies are confident, entertaining, and surprisingly tough — carrying the classic terrier self-assurance in a friendly, less aggressive package than many of their terrier relatives. They are affectionate with their families, generally good with older children, and possess an independent, adventurous spirit that keeps life interesting. Westies are social dogs that enjoy meeting people, though they can be assertive with other dogs and retain a strong instinct to chase anything that moves.

Pros

  • Sturdy and adaptable — thrives in apartments, suburbs, and country settings
  • Friendly and sociable without the extreme aggression of some terrier breeds
  • Portable size with a big, confident personality
  • Alert watchdog that will reliably announce visitors

Cons

  • Prone to atopic dermatitis and skin allergies — one of the most affected breeds
  • Coat requires regular professional grooming or hand-stripping every 6 to 8 weeks
  • Can be stubborn and willful during training — responds best to positive methods
  • Tendency to dig and bark, especially when bored or left in the yard

Westies bring Scottish charm and terrier spirit into every home — find your white-coated companion on Puplister.
