About the Mastiff

The English Mastiff is one of the most ancient and massive dog breeds, with roots tracing back over 2,000 years to ancient Britain and possibly earlier Molosser-type dogs of Asia. Males commonly weigh 160 to 230 pounds and stand 30 inches or taller at the shoulder, making them among the heaviest domestic dogs in the world. Their short, dense double coat comes in fawn, apricot, or brindle — always with a distinctive dark mask on the face.

Temperament & Personality

Despite their imposing size, Mastiffs are famously gentle, calm, and deeply loyal — often called "gentle giants" with good reason. They are patient and protective with children in their family, though their sheer mass means supervision around small kids is wise. Mastiffs tend to be reserved with strangers but rarely aggressive, preferring to position themselves between their family and any perceived threat.

Pros

  • Naturally protective without needing guard training
  • Surprisingly low energy indoors — content to lounge for hours
  • Gentle and patient temperament ideal for families
  • Short coat requires only basic weekly brushing

Cons

  • Massive food bills — adult Mastiffs eat 6 to 10 cups of food daily
  • Shorter lifespan of 6 to 10 years typical of giant breeds
  • Prone to hip dysplasia, bloat (gastric torsion), and heart conditions
  • Excessive drooling is a constant reality with this breed

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.
