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 Whippet

The Whippet was developed in Victorian England by coal miners and mill workers who bred small Greyhounds with terriers to create an affordable racing and rabbit-coursing dog — earning the nickname "the poor man's racehorse." These elegant sighthounds stand 18 to 22 inches tall and weigh 25 to 40 pounds, with a streamlined, aerodynamic build capable of reaching speeds up to 35 miles per hour. Their short, smooth coat comes in virtually any color or pattern and lies close to the body, accentuating their graceful, muscular contours.

Temperament & Personality

Whippets are gentle, quiet, and remarkably calm indoors — often spending hours draped elegantly across furniture in poses that would make a greyhound proud. They are affectionate and sensitive with their families, good with children (though their slender build makes them vulnerable to rough play), and generally friendly with other dogs. Despite their sprinting ability, Whippets are surprisingly low-energy at home and are often described as the ideal apartment dog for owners who enjoy outdoor exercise.

Pros

  • Extremely calm and quiet indoors — one of the most unobtrusive housemates
  • Short, low-maintenance coat with minimal shedding and no doggy odor
  • Gentle, affectionate nature — rarely aggressive toward people or other dogs
  • Healthy breed with a long lifespan of 12 to 15 years

Cons

  • Intense prey drive — will chase and potentially catch small animals including cats
  • Thin skin and low body fat make them sensitive to cold and prone to scrapes
  • Cannot be trusted off-leash in unfenced areas — once they run, they cannot hear you
  • Susceptible to anesthesia sensitivity and cardiac arrhythmias

Whippets are the perfect blend of couch companion and outdoor athlete — find one looking for a home on Puplister.
