About the Greyhound

The Greyhound is one of the most ancient breeds — depicted in Egyptian tomb art dating back 5,000 years and prized by nobility throughout history for their unmatched speed and grace. Standing 27–30 inches tall and weighing 60–70 pounds, these aerodynamic athletes can reach speeds of 45 miles per hour, making them the fastest dog breed in the world. Their short, smooth coat comes in virtually every color and pattern, including black, white, fawn, red, blue, brindle, and various combinations.

Temperament & Personality

Greyhounds are gentle, quiet, and surprisingly lazy — the ultimate couch potatoes who happen to be world-class sprinters. They are sweet-natured and sensitive dogs that form deep bonds with their owners and are typically good with older children who respect their space. Many retired racing Greyhounds adapt beautifully to home life, though they may need time to learn household basics like stairs, glass doors, and slippery floors.

Pros

  • Remarkably calm and quiet indoors — content to sleep 18+ hours a day on the couch
  • Low-maintenance coat — virtually no grooming needs and minimal shedding
  • Gentle, non-aggressive temperament — rarely bark and never show hostility toward people
  • Many retired racers are available for adoption — giving these athletes a well-deserved second career

Cons

  • Strong prey drive — cannot be trusted off-leash and may chase small dogs, cats, and wildlife
  • Thin skin and minimal body fat make them susceptible to cuts, cold temperatures, and pressure sores
  • Sensitive to anesthesia and many common medications due to low body fat percentage
  • Prone to osteosarcoma, bloat, and dental disease — especially in retired racing dogs

About the Saint Bernard

The Saint Bernard originated in the Swiss Alps at the Great St. Bernard Hospice, where monks bred these massive dogs for over 1,000 years to locate and rescue travelers lost in snowstorms along the treacherous mountain pass. Males typically stand 28 to 30 inches tall and weigh 140 to 180 pounds, though individuals exceeding 200 pounds are not uncommon. Their coat comes in two varieties — short-haired (smooth) and long-haired (rough) — both in white with red, mahogany, brindle, or brown markings.

Temperament & Personality

Saint Bernards are gentle, patient, and extraordinarily tolerant — their legendary devotion to humans extends to being remarkably careful and nurturing around children despite their massive size. They are friendly with strangers, other dogs, and household pets, possessing a calm, unflappable demeanor that makes them wonderful therapy dogs. While not aggressive, their sheer size and deep bark are often enough to deter unwanted visitors.

Pros

  • Exceptionally gentle and patient — one of the best giant breeds for families with children
  • Calm, low-energy indoor demeanor despite enormous size
  • Friendly and non-aggressive toward people and other animals
  • Imposing presence provides natural deterrent without guard training

Cons

  • Legendary drooling — especially the loose-lipped, heavy-jowled individuals
  • Short lifespan of 8 to 10 years, with some living even less
  • Prone to hip and elbow dysplasia, bloat, osteosarcoma, and dilated cardiomyopathy
  • Enormous food costs and substantial space requirements for comfortable living

Few breeds embody devotion quite like the Saint Bernard — find one in need of a loving home on Puplister.
