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 Samoyed

The Samoyed takes its name from the Samoyedic peoples of Siberia, who relied on these dogs for herding reindeer, pulling sleds, and providing warmth in temperatures reaching minus 60 degrees Fahrenheit for over 3,000 years. These striking dogs stand 19 to 23.5 inches tall and weigh 35 to 65 pounds, with a strong, graceful build beneath their profuse coat. Their thick, brilliant white double coat — sometimes with biscuit or cream shading — and characteristic upturned "Sammy smile" make them one of the most beautiful breeds in existence.

Temperament & Personality

Samoyeds are friendly, gentle, and perpetually cheerful — bred to live and work in close quarters with humans, they crave companionship and involvement in family activities. They are wonderful with children, welcoming to strangers, and generally amiable with other dogs — making them poor guard dogs but outstanding family companions. Their intelligence and independent spirit mean they need engaging training methods, as they bore quickly with repetitive exercises.

Pros

  • Perpetually happy disposition — the "Sammy smile" reflects a genuinely joyful temperament
  • Excellent with children and other pets — one of the friendliest breeds
  • Hypoallergenic-type coat produces less dander despite heavy shedding
  • Hardy and athletic — thrives in cold climates and loves outdoor winter activities

Cons

  • Extreme shedding — the voluminous coat blows out twice yearly in spectacular fashion
  • Prone to hip dysplasia, progressive retinal atrophy, and Samoyed hereditary glomerulopathy
  • Tendency to dig, chew, and bark when bored or left alone
  • Suffers significantly in hot climates and requires climate-controlled environments
