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 Shiba Inu

The Shiba Inu is Japan's oldest and smallest native breed, originally bred to flush birds and small game in the dense mountain underbrush — "shiba" may refer to brushwood or the breed's red color, while "inu" simply means dog. These compact, agile dogs stand 13.5 to 16.5 inches tall and weigh 17 to 23 pounds, with a fox-like face, small triangular ears, and a curled tail. Their stiff, plush double coat comes in red, sesame, black and tan, or cream, with distinctive "urajiro" (cream to white ventral markings).

Temperament & Personality

Shiba Inus are bold, alert, and fiercely independent — often described as more cat-like than dog-like in their self-possession and fastidious grooming habits. They are loyal to their families but on their own terms, and their strong-willed nature means they do not blindly follow commands. Shibas are known for the infamous "Shiba scream" — a loud, distinctive vocalization produced when displeased or overjoyed — and they can be aloof with strangers and sometimes aggressive toward other dogs.

Pros

  • Naturally clean and almost cat-like — easy to housetrain and self-grooming
  • Compact, manageable size for apartments with adequate exercise
  • Loyal and devoted to their family once trust is established
  • Healthy breed with a long lifespan of 13 to 16 years

Cons

  • Extremely independent and stubborn — not recommended for first-time owners
  • Strong prey drive and unreliable recall make off-leash freedom risky
  • Can be possessive of food, toys, and territory (resource guarding)
  • Prone to allergies, patellar luxation, and hip dysplasia

The Shiba Inu's spirited independence and striking looks have won fans worldwide — discover Shibas on Puplister.
