English Mastiff care guide

The English Mastiff is among the heaviest dogs on earth — an ancient guardian whose modern temperament is dignified calm. Mastiffs guard by presence rather than aggression and are surprisingly gentle, low-energy housemates.

Size: Giant
Lifespan: 6–10 years
Weight: 54–100 kg
Calm
Protective
Docile

Feeding

Carefully managed growth in puppyhood prevents skeletal problems; adult portions are large but must keep them lean. Bloat protocols apply fully.

Exercise

Two moderate daily walks. Forced exercise harms growing joints; adult Mastiffs are happy amblers, not athletes.

Grooming

Easy coat, weekly brushing; clean facial wrinkles regularly and embrace the drool towel.

Common health issues

  • Hip and elbow dysplasia
  • Bloat — discuss preventive gastropexy
  • Cardiomyopathy
  • Cruciate ligament injuries

Frequently asked questions

How expensive is a Mastiff to keep?

Food bills are the obvious cost, but medication dosed by weight, giant-size equipment, and major surgery prices add up — budget like you're keeping a small pony.

Are Mastiffs aggressive guard dogs?

They guard by intimidating presence and a deep bark. Well-bred Mastiffs are steady and tolerant; aggressiveness is a breeding or socialization failure.
