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.
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.
