Dogue de Bordeaux vs Spanish Mastiff

He’s better with families who have older kids and can handle his moderate energy and serious health risks . bloat and heart issues mean you’ll likely face tough vet visits by age 6. The Spanish Mastiff? He’s not a house pet first . he’s a working guardian. At 140 to 200 pounds and standing up to 35 inches, this dog was bred to walk for days with sheep flocks across Spain, facing wolves and thieves. He’s quieter, less driven to please, and needs space . like, a farm or rural property . to exist as he was meant to. You don’t bring a Spanish Mastiff into a suburban home and expect grace; he won’t bark much, but his sheer size and lower trainability demand an experienced hand.
