Pyrenean Mastiff

Typically 10-13 years, which is actually good for a dog of this size — many giant breeds average 8-10. Lifespan in this breed tracks two things you can influence: keeping the dog lean from puppyhood to protect the joints, and preventing bloat through meal management and a gastropexy. A lean, gastropexied Pyrenean Mastiff from hip-screened parents has a meaningfully better outlook than the breed average suggests.

Generally yes — the breed is selected for low prey drive and a calm, tolerant temperament, and it typically coexists well with children, dogs and livestock it is raised with. The real caution is not aggression but physics: a 60-80 kg dog can knock a small child over without intent, so supervise interactions and never let a toddler be a play target. Early, broad socialization is essential because this is a naturally wary guardian breed.

Less than people expect for the size. Two moderate 20-30 minute walks a day plus space to patrol a property is enough for an adult; this is a low-arousal guardian, not an athlete. Critically, do not over-exercise a puppy — forced running, long hikes, stairs and jumping before 14-18 months damages developing joints in a giant breed. Mental security and a stable territory matter more to this dog than mileage.

Budget well beyond the purchase price. A 70 kg dog eats accordingly, and giant-breed-specific costs add up: a prophylactic gastropexy is roughly $400-$800 (cheaper bundled with spay/neuter), bloat surgery if it happens runs $2,500-$6,000+ as an emergency, and lifelong arthritis management for a dog this size is a recurring expense. Higher-dose medications and anesthesia also cost more by weight. Hip and elbow screened parents are the cheapest insurance against the biggest bills.

Yes — this is a mastiff-type breed with loose flews, and drool is heaviest around food, water and heat. It is not a flaw to be trained away; it is the breed. If a permanently slobber-free house is a hard requirement, this is the wrong breed. Owners typically keep a drool towel by the water bowl and accept it as part of the package, the same way they accept the shedding and the size.

Usually not. The combination of giant size, an independent guardian mindset (bred to make its own decisions, not to obey quickly), serious territorial barking, drool, a cold-weather coat, and giant-breed medical costs is a lot for a first-time owner to manage well. It rewards an owner who wants a calm, protective presence and has the space, fencing, budget and patience for slow relationship-based training rather than fast obedience.
